W3F15C1038AT1F

Overview

The W3F15C1038AT1F is a surface-mount feedthrough capacitor from the KYOCERA AVX W3F series. It features a capacitance of 10 nF with an X7R temperature coefficient and a rated DC voltage of 50 V. The component utilizes a 1206 (3216 Metric) package with four PCB pads. Key electrical specifications include a maximum DC resistance of 600 mOhm and a current rating of 300 mA. It operates within a temperature range of -55°C to +125°C.

Feature Summary

• Three-terminal feedthrough architecture providing integrated filtering and grounding in a single surface-mount package.
• High current handling capability suitable for power line noise suppression applications.
• Compact 1206 footprint designed for space-constrained printed circuit board layouts.

Applications

• Smart meter internal circuitry protection
• Power supply input/output filtering
• Noise suppression on data and control lines

Procurement Notes

Verify the specific suffix 'AT1F' against official datasheets to confirm packaging and tape-and-reel specifications. Ensure the X7R dielectric characteristics align with thermal requirements. Cross-reference manufacturer part numbers directly to avoid confusion with similar series variants or alternate termination options.

Selection Notes

Select this component when a compact, high-current feedthrough filter is required for 50V circuits. The 1206 package offers a balance between size and power handling. Consider the X7R dielectric stability for applications with moderate temperature variations. Verify that the 300 mA current rating meets the specific line load requirements.

Part Context

This part belongs to the W3F series of surface-mount feedthrough capacitors. These components are engineered to replace traditional discrete inductor-capacitor networks. They provide superior high-frequency noise attenuation in a small form factor, making them ideal for modern electronics requiring efficient EMI management.

Replacement Considerations

W3F15C2228AT1A is listed as a parameter equivalent by distributors, though it specifies 2200 pF capacitance rather than 10 nF. Verify functional compatibility before substitution. No other direct substitutes are confirmed in public documentation.
