Overview
The Murata NFM21CC223R1H3D is a three-terminal feedthrough capacitor from the EMIFIL NFM21C series. It features a capacitance of 0.022 µF with a tolerance of ±20%. The device is rated for a DC voltage of 50V and supports a current rating of 2A. Designed for surface mount installation, it utilizes an 0805 (2012 Metric) package with dimensions of 2.00mm length, 1.25mm width, and a maximum height of 0.95mm. The component operates within a temperature range of -55°C to +125°C.
Feature Summary
- Three-terminal architecture reduces residual inductance to extremely low levels for effective high-frequency noise suppression.
- Feedthrough design provides superior EMI filtering performance compared to standard two-terminal capacitors.
- Surface mount construction allows for compact integration into dense PCB layouts.
Applications
- High-speed digital circuit signal line filtering
- Power supply input/output decoupling
- EMI suppression in communication equipment
Procurement Notes
Verify the complete part number including suffixes against official Murata documentation to ensure correct voltage, capacitance, and termination specifications. Confirm RoHS compliance status and moisture sensitivity level requirements prior to ordering. Cross-reference manufacturer datasheets for accurate handling and reflow soldering profiles specific to this component variant.
Selection Notes
Select this component when low parasitic inductance is critical for EMI mitigation in high-current applications. The 0805 footprint offers a balance between size and power handling capability. Ensure the operating voltage does not exceed 50VDC and that the expected ripple current remains within the 2A limit. Consider thermal management capabilities within the specified -55°C to +125°C range during design integration.
Part Context
This component belongs to the Murata EMIFIL NFM21C series of three-terminal feedthrough capacitors. These devices are engineered for high-performance electromagnetic interference suppression in compact electronic systems. The series is characterized by its ability to maintain stable electrical properties across wide temperature ranges while providing effective noise attenuation in both power and signal lines.
Replacement Considerations
Direct substitutes within the same series include NFM21CC471R1H3D and NFM21CC102R1H3D, though these differ in capacitance values. Verify pin compatibility and electrical ratings before substituting any alternative components.
