Packaging & ESD

Industry-standard static shielding packaging is used for electronic components.Anti-static, light-transparent materials allow easy identification of ICs and PCB assemblies.
The packaging structure provides electrostatic protection based on Faraday cage principles.This helps protect sensitive components from static discharge during handling and transportation.


All products are packed in ESD-safe anti-static packaging. Outer packaging labels include part number, brand, and quantity for clear identification. Goods are inspected prior to shipment to ensure proper condition and authenticity.

ESD protection is maintained throughout packing, handling, and global transportation. Secure packaging provides reliable sealing and resistance during transit. Additional cushioning materials are applied when required to protect sensitive components.

Frequently Asked Questions

What are the key design considerations when integrating the TDK CK45-R3DD221KAVRA into a high-voltage circuit with switching frequencies above 100 kHz?
The TDK CK45-R3DD221KAVRA features an R temperature characteristic dielectric that provides low dissipation factor, which helps limit self-heating in high-frequency, high-voltage scenarios. Engineers should verify that the 7.5 mm lead spacing and 7.5 mm diameter allow sufficient clearance for creepage and insulation in the target PCB layout, and account for the through-hole mounting when calculating parasitic inductance in the current path.
How does the operating temperature range of the TDK CK45-R3DD221KAVRA affect its suitability for industrial control systems running continuously at 85°C ambient?
The TDK CK45-R3DD221KAVRA is rated for an operating temperature up to +105°C, including self-generated heat. In continuous 85°C ambient industrial environments, the remaining thermal margin should be evaluated against expected ripple current and voltage stress to ensure the capacitor body temperature remains within limits over the product lifecycle.
Can the TDK CK45-R3DD221KAVRA be used as a drop-in replacement for older 2 kV 220 pF disc capacitors with different temperature characteristics in existing designs?
The TDK CK45-R3DD221KAVRA uses the R characteristic dielectric, which exhibits specific capacitance variation over temperature. Designers migrating from parts with B or E characteristics will need to model the resulting capacitance stability across the application's temperature profile and verify that the ±10% tolerance at 25°C combined with the R behavior meets circuit timing or filtering requirements.
What power supply decoupling or snubber constraints should be evaluated when selecting the TDK CK45-R3DD221KAVRA for 1.5 kV DC bus applications?
With its 2 kV rating, the TDK CK45-R3DD221KAVRA provides headroom above 1.5 kV DC, but designers must consider voltage derating guidelines under temperature and potential transients. The 220 pF value combined with low dissipation supports snubber or decoupling roles where minimal losses are needed, provided the pin spacing of 7.5 mm maintains adequate isolation from adjacent high-voltage nodes.
In what application scenarios might the TDK CK45-R3DD221KAVRA not deliver optimal performance due to its capacitance and voltage rating?
The 220 pF capacitance of the TDK CK45-R3DD221KAVRA suits high-impedance or high-frequency filtering rather than bulk energy storage. Applications requiring significantly higher capacitance at 2 kV or operation with sustained high RMS ripple current may need alternative configurations or multiple paralleled units to achieve the desired impedance and thermal behavior.
When migrating from a similar 2 kV ceramic disc capacitor of another brand to the TDK CK45-R3DD221KAVRA, what mechanical and electrical trade-offs typically arise?
The TDK CK45-R3DD221KAVRA has a 7.5 mm diameter and 7.5 mm lead spacing, which may require PCB footprint adjustments if the original part differs in body size or lead forming. Electrically, the R dielectric offers low dissipation, but capacitance change over temperature and voltage bias should be compared against the prior component to determine any impact on resonance frequency or filter cutoff in the circuit.
How should long-term reliability be assessed for the TDK CK45-R3DD221KAVRA in outdoor or high-humidity industrial equipment?
The through-hole construction and resin coating of the TDK CK45-R3DD221KAVRA provide baseline environmental protection, but designers should apply standard humidity and temperature cycling derating practices for high-voltage ceramics. Monitoring insulation resistance degradation over time under combined DC bias and environmental stress helps predict field behavior in extended operation.
What clocking or timing circuit implications follow from using the TDK CK45-R3DD221KAVRA in RC networks exposed to wide temperature swings?
The R temperature coefficient of the TDK CK45-R3DD221KAVRA results in a defined capacitance variation across temperature, which directly influences RC time constants. Engineers should simulate the network over the full operating range to quantify drift in timing accuracy and determine whether compensation components or tighter-tolerance alternatives are needed for precision requirements.
Are there specific configuration or soldering constraints when incorporating multiple TDK CK45-R3DD221KAVRA units in parallel for higher effective capacitance in high-voltage designs?
Paralleling the TDK CK45-R3DD221KAVRA requires attention to matched lead lengths and symmetric PCB layout to minimize current imbalance and added inductance. The ±10% tolerance means the combined capacitance spread should be calculated, and thermal coupling between closely spaced units evaluated to avoid localized heating under load.
What factors influence the choice between the TDK CK45-R3DD221KAVRA and higher-voltage-rated disc capacitors in 1.8 kV peak applications with occasional transients?
The 2 kV rating of the TDK CK45-R3DD221KAVRA accommodates 1.8 kV peaks with limited margin, so transient amplitude, duration, and repetition rate must be characterized. Where transients regularly approach or exceed this level, a higher-rated part may reduce the risk of dielectric stress over time while maintaining similar 220 pF nominal value and low-dissipation behavior.
