NFM21CC221R1H3D

Overview

The Murata NFM21CC221R1H3D is a three-terminal feedthrough capacitor from the EMIFIL NFM21C series. It features a capacitance of 220 pF with a tolerance of ±20%. The device has a DC voltage rating of 50V and operates within a temperature range of -55°C to +125°C. It utilizes an SMD/SMT mounting type in a 0805 (2012 metric) package, measuring 2 mm in length, 1.25 mm in width, and 0.85 mm in height. The component includes a ground terminal of 0.6 mm and carries AEC-Q200 qualification.

Feature Summary

• Three-terminal structure providing low impedance grounding for effective EMI suppression
• Feedthrough design enabling high-frequency noise filtering in compact spaces
• AEC-Q200 qualified for automotive reliability standards

Applications

• Automotive electronic systems requiring EMI filtering
• High-frequency signal line noise suppression
• Power supply input/output filtering in compact devices

Procurement Notes

Verify the complete part number including suffixes against official Murata documentation to ensure correct capacitance, tolerance, and termination specifications. Confirm RoHS compliance status and specific packaging options such as reel or cut tape availability through authorized distributors. Check for any regional distribution restrictions or obsolescence notices prior to procurement.

Selection Notes

Select this component when a 220 pF capacitance value is required for high-frequency noise attenuation in space-constrained designs. The 0805 footprint allows for standard surface mount assembly processes. Ensure the 50V DC rating meets the circuit's operating voltage requirements and that the -55°C to +125°C temperature range aligns with the environmental conditions of the target application.

Part Context

This component belongs to the Murata EMIFIL NFM21C series of three-terminal feedthrough capacitors. These components are designed to replace traditional two-terminal capacitors by providing a direct ground path, thereby reducing parasitic inductance and improving high-frequency performance. The series is widely used in applications demanding robust electromagnetic interference suppression.

Replacement Considerations

Direct substitutes include other Murata NFM21C series parts with identical 220 pF capacitance and 0805 footprint, such as NFM21CC221U1H3D if tolerance variations are acceptable. Cross-brand replacements must match the 220 pF value, 50V rating, 0805 dimensions, and three-terminal configuration to maintain circuit integrity.
