The CHV2220N1K0103KCT from Cal-Chip Electronics, Inc. is a surface-mount multilayer ceramic capacitor (MLCC) delivering 10,000 pF capacitance with a 1000V voltage rating in a 2220 (5750 metric) package. This high voltage ceramic capacitor combines C0G (Class I NP0) dielectric stability with ±10% tolerance, making it suitable for precision timing, filtering, and coupling applications where capacitance drift must remain minimal across temperature and voltage swings.
The C0G/NP0 temperature coefficient ensures near-zero capacitance variation from -55°C to 125°C, a characteristic that distinguishes Class I ceramics from higher-K dielectrics prone to voltage and temperature dependency. This stability is paired with a 1 kV rated voltage, enabling the component to serve in power conversion stages, high-voltage bias networks, and industrial control circuits where transient suppression and energy storage under elevated potential are required. The 10 nF capacitance value positions the part between typical decoupling ranges and larger bulk capacitors, often used in snubber networks, DC-link filtering for motor drives, and high-frequency resonant circuits.
Housed in a 2220 footprint measuring 5.70 mm × 5.00 mm with a maximum thickness of 3.00 mm, the CHV2220N1K0103KCT offers a compact surface-mount solution for designs constrained by board space yet demanding high voltage clearance. The package size accommodates the thicker dielectric layers necessary to achieve 1 kV breakdown strength while maintaining low equivalent series resistance (ESR) and inductance inherent to MLCC construction. Surface-mount assembly is compatible with standard reflow profiles, and the component carries a Moisture Sensitivity Level 1 rating, eliminating baking requirements prior to soldering.
Cal-Chip's CHV series targets general-purpose applications where reliable performance under high voltage and wide temperature excursions is non-negotiable. The part is RoHS3 compliant and REACH unaffected, meeting international environmental and material regulations for commercial and industrial deployment. With over 11,000 pieces available in tape and reel packaging, the CHV2220N1K0103KCT supports volume production runs in power supplies, automotive electronics, telecommunications infrastructure, and test equipment where stable, high-voltage capacitance is specified.

Replacing Cal-Chip CHV2220N1K0103KCT Without Changing the High-Voltage MLCC Design Margin
When a 10,000 pF high-voltage ceramic capacitor becomes constrained by lead time, approved vendor list changes, or end-of-life risk, the replacement decision cannot be made from capacitance and voltage rating alone. Cal-Chip Electronics CHV2220N1K0103KCT is a 2220-size, 1 kV, C0G/NP0 MLCC, so the substitute must preserve low capacitance drift, stable AC behavior, suitable board footprint, and adequate insulation margin.

What Defines the Cal-Chip Electronics CHV2220N1K0103KCT Baseline
The original component, Cal-Chip Electronics CHV2220N1K0103KCT, is a surface-mount multilayer ceramic capacitor from the CHV high-voltage series. Its main electrical identity is 10000 pF, ±10%, 1000 V rated voltage, C0G/NP0 dielectric, in a 2220 package.
| Parameter | CHV2220N1K0103KCT Baseline | Replacement Impact |
|---|---|---|
| Capacitance | 10000 pF / 10 nF | Replacement should match 103 capacitance code unless circuit analysis allows adjustment |
| Tolerance | ±10% | Tighter tolerance is usually acceptable; wider tolerance may affect filters, timing, or resonance |
| Voltage rating | 1000 V DC | Alternative should meet or exceed operating voltage with derating margin |
| Dielectric | C0G/NP0 | Should remain C0G/NP0 for stable capacitance, low loss, and minimal DC bias effect |
| Package | 2220 / 5750 metric | Determines PCB land pattern compatibility and voltage spacing |
| Dimensions | Approx. 5.70 mm x 5.00 mm; max thickness 3.00 mm | Height and solder fillet geometry must be checked against enclosure and assembly rules |
| Mounting | Surface mount MLCC | Replacement must match reflow process and board assembly capability |
| Operating temperature | -55°C to +125°C | Alternatives should support the same environmental range |
| Packaging | Tape & Reel | Important for automated SMT production |
| Compliance | RoHS3, REACH unaffected, MSL 1 | Helps avoid process or regulatory requalification issues |
The C0G/NP0 dielectric is one of the main reasons this capacitor cannot be replaced casually with an X7R or X5R part. In high-voltage filtering, snubber networks, resonant circuits, coupling paths, and precision impedance networks, C0G provides low temperature coefficient, low dielectric absorption, and minimal capacitance loss under DC bias. A same-value X7R capacitor may measure correctly at low voltage but can lose significant capacitance under bias and temperature.
The 2220 body size also matters. It provides physical spacing and energy-handling capability better suited to 1 kV applications than smaller MLCC packages. However, the larger ceramic body is more exposed to board flex stress, so replacement selection should also consider termination style, solder joint design, and mechanical mounting conditions.

Engineering Trade-Offs Between CHV2220N1K0103KCT Alternatives
| Decision Factor | 2220AA103KAT1A | C2220C103KDGACTU | GRM55C5C3A103JA01L | C5750C0G3A103K230KA | VJ2220A103KXBAT |
|---|---|---|---|---|---|
| Electrical compatibility | Closest match to Cal-Chip CHV2220N1K0103KCT | Strong match for 10 nF, 1 kV, C0G | Strong match with tighter tolerance | Strong match for same capacitance, voltage, and dielectric | Likely compatible if voltage suffix is confirmed |
| Dielectric behavior | C0G/NP0 stability supports low drift and low loss | C0G behavior suitable for precision HV use | C0G with tighter tolerance supports more predictable impedance | C0G suitable for stable AC and DC performance | C0G/NP0 behavior expected; verify datasheet coding |
| Mechanical compatibility | 2220 package supports similar PCB footprint | Same 2220 footprint class, but height must be checked | 5750 metric package generally footprint-compatible | 5750 metric package; thickness code should be reviewed | 2220 footprint class; termination details need confirmation |
| Performance differences | Minimal expected difference if all codes match | May differ in ESR/ESL and insulation resistance details | Tighter tolerance may reduce circuit spread | Comparable high-voltage C0G behavior; verify ripple and pulse conditions | Depends on exact Vishay construction and voltage code |
| Reliability considerations | Good candidate for direct qualification | Established high-voltage MLCC option | Strong process consistency; check application voltage derating | Suitable for multi-source reliability planning | Useful if validated under same voltage, thermal, and flex conditions |
| Package and production availability | Tape-and-reel format typically suitable for SMT | Common SMT production format | May vary by reel quantity and regional stock | Widely supported manufacturer ecosystem | Availability depends on distributor stock and suffix |
| Cost considerations | Often selected for lowest requalification effort | May be cost-effective depending on supply chain | Tighter tolerance may carry price premium | Competitive for high-volume sourcing | May be useful when supply diversification offsets qualification cost |
| Best-fit scenario | Near drop-in replacement for the original Cal-Chip part | Standard second-source for 1 kV C0G 2220 MLCC designs | Precision filtering or tolerance-sensitive circuits | Designs needing broad manufacturer support | Additional approved source after datasheet verification |
| Main limitation | Still requires datasheet and sample validation | Mechanical and termination differences may require review | Tighter tolerance does not automatically mean lower total cost | Height and part-code details should be confirmed | Exact coding must be verified before approval |
For most replacement decisions, the first filter should be dielectric class. A 10000 pF, 1 kV capacitor in the same 2220 package but with X7R dielectric is not a true equivalent to Cal-Chip CHV2220N1K0103KCT when capacitance stability, low loss, or voltage coefficient behavior affects the circuit. The next filter is voltage margin. Even when all candidates are rated 1 kV, the actual operating voltage, transient exposure, altitude, contamination environment, and board spacing influence whether the replacement has enough design margin.
Mechanical review should not be skipped. Large 2220 MLCCs can be affected by PCB bending, depanelization stress, and solder joint geometry. If the original design has experienced cracking or field failures, the replacement decision may also need to include soft termination versions or layout changes, even when the electrical part number appears equivalent.
From a sourcing perspective, Kyocera AVX
2220AA103KAT1A
is the most straightforward substitute to evaluate first. KEMET C2220C103KDGACTU and TDK C5750C0G3A103K230KA are practical alternatives for building a multi-source AVL. Murata GRM55C5C3A103JA01L is worth considering where tighter tolerance improves circuit behavior, while Vishay VJ2220A103KXBAT can be reviewed as an additional supply option after confirming the exact datasheet configuration.
