NFM3DCC220U1H3L

Overview

The Murata NFM3DCC220U1H3L is a surface-mount feedthrough capacitor from the EMIFIL NFM3 series, designed for high-frequency EMI suppression. It features a capacitance of 22 pF with a tolerance of -20% to +50%, rated for 50 VDC and a current rating of 300 mA. The component utilizes a 1205 (3212 metric) package with three terminals, measuring 3.20 mm in length, 1.25 mm in width, and a maximum height of 0.90 mm. It operates within a temperature range of -55°C to 125°C and meets AEC-Q200 automotive qualification standards.

Feature Summary

• Three-terminal feedthrough architecture provides superior high-frequency noise attenuation compared to standard two-terminal capacitors.
• Low equivalent series resistance (ESR) and inductance (ESL) enable effective electromagnetic interference suppression in compact designs.
• Automotive-grade reliability certified under AEC-Q200 standards for harsh environment durability.

Applications

• High-speed digital signal line filtering in automotive electronic control units
• Power supply input/output decoupling in mobile communication devices
• EMI suppression on USB, HDMI, and other high-bandwidth data interfaces

Procurement Notes

Verify the specific suffix 'U' against the manufacturer's latest datasheet, as it may indicate obsolete status or specific legacy packaging variations. Confirm RoHS compliance and REACH status directly with authorized distributors. Ensure the selected supplier provides valid traceability documentation for automotive-grade components. Cross-reference the MSL rating before storage and handling procedures.

Selection Notes

Select this component when space constraints require a 1205 footprint but higher performance than standard MLCCs is needed. The 22 pF value targets high-frequency noise above typical power-line frequencies. Consider the 300 mA current rating for power integrity applications. Evaluate the -20% to +50% tolerance if precise capacitance is critical for filter cutoff frequencies.
