YFF18PW0J474MT0H0N

Overview

The TDK YFF18PW0J474MT0H0N is a three-terminal EMI feedthrough filter capacitor in a 0603 (1.6mm x 0.8mm) surface-mount package. It features a capacitance of 0.47 µF with ±20% tolerance and a voltage rating of 6.3 V DC. The component supports a maximum DC current of 4 A and has a maximum DC resistance of 30 mOhms. Operating temperature ranges from -55°C to +125°C. The physical dimensions are 1.60 mm length, 0.80 mm width, and 0.60 mm height.

Feature Summary

• Utilizes a feed-through structure that allows direct DC current passage while filtering noise.
• Shortened grounding distance reduces equivalent series inductance (ESL).
• Parallel ground electrode configuration enhances high-frequency noise suppression.

Applications

• Automotive general electronic circuits
• Power line filtering applications
• High-density PCB designs requiring low ESL

Procurement Notes

Verify the specific suffix 'PW' against official TDK documentation to confirm the exact dielectric material and commercial grade classification. Confirm RoHS compliance status directly with the manufacturer or authorized distributors prior to procurement. Ensure the selected packaging format matches production requirements.

Selection Notes

Select this component for applications requiring high ripple current handling in compact spaces. The 0603 footprint suits dense layouts. Verify that the 6.3V rating meets circuit voltage headroom requirements. Consider the 4A DC current capability for power rail decoupling needs.

Part Context

This part belongs to the TDK YFF-PW series of three-terminal feedthrough filters. These components are designed to replace standard MLCCs in noise-sensitive environments by providing superior high-frequency attenuation due to their unique internal electrode structure.

Replacement Considerations

Check TDK datasheets for alternative parts within the YFF-P series with matching capacitance and voltage ratings. Verify pin compatibility and thermal characteristics before substituting.
