NFM21PC225B0J3D

Overview

The NFM21PC225B0J3D is a three-terminal feedthrough capacitor manufactured by Murata Electronics, designed for high-performance electromagnetic interference (EMI) suppression in compact electronic assemblies. This component features a capacitance of 2.2 µF with a tolerance of ±20% and a DC voltage rating of 6.3 V. It operates within a temperature range of -40°C to +85°C and is housed in an 0805 (2012 metric) surface-mount package measuring 2.0 mm x 1.25 mm x 0.85 mm. The device supports a rated current of 4 A and exhibits a maximum DC resistance of 20 mΩ.

Feature Summary

• Three-terminal architecture provides superior high-frequency noise attenuation compared to standard two-terminal capacitors by minimizing parasitic inductance.
• Feedthrough design enables effective EMI filtering for sensitive signal lines and power distribution networks in dense circuit layouts.
• Capable of handling high ripple currents up to 4 A while maintaining low impedance characteristics for efficient noise dissipation.

Applications

• Noise suppression in mobile communication devices and smartphone power rails
• EMI filtering for USB interfaces and high-speed data transmission lines
• Power supply decoupling in automotive infotainment and control modules

Procurement Notes

Verify the specific suffix codes against official Murata documentation to ensure correct termination and packaging specifications. Confirm that the selected variant meets the required AEC-Q200 qualification if intended for automotive applications. Cross-reference the manufacturer part number with authorized distributor catalogs to avoid counterfeit components and ensure traceability.

Selection Notes

Select this component when space-constrained designs require high capacitance values with minimal parasitic inductance. The 0805 footprint allows for direct replacement of larger through-hole or multi-layer ceramic capacitors where board real estate is limited. Ensure the operating voltage remains below the 6.3 V DC rating to maintain reliability under dynamic load conditions.

Part Context

This component belongs to the Murata EMIFIL® NFM21P series of three-terminal feedthrough capacitors. The series is engineered for applications demanding robust EMI suppression in small form factors. The NFM21PC225B0J3D specifically utilizes a barium titanate dielectric to achieve its 2.2 µF value within the 0805 case size, balancing electrical performance with physical compactness for modern electronics.

Replacement Considerations

Direct substitutes include other Murata NFM21PC series variants with matching capacitance and voltage ratings, such as NFM21PC225B0J3D-ND equivalents from authorized distributors. Verify pinout compatibility and thermal characteristics before integrating alternative brands.
