W2F15C1038AT1A

Overview

The W2F15C1038AT1A is a surface-mount feedthrough capacitor from the KYOCERA AVX W2F series. It features a capacitance of 10 nF with X7R dielectric characteristics and a DC voltage rating of 50 VDC. The component utilizes a 0805 (2012 metric) package with four terminals, measuring 2.01 mm in length, 1.25 mm in width, and 1.14 mm in height. It supports a current rating of 300 mA and has a maximum DC resistance of 600 mOhms. The unit operates within a temperature range of -55°C to +125°C.

Feature Summary

• Provides electromagnetic interference filtering through integrated three-terminal feedthrough architecture
• Utilizes X7R ceramic dielectric for stable capacitance performance across operating temperatures
• Features a compact 0805 surface-mount footprint designed for high-density PCB layouts

Applications

• Smart meter circuitry requiring EMI suppression
• Power supply input/output filtering stages
• Signal line protection in industrial control systems

Procurement Notes

Verify the complete part number including suffixes to ensure correct packaging and tolerance specifications. Confirm RoHS compliance status and moisture sensitivity level requirements against project standards. Cross-reference manufacturer datasheets for specific handling and reflow soldering profiles to maintain component integrity during assembly processes.

Selection Notes

Select this component when a low-profile, high-current feedthrough filter is required for 50V applications. The 0805 package size offers a balance between thermal performance and board space efficiency. Ensure the X7R temperature coefficient aligns with the operational environment, as capacitance may vary significantly outside nominal conditions compared to NP0 types.

Part Context

This component belongs to the W2F series of surface-mount feedthrough capacitors manufactured by KYOCERA AVX. These devices are engineered to replace traditional discrete filter components, offering superior high-frequency attenuation in a small form factor. The series is commonly utilized in automotive and industrial electronics where reliable noise suppression is critical.

Replacement Considerations

Direct substitutes include other W2F series variants with matching capacitance and voltage ratings, such as W2F15C1038BT1A for tighter tolerances. Verify pinout compatibility and physical dimensions before integrating alternative manufacturers' equivalent parts into existing designs.
