NFL18ST507H1A3D

Overview

The NFL18ST507H1A3D is a surface-mount EMI filter circuit manufactured by Murata Electronics. It utilizes LC (T-Type) technology to provide low-pass filtering characteristics with a cutoff frequency of 500 MHz. The component features an inductance of 42 nH and a capacitance of 10 pF. It is rated for a maximum voltage of 10 V and a current of 100 mA. The device is housed in a compact 0603 (1608 metric) package, measuring 1.6 mm in length, 0.8 mm in width, and 0.6 mm in height. It operates within a temperature range of -55°C to +125°C.

Feature Summary

• Delivers sharp roll-off performance for effective electromagnetic interference suppression
• Utilizes LC T-type topology for signal line filtering applications
• Designed for surface-mount assembly in compact electronic devices

Applications

• Signal line filtering in portable electronics
• EMI suppression in mobile communication devices
• Noise reduction in high-speed data lines

Procurement Notes

Verify the specific suffix H1A3D against official Murata documentation to confirm exact electrical tolerances and termination specifications. Confirm availability status as distribution channels may list this part as obsolete or end-of-life. Ensure the selected variant matches the required 0603 footprint and thermal ratings for the target application environment before finalizing procurement orders.

Selection Notes

Select this component when a low-inductance, low-capacitance filter is required for high-frequency noise attenuation up to 500 MHz. The 10 V rating limits suitability to low-voltage logic interfaces. Compare against other NFL series variants if higher current handling or different cutoff frequencies are necessary. Ensure PCB layout accommodates the 0603 dimensions and thermal dissipation requirements for continuous operation at elevated temperatures.

Part Context

This component belongs to the Murata EMIFIL NFL series, which specializes in miniature EMI filters for consumer and industrial electronics. The NFL series is characterized by its small form factor and ability to integrate directly into tight spaces on printed circuit boards. This specific model represents a standard low-pass configuration within that product family.
