NFM21HC470U1H3D

Overview

The Murata NFM21HC470U1H3D is a three-terminal feed-through capacitor from the EMIFIL NFM21HC series. It features a capacitance of 47 pF with a tolerance of ±20%. The device has a DC voltage rating of 50 V and a rated current of 700 mA. It utilizes an SMD/SMT termination 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 operates within a temperature range of -55°C to +125°C and holds AEC-Q200 qualification.

Feature Summary

• Three-terminal architecture provides low impedance grounding for effective high-frequency noise suppression
• Feed-through design integrates filtering and decoupling functions within a compact surface-mount footprint
• AEC-Q200 qualified construction ensures reliability for automotive electronic applications

Applications

• Automotive electronics requiring EMI suppression
• High-frequency signal line filtering
• Power supply noise reduction in compact devices

Procurement Notes

Verify the specific suffix codes against official Murata documentation to confirm exact capacitance and tolerance values. Ensure the selected variant matches the required 50V DC rating and 700mA current handling capability for the target circuit. Confirm RoHS compliance status through the manufacturer's latest datasheet before finalizing procurement specifications.

Selection Notes

Select this component when space constraints require a 0805 footprint but higher current handling than standard capacitors allows. The three-terminal design is suitable for applications needing superior high-frequency attenuation compared to two-terminal alternatives. Verify that the operating temperature range meets the environmental requirements of the end-use equipment.

Part Context

This part belongs to the Murata EMIFIL NFM21HC series of three-terminal feed-through capacitors. These components are designed for high-current applications where traditional capacitors might fail due to thermal limitations. The series offers a balance of small size and robust performance for noise suppression in sensitive electronic circuits.

Replacement Considerations

Check for direct substitutes within the NFM21HC series with identical capacitance and package dimensions. Verify that any alternative maintains the same 700mA current rating and 50V DC voltage specification to ensure circuit compatibility.
