W2H15C1028AT1A

Overview

The W2H15C1028AT1A is a surface-mount feedthrough capacitor manufactured by KYOCERA AVX. It features a capacitance of 1000 pF with an X7R dielectric material, providing stable performance across a temperature range of -55°C to +125°C. The component is rated for 50 VDC and supports a current handling capacity of 1 A. It utilizes a 0805 (2012 metric) package with four terminal pads. Key electrical characteristics include a maximum DC resistance of 150 mOhms and a tolerance of -20% to +50%. The device is designed for high-frequency noise suppression in compact electronic circuits.

Feature Summary

• Integrates three-terminal feedthrough architecture for effective electromagnetic interference filtering within a compact surface-mount footprint.
• Utilizes X7R ceramic dielectric to maintain capacitance stability under varying thermal conditions and voltage stress.
• Supports high-current signal paths with low DC resistance, minimizing insertion loss in power and data lines.

Applications

• High-speed digital interface noise suppression
• RF circuit grounding and decoupling
• Automotive electronics EMI filtering

Procurement Notes

Verify the specific suffix 'AT1A' against the manufacturer's official datasheet to confirm terminal configuration and termination plating specifications. Ensure that the 0805 package dimensions align with the target PCB land pattern design. Confirm RoHS compliance status through the latest product documentation before integration into regulated assemblies.

Selection Notes

Select this component when space-constrained designs require integrated filtering without additional discrete inductors. The 1 A current rating makes it suitable for power line applications where low impedance is critical. Compare the 150 mOhm DCR against system requirements to ensure minimal voltage drop. Consider the X7R temperature coefficient if operating environments exceed standard commercial ranges.

Part Context

This part belongs to the W2H series of surface-mount feedthrough capacitors from KYOCERA AVX. The series is engineered for high-frequency noise attenuation in portable and automotive electronics. The W2H variant specifically offers enhanced current handling compared to lower-rated counterparts, supporting robust performance in demanding signal integrity applications.

Replacement Considerations

Cross-reference with W2F15C1028AT1A for similar capacitance but note the significant difference in current rating (300 mA vs 1 A). Verify pinout compatibility with W3F15C1028AT1A, although the latter uses a larger 1206 package. Consult manufacturer substitution guides for exact functional equivalents.
