NFM21HC220U1H3D

Overview

The Murata NFM21HC220U1H3D is a surface-mount feed-through capacitor from the EMIFIL NFM21HC series. It features a capacitance of 22 pF with a tolerance of ±20% and a DC voltage rating of 50 V. The component utilizes a three-terminal design in an 0805 (2012 metric) package, measuring 2.0 mm x 1.25 mm x 0.85 mm. It supports a current rating of 300 mA and operates within a temperature range of -55°C to +125°C. Certified under AEC-Q200 for automotive reliability, it offers high insulation resistance of 1 GOhms.

Feature Summary

• Three-terminal feed-through architecture provides effective EMI/RFI filtering by minimizing parasitic inductance.

Applications

• Automotive electronic circuits requiring AEC-Q200 certified components

Procurement Notes

Verify the specific suffix 'U' against official Murata documentation to confirm material composition or termination specifications. Ensure the selected variant matches the required 50V DC rating and 22pF capacitance for the target application. Cross-reference the 0805 footprint dimensions during PCB layout validation.

Selection Notes

Select this component when compact EMI suppression is needed in space-constrained automotive designs. The 0805 form factor allows for dense mounting while maintaining the electrical performance of a feed-through topology. Consider the 300mA current handling capability relative to the circuit's operational load requirements.

Part Context
