W3F15C1028AT1A

Overview

The W3F15C1028AT1A is a surface-mount feedthrough capacitor from the KYOCERA AVX W3F series. It features a 1000 pF capacitance with X7R dielectric and a 50 VDC voltage rating. The component utilizes a 1206 (3216 metric) package with four terminals, measuring 3.2 mm in length, 1.6 mm in width, and 1.27 mm in height. It supports a maximum current of 300 mA and has a maximum DC resistance of 600 mOhms. Operating temperatures range from -55°C to +125°C.

Feature Summary

• Provides EMI suppression through three-terminal feedthrough filter architecture
• Designed for broadband I/O filtering and power line conditioning applications
• Constructed with X7R ceramic dielectric for stable performance across temperature ranges

Applications

• EMI suppression circuits
• Broadband I/O filtering
• Vcc power line conditioning

Procurement Notes

Verify the specific suffix AT1A against official datasheets to confirm packaging type and terminal plating specifications. Ensure compatibility with RoHS3 compliance requirements if mandated by the target assembly standards. Cross-reference the manufacturer part number directly with KYOCERA AVX documentation to validate electrical parameters before procurement.

Selection Notes

Select this component when space-constrained designs require effective high-frequency noise attenuation in surface-mount layouts. The 1206 footprint offers a balance between capacitance density and thermal management capabilities. Consider the 300 mA current rating and low DCR for power integrity in sensitive signal paths requiring robust common-mode noise rejection.

Part Context

This component belongs to the W3F series of surface mount feedthrough filters manufactured by KYOCERA AVX. These devices are engineered to replace traditional discrete filter components, offering a compact solution for integrating filtering directly into circuit board layouts while maintaining reliable electrical performance under varying environmental conditions.
