NFM21PS106B0J3D

Overview

The NFM21PS106B0J3D is a three-terminal feedthrough capacitor from Murata Electronics, designed for high-performance EMI suppression in surface-mount applications. It features a capacitance of 10 µF with a ±20% tolerance and a DC voltage rating of 6.3 V. The component operates within a temperature range of -40°C to +85°C and has a maximum DC resistance of 10 mΩ. It supports a rated current of 4 A and is housed in an 0805 (2012 Metric) package measuring 2.0 mm x 1.25 mm x 0.95 mm.

Feature Summary

• Three-terminal feedthrough architecture provides superior high-frequency noise attenuation compared to standard two-terminal capacitors.
• Low equivalent series resistance (ESR) enables effective handling of high ripple currents without significant thermal rise.
• Compact 0805 footprint allows integration into space-constrained printed circuit board layouts.

Applications

• Power supply input filtering for portable electronic devices
• Noise suppression on data lines in mobile communication equipment
• EMI mitigation in automotive infotainment systems

Procurement Notes

Verify the specific suffix 'B0J3D' against official Murata documentation to confirm the exact termination plating and tape-and-reel specifications. Ensure that the 6.3V DC rating aligns with your circuit's peak operating voltage to prevent dielectric breakdown. Confirm RoHS compliance status if required by your manufacturing standards.

Selection Notes

Select this component when high capacitance density is required in an 0805 package for EMI filtering. The 4A current rating makes it suitable for power rail decoupling where low impedance is critical. Compare against the NFM21PC series if higher voltage ratings or different temperature characteristics are needed for the application environment.

Part Context

This part belongs to the Murata EMIFIL NFM21PS series, which specializes in three-terminal feedthrough capacitors. These components are engineered to minimize parasitic inductance, offering better high-frequency performance than conventional chip capacitors. The PS designation typically indicates specific internal electrode structures optimized for power line filtering.
