W3F15C4738AT1A

Overview

The W3F15C4738AT1A is a surface-mount feedthrough capacitor manufactured by KYOCERA AVX. It features a capacitance of 0.047 µF (47 nF) with a DC voltage rating of 50 V. The component utilizes X7R dielectric material and offers a tolerance range of -20% to +50%. Designed for the 1206 (3216 metric) package, it measures 3.2 mm in length, 1.6 mm in width, and 1.27 mm in height. The device supports a rated current of 300 mA and has a maximum DC resistance of 600 mOhms. It operates within a temperature range of -55°C to +125°C.

Feature Summary

• Utilizes a unique feedthrough capacitor structure to provide low parallel inductance for effective high-frequency noise suppression.
• Designed as a three-terminal filter capacitor suitable for EMI suppression and broadband I/O filtering applications.
• Constructed with X7R dielectric material to maintain stability across a wide operating temperature range.

Applications

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

Procurement Notes

Verify the specific suffix 'T1A' against official datasheets to confirm packaging and tape specifications. Ensure compatibility with RoHS3 standards if required by project constraints. Cross-reference terminal counts and physical dimensions during PCB layout finalization to prevent mounting errors.

Selection Notes

Select this component when low parasitic inductance is critical for high-frequency performance. The 1206 footprint offers a balance between current handling and board space. Consider the -20% to +50% tolerance if precise capacitance values are not strictly required for the filtering application.

Part Context

This part belongs to the W3F series of surface-mount feedthrough filters from KYOCERA AVX. These components are engineered to replace traditional discrete LC filters by integrating filtering capabilities into a single compact package, simplifying circuit design and reducing overall component count.

Replacement Considerations

W3F15C4738AT1F is listed as a parameter-equivalent substitute by the manufacturer.
