NFL18ZT507H1A3D

Overview

The NFL18ZT507H1A3D is a third-order LC (T-type) EMI filter circuit manufactured by Murata Electronics. It features a cutoff frequency of 50 MHz, with an inductance of 350 nH and capacitance of 110 pF. The component supports a maximum voltage rating of 10 V and a current rating of 75 mA. It utilizes SMD/SMT termination and is housed in a 0603 (1608 metric) package measuring 1.6 mm x 0.8 mm x 0.6 mm. The device operates within a temperature range of -55°C to +125°C and holds AEC-Q200 qualification.

Feature Summary

• Third-order LC T-type topology for enhanced signal line filtering
• AEC-Q200 qualified for automotive reliability standards
• Compact 0603 surface-mount footprint for space-constrained designs

Applications

• Automotive infotainment system clock lines
• Video signal line EMI suppression
• General-purpose signal line filtering in electronic circuits

Procurement Notes

Verify the specific suffix H1A3D against official Murata documentation to confirm exact electrical tolerances and termination specifications. Confirm availability status as distribution data may indicate end-of-life or limited stock conditions. Ensure the procurement channel provides valid traceability for AEC-Q200 certified components required for automotive applications.

Selection Notes

Select this component when a third-order low-pass response is required for high-frequency noise attenuation on sensitive signal lines. The 10 V rating and 75 mA current limit define the operational boundaries; ensure circuit conditions remain within these parameters. The AEC-Q200 qualification makes it suitable for automotive environments where thermal stability from -55°C to +125°C is mandatory.

Part Context

This part belongs to the Murata NFL series of EMIFIL filters, specifically designed for EMI suppression. The NFL18ZT variant denotes a specific impedance and configuration within the family, optimized for compact PCB layouts. It serves as a passive component alternative to active filtering solutions in high-noise environments.

Replacement Considerations

Consult official Murata substitution guides for direct equivalents. Verify that any substitute maintains the 350 nH inductance and 110 pF capacitance values to preserve the 50 MHz cutoff characteristic. Ensure the replacement also meets AEC-Q200 requirements if used in automotive contexts.
