W2F11A4718AT1A

Overview

The W2F11A4718AT1A is a surface-mount feedthrough capacitor from the KYOCERA AVX W2F series. It features a 470 pF capacitance with C0G (NP0) dielectric and a 100 VDC voltage rating. 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. Operating temperatures range from -55°C to +125°C, with a tolerance of -20% to +50%.

Feature Summary

• Low parallel inductance construction for effective high-frequency decoupling
• Feedthrough design providing superior electromagnetic interference filtering
• C0G (NP0) dielectric ensuring stable capacitance across temperature variations

Applications

• High-frequency circuit decoupling
• Electromagnetic interference suppression in sensitive electronics
• Power distribution networks requiring low impedance paths

Procurement Notes

Verify the specific suffix 'T1A' against official datasheets to confirm reel packaging specifications. Confirm RoHS compliance status through manufacturer documentation prior to integration. Ensure the 0805 footprint matches the target PCB layout dimensions precisely. Validate thermal performance within the specified -55°C to +125°C operating range for the intended application environment.

Selection Notes

Select this component when low parallel inductance is critical for high-speed signal integrity. The 0805 package offers a compact solution for space-constrained designs. The C0G dielectric provides minimal capacitance drift, suitable for precision timing or filtering applications. Consider the 300 mA current rating to ensure adequate power handling without excessive heating or resistance drop in the circuit path.

Part Context

This part belongs to the W2F series of surface-mount feedthrough filters. These components are engineered to replace traditional discrete capacitors by integrating the capacitor and ground connection into a single package. This integration significantly reduces parasitic inductance compared to standard MLCCs, enhancing high-frequency performance in noise-sensitive environments.
