Overview
The NFM21HC101U1H3D is a three-terminal feed-through capacitor from the Murata EMIFIL NFM21HC series. It features a capacitance of 100 pF with a tolerance of ±20%. The component has a DC voltage rating of 50 V and a rated current of 700 mA. It utilizes an SMD/SMT termination type within a 0805 (2012 metric) package, measuring 2 mm in length, 1.25 mm in width, and 0.85 mm in height. The device operates between -55°C and +125°C, holds AEC-Q200 qualification, and exhibits an insulation resistance of 1 GOhms.
Feature Summary
- Three-terminal architecture provides superior high-frequency noise suppression compared to standard two-terminal capacitors.
- AEC-Q200 qualified for automotive electronic applications requiring robust reliability.
- Compact 0805 surface-mount footprint designed for space-constrained circuit board layouts.
Applications
- Automotive infotainment system power line filtering
- Noise suppression on high-speed data interfaces
- EMI/RFI mitigation in compact electronic modules
Procurement Notes
Verify the specific suffix U1 against official Murata documentation to confirm pin configuration and terminal orientation. Ensure the selected variant matches the required 700 mA current rating for the target application. Confirm RoHS compliance status through the manufacturer's latest datasheet before finalizing procurement specifications.
Selection Notes
Select this component when high-frequency attenuation is critical in limited space. The three-terminal design offers lower parasitic inductance than standard capacitors. Verify that the 50 VDC rating and 700 mA current capacity align with the circuit requirements. Consider the AEC-Q200 qualification if the application demands automotive-grade reliability standards.
Part Context
This part belongs to the NFM21HC series, which represents Murata's automotive-grade feed-through capacitors. The series is engineered for effective EMI suppression in demanding environments. The HC designation indicates specific performance characteristics tailored for automotive electronics, distinguishing it from general-purpose industrial variants within the broader NFM family.
Replacement Considerations
NFM21CC101U1H3D serves as a potential substitute but lacks AEC-Q200 automotive qualification. Verify that the non-automotive grade meets all environmental and reliability requirements for the intended use case before implementation.
