W3F15C4728AT1A

Overview

The W3F15C4728AT1A is a surface-mount feedthrough capacitor from the KYOCERA AVX W3F series. It features a capacitance of 4700 pF with a DC voltage rating of 50 VDC and an X7R temperature coefficient. 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 current rating of 300 mA and has a maximum DC resistance of 600 milliohms. Tolerance is specified as -20% to +50%. Operating temperatures range from -55°C to 125°C.

Feature Summary

• Three-terminal feedthrough design for effective electromagnetic interference suppression
• Surface-mount construction compatible with automated assembly processes
• High current handling capability suitable for power line filtering applications

Applications

• Smart meter internal circuitry protection
• Alternate energy system power conditioning
• General purpose EMI filtering in compact electronic devices

Procurement Notes

Verify the specific ordering suffix against official datasheets to ensure correct packaging configuration. Confirm RoHS compliance status and moisture sensitivity level requirements prior to integration into production workflows. Cross-reference terminal counts and physical dimensions with PCB footprint specifications to prevent mounting errors during assembly.

Selection Notes

Select this component when space-constrained designs require high-performance EMI filtering in a standard 1206 footprint. The X7R dielectric provides stable capacitance across the specified industrial temperature range. Ensure the 50V DC rating exceeds the maximum operating voltage of the target circuit to maintain reliability and prevent dielectric breakdown under transient conditions.

Part Context

This part belongs to the W3F series of surface-mount feedthrough capacitors manufactured by KYOCERA AVX. The series is designed to replace traditional through-hole components in modern electronics manufacturing. These filters integrate capacitor and ground plane functions into a single compact package, reducing parasitic inductance compared to discrete solutions.
