YFF21PC1A475MT000N

Overview

The TDK YFF21PC1A475MT000N is a commercial-grade three-terminal feedthrough capacitor designed for EMI suppression. It features a capacitance of 4.7 µF with a ±20% tolerance and a rated DC voltage of 10 V. The component utilizes an MLCC structure within a compact 0805 (2012 Metric) surface-mount package, measuring 2.0 mm in length, 1.25 mm in width, and 0.85 mm in height. It supports a maximum DC current of 3 A and exhibits a low impedance characteristic of 12 mΩ.

Feature Summary

• Three-terminal architecture provides effective high-frequency noise attenuation through direct ground connection.
• MLCC construction ensures stable performance in compact surface-mount applications.
• Low impedance design facilitates efficient signal integrity preservation in power lines.

Applications

• EMI filtering in portable electronic devices
• Noise suppression in automotive infotainment systems
• Power line conditioning in industrial control modules

Procurement Notes

Verify the specific suffix MT000N against the manufacturer's official datasheet to confirm packaging and tape-and-reel specifications. Ensure compatibility with standard 0805 footprint dimensions during PCB layout. Cross-reference the 10V rating and 4.7µF value with circuit requirements to prevent derating issues under operating conditions.

Selection Notes

Select this component when space-constrained designs require high capacitance density for EMI mitigation. The 0805 package offers a balance between electrical performance and board real estate. Consider the 3A current rating for power distribution networks where significant ripple currents are present alongside high-frequency noise.

Part Context

This part belongs to the TDK YFF series of commercial-grade feedthrough capacitors. These components are engineered to replace traditional discrete filter arrangements by integrating capacitance and grounding into a single SMD device. The series is widely used in consumer electronics and automotive sectors for compact noise reduction solutions.

Replacement Considerations

Direct substitutes include other 0805 three-terminal feedthrough capacitors with similar 4.7µF/10V ratings from manufacturers like Murata or Samsung Electro-Mechanics. Verify pinout compatibility and physical dimensions before substitution to ensure seamless integration without PCB redesign.
