W3F11A2208AT1A

Overview

The W3F11A2208AT1A is a surface-mount feedthrough capacitor from the KYOCERA AVX W3F series. It features a 22 pF capacitance with -20%, +50% tolerance and a 100 VDC rated voltage. The component utilizes C0G (NP0) dielectric for stable performance across a -55°C to +125°C operating range. Housed in a 1206 (3216 metric) package with four PCB pads, it offers a maximum DC resistance of 600 mOhms and a current rating of 300 mA.

Feature Summary

• Provides effective electromagnetic interference suppression through low-inductance feedthrough construction
• Maintains capacitance stability under varying temperature conditions using C0G/NP0 dielectric
• Supports high-frequency noise filtering with minimal signal distortion

Applications

• Smart meter RF circuitry protection
• Automotive electronic control unit (ECU) power line filtering
• Industrial IoT device signal integrity maintenance

Procurement Notes

Verify the specific suffix '11' against datasheet revisions to ensure compatibility with existing board layouts. Confirm that the 1206 footprint matches the design intent, as the W2F series uses a smaller 0805 package. Check RoHS3 compliance status if required by regional regulations. Validate insulation resistance specifications for high-voltage isolation requirements in the target application.

Selection Notes

Select this component when a compact 1206 footprint is required for feedthrough filtering. Choose over the W2F series if board space allows for larger dimensions but higher reliability is needed. Ensure the 300 mA current rating meets the circuit's peak load demands. Verify that the 100V rating exceeds the maximum operating voltage including transients.

Part Context

This part belongs to the W3F series of multilayer ceramic feedthrough capacitors. It serves as a direct replacement for the discontinued W3F41A2208AT1F. The series is designed for surface-mount assembly, offering improved mechanical stability compared to traditional through-hole feedthrough capacitors while maintaining similar electrical performance characteristics.

Replacement Considerations

The W3F41A2208AT1F is a confirmed parameter-equivalent substitute. Verify pinout compatibility before substitution.
