W3H15C4738AT1F

Overview

The W3H15C4738AT1F is a surface-mount feedthrough capacitor from the KYOCERA AVX W3H series. It features a capacitance of 0.047 µF with a DC voltage rating of 50 VDC and an X7R dielectric. The component operates within a temperature range of -55°C to +125°C and has a maximum DC resistance of 150 mOhms. It utilizes a 0612 (1632 metric) package with four terminals and carries AEC-Q200 qualification.

Feature Summary

• AEC-Q200 qualified for automotive reliability standards
• High current handling capability up to 5 A
• Low impedance design with 150 mOhms maximum DCR
• Compact 0612 surface-mount footprint

Applications

• Automotive power distribution networks
• 48V vehicle electrical systems
• Load dump protection circuits
• High-current signal filtering

Procurement Notes

Verify the specific suffix 'T1F' against official datasheets to confirm the 0612 package and 5 A rating, as variations exist within the W3H family. Ensure the application environment remains within the specified -55°C to +125°C operating range. Confirm AEC-Q200 compliance requirements are met for automotive integration.

Selection Notes

Select this component when high current capacity and low inductance are required in a compact form factor. The 0612 package offers higher current handling than smaller 0805 variants. Verify that the 50 VDC rating accommodates system transients, particularly in 48V automotive architectures where load dump events may exceed nominal voltages.

Part Context

This part belongs to the W3H Auto series, designed specifically for automotive applications requiring robust performance under harsh conditions. It serves as a high-current alternative to standard feedthrough capacitors, providing effective EMI suppression while maintaining low series resistance for efficient power delivery.

Replacement Considerations

W3H15C4738AT1A is a parameter-equivalent substitute within the same series.
