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 board flex and mechanical stress considerations arise when integrating the 2220Y3K00120FCT Knowles Syfer capacitor into designs with large PCBs or multiple reflow cycles?
The 2220Y3K00120FCT features FlexiCap™ soft termination, which allows the assembly to accommodate approximately twice the board bending before mechanical cracking of the ceramic body occurs compared to standard nickel-barrier terminations. This behavior supports use in boardflex-sensitive applications during handling, depanelization, or operation in environments with vibration and thermal expansion mismatch, while maintaining compatibility with standard reflow and wave soldering processes up to a maximum recommended peak of 270°C.
How does the FlexiCap™ termination on the 2220Y3K00120FCT affect long-term reliability under repeated temperature cycling in industrial equipment?
In the 2220Y3K00120FCT, the polymer-based FlexiCap™ layer absorbs mechanical strain between the PCB and the rigid ceramic, enabling the part to withstand temperature cycling from -55°C to 125°C for more than 1,000 cycles with reduced risk of cracking. The C0G/NP0 dielectric further contributes stable electrical parameters with negligible aging or hysteresis over time and temperature.
When replacing a standard 2220 C0G 12pF 3kV MLCC with the 2220Y3K00120FCT in an existing high-voltage circuit, what design adjustments are typically needed?
The 2220Y3K00120FCT is a drop-in replacement for standard-terminated equivalents in the 2220 package with matching 12pF ±1% and 3000V ratings, as the FlexiCap™ termination does not alter the core electrical characteristics such as capacitance, dissipation factor, or insulation resistance. No changes to land pattern or soldering process parameters are required, though the enhanced mechanical robustness may allow relaxation of some board-level strain relief measures in flex-prone layouts.
Is the 2220Y3K00120FCT suitable for high-voltage DC blocking or coupling applications where voltage stability and minimal capacitance variation are required?
The C0G/NP0 dielectric in the 2220Y3K00120FCT provides near-zero capacitance change with applied DC voltage or frequency, combined with the 3000V rating, making it appropriate for precision high-voltage coupling, DC blocking, and tank circuits. Designers should verify creepage and clearance distances on the PCB consistent with the 2220 case size and operating voltage to maintain insulation integrity.
What power supply and decoupling considerations apply when evaluating the 2220Y3K00120FCT for snubber or filtering roles in high-voltage converters?
With its low parasitic inductance typical of the 2220 MLCC format and stable C0G behavior, the 2220Y3K00120FCT can serve in high-frequency sections of snubber networks or as a high-voltage bypass element, where the 12pF value limits its effectiveness for bulk energy storage but supports transient suppression. Thermal management remains straightforward due to the low dissipation factor across the -55°C to 125°C range.
What are the practical differences when migrating from a lower-voltage 2220 C0G capacitor to the 2220Y3K00120FCT in designs approaching 3kV stress levels?
The 2220Y3K00120FCT offers a 3000V rating with C0G stability, providing margin in applications where peak voltages or transients exceed 1-2kV, unlike lower-voltage equivalents that may require series connections or additional derating. The FlexiCap™ termination adds mechanical resilience without impacting ESR/ESL or requiring layout modifications beyond standard high-voltage spacing rules.
In industrial or harsh-environment applications, how does the operating temperature range of the 2220Y3K00120FCT influence long-term performance expectations?
The 2220Y3K00120FCT operates from -55°C to 125°C with the C0G/NP0 dielectric maintaining its ±30ppm/°C temperature coefficient and high insulation resistance throughout. This supports consistent behavior in equipment exposed to wide thermal swings, where the soft termination further mitigates stress-induced failures from coefficient-of-thermal-expansion mismatches.
Can the 2220Y3K00120FCT be used in safety-critical or high-reliability systems without additional screening, and what factors affect its suitability?
The 2220Y3K00120FCT is ROHS3 compliant with MSL 1 and carries no specified failure rate or extended hi-rel screening in its base configuration; for mission-critical use, engineers often apply additional burn-in, voltage conditioning, or lot traceability per application standards. Its FlexiCap™ construction and C0G dielectric inherently reduce common mechanical and parametric drift mechanisms observed in standard MLCCs.
What configuration or soldering constraints should be observed when placing multiple 2220Y3K00120FCT capacitors near high-voltage traces or in dense layouts?
Standard 2220 land patterns apply to the 2220Y3K00120FCT, with attention to maintaining adequate spacing for the 3kV rating to prevent surface arcing or tracking. The soft termination tolerates typical assembly stresses, allowing placement in areas subject to minor board warpage, provided reflow profiles stay within lead-free guidelines and post-assembly cleaning avoids aggressive chemistries that could affect the termination integrity.
