NFE61HT181C2A9L

Overview

The Murata NFE61HT181C2A9L is a three-terminal feed-through capacitor from the EMIFIL NFE61HT series. It features an LC (T-type) circuit configuration with a capacitance of 180 pF and a rated DC voltage of 100 VDC. The component supports a current rating of 2 A and offers a tolerance of ±20%. Designed for surface mount installation, it utilizes a 2706 (6816 metric) package measuring 6.8 mm in length, 1.6 mm in width, and 1.9 mm in height. It operates within a temperature range of -55°C to +125°C and holds AEC-Q200 qualification.

Feature Summary

• Provides third-order low-pass filtering using an LC (T-type) circuit topology to attenuate electromagnetic interference.
• Features a three-terminal design that minimizes parasitic inductance for effective high-frequency noise suppression.
• Constructed as a combined type integrating feed-through capacitor and ferrite bead functions.

Applications

• Automotive electronic systems requiring AEC-Q200 qualified components
• Power line filtering in compact electronic devices
• High-density PCB layouts necessitating small footprint EMI suppression

Procurement Notes

Verify the specific suffix codes against official Murata documentation to confirm exact capacitance, voltage, and termination specifications. Ensure compatibility with the target application's thermal environment, noting the -55°C to +125°C operating range. Confirm RoHS compliance status and SVHC declarations prior to integration into final assemblies.

Selection Notes

Select this component when a third-order low-pass filter is required in a constrained space. The 180 pF capacitance and 100 VDC rating suit applications needing moderate filtering with high voltage resilience. The 2 A current rating allows use in power lines, while the T-type structure provides superior attenuation compared to standard two-terminal capacitors.

Part Context

This part belongs to the Murata EMIFIL NFE61HT series, which specializes in chip EMI filters.
