NFL18ST207H1A3D

Overview

The NFL18ST207H1A3D is a surface-mount LC (T-type) EMI filter from Murata Electronics, designed for noise suppression in compact electronic circuits. It features a third-order low-pass configuration with an inductance of 110 nH and capacitance of 25 µF. The component operates within a voltage rating of 16 V and a current capacity of 150 mA. Its physical dimensions are 1.6 mm x 0.8 mm x 0.8 mm in a 0603 package. The device supports a wide operating temperature range from -55°C to +125°C and offers a cutoff frequency of 200 MHz.

Feature Summary

• Delivers steep insertion loss characteristics for excellent noise suppression while preventing signal waveform distortion.
• Utilizes a T-type LC circuit topology to achieve high-performance filtering in a minimal footprint.
• Provides robust thermal stability across an extended industrial temperature range.

Applications

• Noise reduction in clock lines
• Signal integrity protection in video lines
• Data line filtering in portable devices

Procurement Notes

Verify the specific suffix H1A3D against the official Murata part numbering guide to ensure correct component specifications. Confirm that the required capacitance value aligns with system design requirements before procurement. Check for any recent product change notifications or end-of-life status updates directly from the manufacturer. Ensure compatibility with standard surface-mount assembly processes.

Selection Notes

Select this component when space constraints require a 0603 footprint but high attenuation is necessary. Consider the 25 µF capacitance value for effective low-frequency noise filtering. Evaluate the 16 V rating against peak signal voltages to prevent breakdown. Compare performance against standard RC filters if signal distortion tolerance is critical.

Part Context

This component belongs to the NFL series of EMIFIL products by Murata Electronics. The series focuses on providing high-density EMI suppression solutions for modern electronics. The NFL18ST variant specifically targets applications requiring steep roll-off characteristics in small packages.
