W3F11A2218AT3A

Overview

The KYOCERA AVX W3F11A2218AT3A is a surface-mount feedthrough capacitor from the W3F series. It features a C0G (NP0) dielectric and a 220 pF capacitance with -20%/+50% tolerance. Rated for 100 VDC, it operates within a temperature range of -55°C to +125°C. The component utilizes a 1206 (3216 metric) package with four terminals. Key electrical specifications include a maximum DC resistance of 600 mOhms, a current rating of 300 mA, and an insulation resistance of 1 GOhm.

Feature Summary

• Provides electromagnetic interference suppression through integrated three-terminal filter architecture
• Maintains stable capacitance characteristics via C0G (NP0) ceramic dielectric material
• Enables compact circuit design using a standard 1206 surface-mount footprint

Applications

• Surface mount applications requiring EMI filtering in compact form factors
