W2F11A1018AT1A

Overview

The W2F11A1018AT1A is a surface-mount feedthrough capacitor manufactured by KYOCERA AVX. It features a capacitance of 100 pF with a tolerance of -20% and +50%. The device has a DC voltage rating of 100 VDC and utilizes C0G (NP0) dielectric material. Rated for a maximum current of 300 mA, it exhibits a maximum DC resistance of 600 mOhms. The component operates within a temperature range of -55°C to +125°C. It is housed in an 0805 (2012 metric) package measuring 2.01 mm in length, 1.25 mm in width, and 1.14 mm in height.

Feature Summary

• Provides effective electromagnetic interference filtering through three-terminal feedthrough architecture
• Maintains stable capacitance characteristics across wide temperature variations using C0G dielectric
• Supports high-current applications with a rated capacity of 300 mA

Applications

• Smart meter circuitry
• High-frequency signal filtering
• Power supply noise suppression

Procurement Notes

Verify the specific suffix designation during procurement, as variants such as AT1A and AT1F may differ in packaging or reel specifications. Confirm RoHS compliance status and moisture sensitivity level requirements against project standards. Ensure the selected variant matches the required termination type and reel quantity for automated assembly processes.

Selection Notes

Select this component when a compact 0805 footprint is required for high-frequency filtering. Choose this model over higher-resistance alternatives if the circuit demands lower insertion loss with a 300 mA current rating. Consider the W2H series if a higher current capacity of 500 mA is necessary for the same capacitance value.

Part Context

This component belongs to the W2F series of surface-mount feedthrough capacitors from KYOCERA AVX. The series is designed for applications requiring efficient noise suppression in small form factors. These devices are commonly utilized in electronic systems where space constraints limit the use of traditional discrete filter components.

Replacement Considerations

W2F11A1018AT1F is documented as a parameter-equivalent substitute.
