W2F11A2218AT1F

Overview

The W2F11A2218AT1F is a surface-mount feedthrough capacitor from the KYOCERA AVX W2F series. It features a 220 pF capacitance with C0G (NP0) dielectric and a 100 VDC voltage rating. The component operates within a temperature range of -55°C to +125°C and has a tolerance of -20% to +50%. Packaged in an 0805 (2012 metric) footprint, it supports a maximum current of 300 mA and exhibits a maximum DC resistance of 600 mOhms. The device provides effective electromagnetic interference filtering for high-frequency applications up to 5 GHz.

Feature Summary

• Three-terminal feedthrough architecture providing low-inductance signal paths and enhanced high-frequency noise suppression
• C0G (NP0) ceramic dielectric ensuring stable capacitance performance across wide temperature variations
• Surface-mount construction designed for automated assembly and compact board integration

Applications

• Smart metering systems requiring robust EMI filtering
• Alternate energy application circuits
• High-frequency signal conditioning boards

Procurement Notes

Verify the specific suffix 'T1F' against procurement requirements, as it indicates tape-and-reel packaging which differs from cut-tape or tray options. Confirm that the 300 mA current rating and 600 mOhm DCR meet the target circuit's power handling needs. Ensure the -20% to +50% tolerance aligns with the design's precision constraints before finalizing orders.

Selection Notes

Select this component when a 220 pF value is required in an 0805 package with a 100 VDC rating. The W2F series offers lower current handling compared to the W2H series; verify if the 300 mA limit suffices for the application. The C0G dielectric is suitable for stable filtering where minimal capacitance drift is critical. Consider the 4-terminal pad layout during PCB footprint design.

Part Context

This part belongs to the W2F series of surface-mount feedthrough capacitors. It shares the same physical dimensions and electrical characteristics as the W2F11A2218AT1A, differing primarily in packaging format. The series is engineered for compact electronic designs requiring reliable high-frequency noise attenuation in space-constrained environments.

Replacement Considerations

The W2F11A2218AT1A is a parameter-equivalent substitute offering identical electrical specifications. Verify that the alternative packaging format meets production line requirements without altering the PCB footprint or assembly process.
