W2F15C4728AT1B

Overview

The KYOCERA AVX W2F15C4728AT1B is a surface-mount feedthrough capacitor with a capacitance of 4700 pF and a DC voltage rating of 50 V. It utilizes X7R dielectric material and features a four-terminal SMD package in the 0805 (2012 metric) footprint, measuring 2.01 mm in length, 1.25 mm in width, and 1.14 mm in height. The component 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%. It functions as a three-terminal filter capacitor effective across a frequency range of 0 Hz to 5 GHz.

Feature Summary

• Provides EMI/RFI noise suppression through integrated feedthrough filtering architecture
• Supports high-current applications via a 300 mA rated ground terminal design
• Enables compact circuit board layout using a standard 0805 surface-mount footprint

Applications

• EMI/RFI noise suppression in electronic circuits
• Power line filtering for signal integrity
• Smart meter internal circuitry protection

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm exact electrical tolerances and packaging configurations. Ensure the selected variant matches the required capacitance tolerance and termination style for the target PCB assembly. Cross-reference datasheet revisions to validate compliance with current environmental standards such as RoHS before finalizing procurement orders.

Selection Notes

Select this component when space-constrained designs require effective high-frequency noise attenuation without sacrificing current handling capabilities. The 0805 form factor allows for dense placement on printed circuit boards while maintaining robust thermal performance within the specified operating temperature range. Evaluate the low DC resistance requirement to ensure minimal voltage drop across the filtered power lines during operation.

Part Context

This component belongs to the W2F series of surface-mount feedthrough capacitors manufactured by KYOCERA AVX. The series is engineered to provide superior electromagnetic interference suppression compared to standard multilayer ceramic capacitors. These devices integrate filtering functionality directly into the passive component structure, simplifying circuit design and reducing the overall component count required for noise mitigation strategies.
