W3F11A2218AT1F

Overview

The W3F11A2218AT1F is a surface-mount feedthrough capacitor manufactured by KYOCERA AVX. It features a capacitance of 220 pF with a tolerance of -20% to +50%. The device has a DC voltage rating of 100 V and operates within a temperature range of -55°C to 125°C. It utilizes an NP0 (C0G) dielectric for stability. The component is housed in a 1206 (3216 metric) package with four terminals, measuring 3.2 mm in length, 1.6 mm in width, and 1.27 mm in height. It supports a current rating of 300 mA and has a maximum DC resistance of 600 mΩ.

Feature Summary

• Three-terminal feedthrough design providing effective electromagnetic interference filtering
• NP0 dielectric ensures stable capacitance across wide temperature variations
• Surface-mount construction facilitates automated assembly on printed circuit boards

Applications

• High-frequency signal line filtering in electronic circuits
• Power supply decoupling for noise suppression
• Electromagnetic compatibility enhancement in sensitive devices

Procurement Notes

Verify the specific suffix 'T1F' corresponds to the required tape-and-reel packaging configuration. Confirm that the 1206 footprint matches the target PCB layout. Ensure the 100V DC rating meets the operational voltage requirements. Check RoHS compliance status if restricted substances are mandated. Validate terminal availability against the four-pad requirement.

Selection Notes

Select this component when high-frequency noise attenuation is critical in space-constrained designs. The three-terminal architecture offers superior performance compared to standard two-terminal capacitors. Consider the 300 mA current handling capability for power applications. The NP0 characteristic is suitable for precision timing or RF circuits requiring minimal drift. Evaluate the 1206 size against available board real estate.
