W3F15C1028AT3A

Overview

The KYOCERA AVX W3F15C1028AT3A is a surface-mount feedthrough capacitor from the W3F series, designed for high-frequency noise suppression. It features a capacitance of 1000 pF with a tolerance of -20% to +50%, rated for 50 VDC. The component utilizes X7R dielectric material and supports a current rating of 300 mA. It has a maximum DC resistance of 600 mOhms and operates within a temperature range of -55°C to +125°C. The package is a 1206 (3216 metric) footprint with four terminals.

Feature Summary

• Integrated feedthrough design combining filtering and decoupling functions in a single surface-mount package.
• High current handling capability suitable for power line noise suppression applications.
• Robust thermal stability provided by X7R dielectric across an extended industrial temperature range.

Applications

• Smart meter internal circuitry protection
• Industrial equipment signal line filtering
• Consumer electronics power input stages

Procurement Notes

Verify the specific suffix 'T3A' against official datasheets to confirm tape-and-reel packaging specifications. Ensure compatibility with standard reflow soldering profiles for 1206 components. Cross-reference terminal configurations to confirm four-terminal grounding requirements for optimal RF performance.

Selection Notes

Select this component when space-constrained designs require combined filtering and decoupling. The 1206 package offers a balance between capacitance density and board area. Verify that the 300 mA current rating meets the application's peak load requirements without exceeding thermal limits.

Part Context

This part belongs to the W3F series of multilayer ceramic surface-mount feedthrough filters. These components are engineered to replace traditional discrete filter capacitors, reducing component count and improving high-frequency performance through integrated ground paths.

Replacement Considerations

W3F15C1028AT1A is a parameter-equivalent alternative within the same series. Verify packaging differences as AT1A typically denotes cut-tape or Digi-Reel options compared to the reel configuration of AT3A.
