NFM41CC471R2A3L

Overview

The Murata NFM41CC471R2A3L is a surface-mount feedthrough capacitor from the NFM41C series. It features a capacitance of 470 pF with a tolerance of -20% to +50%. The component has a rated DC voltage of 100V and a maximum current rating of 300 mA. Its DC resistance (DCR) is 300 mΩ. The device operates within a temperature range of -55°C to 125°C. It utilizes a 1806 (4516 Metric) package with three PCB pads, measuring 4.50 mm in length, 1.60 mm in width, and 1.20 mm in height.

Feature Summary

• Feedthrough design providing low impedance path for high-frequency noise suppression
• Surface mount construction compatible with automated assembly processes
• Three-pad terminal configuration for enhanced grounding and signal integrity

Applications

• Power supply line filtering in electronic devices
• EMI suppression in high-speed digital circuits
• Signal conditioning in communication equipment

Procurement Notes

Verify the specific capacitance value and tolerance against project requirements, as the suffix indicates 470 pF. Confirm that the 300 mA current rating and 100 V voltage rating meet the circuit's operational limits. Ensure the 1806 footprint matches the PCB layout. Check RoHS compliance status if required by regulatory standards.

Selection Notes

Select this component when a compact feedthrough capacitor is needed for EMI filtering on power or signal lines. The 1806 package offers a balance between size and performance. Consider the -20% to +50% tolerance if precise capacitance is not critical. The low DCR ensures minimal voltage drop under load.

Part Context

This part belongs to the Murata EMIFIL NFM41C series of feedthrough capacitors. These components are designed for effective noise reduction in space-constrained applications. The series is known for its reliability and consistent performance across a wide temperature range, making it suitable for industrial and consumer electronics.

Replacement Considerations

Check for direct substitutes within the NFM41C series with different capacitance values if filtering requirements change. Verify pinout compatibility before replacing with other feedthrough capacitor brands.
