W2F15C1028AT1A

Overview

The KYOCERA AVX W2F15C1028AT1A is a surface-mount feedthrough capacitor from the W2F series, housed in an 0805 (2012 metric) package. It features a capacitance of 1000 pF with X7R dielectric and a DC voltage rating of 50 VDC. The component has a current rating of 300 mA and a maximum DC resistance of 600 mOhms. Tolerance is specified as -20% to +50%. It operates within a temperature range of -55°C to +125°C and utilizes a four-terminal SMD/SMT configuration.

Feature Summary

• Provides integrated filtering and decoupling through a three-terminal feedthrough architecture
• Utilizes X7R ceramic dielectric for stable capacitance performance across operating temperatures
• Designed for high-current signal paths with low DC resistance characteristics

Applications

• High-frequency noise suppression in RF circuits
• Power line filtering for sensitive electronic components
• EMI/RFI mitigation in compact surface-mount designs

Procurement Notes

Verify the specific suffix 'AT1A' against the manufacturer's latest datasheet to confirm tape-and-reel packaging specifications and terminal plating details. Ensure the 0805 footprint matches the target PCB layout, noting the four-pad configuration required for proper grounding and signal routing. Cross-reference RoHS3 compliance status if environmental regulations apply to the final assembly.

Selection Notes

Select this component when space-constrained applications require combined filtering and decoupling functions. The 0805 case size offers a balance between parasitic inductance reduction and board area efficiency. Consider the 300 mA current rating and 600 mOhm DCR limits to ensure the component can handle the intended signal or power load without excessive thermal generation or voltage drop.

Part Context

This part belongs to the KYOCERA AVX W2F series of multilayer ceramic feedthrough capacitors. These components are engineered to replace traditional discrete filter networks by integrating capacitor and ground plane functions into a single surface-mount device. The series is designed for applications requiring effective high-frequency noise attenuation in minimal footprints.

Replacement Considerations

Direct substitutes include other 0805 feedthrough capacitors with similar 1000 pF capacitance and 50 V ratings, such as the W3F15C1028AT1A, though the latter uses a larger 1206 package. Verify pinout compatibility and electrical parameters before substituting.
