NFA18SL307V1A45L

Overview

The NFA18SL307V1A45L is a surface-mount LC combined EMI filter from the Murata NFA18SL series, designed for noise suppression at 300 MHz. It features a steep and deep insertion loss curve within an ultra-compact 0603 (1.6 x 0.8 x 0.5 mm) package. The component operates across a frequency range of 800 MHz to 900 MHz with 20 dB attenuation. It supports temperatures from -55°C to 125°C and has a rated voltage of 10V.

Feature Summary

• LC combined array design providing steep and deep insertion loss characteristics
• Ultra-compact 0603 footprint suitable for space-constrained layouts
• Optimized for high-frequency noise suppression applications

Applications

• General electronic noise suppression
• Mobile device signal line filtering
• Portable equipment EMI mitigation

Procurement Notes

This component is scheduled for obsolescence and will be discontinued by the manufacturer. Verify current availability status through authorized distributors before finalizing procurement plans. Due to the end-of-life status, long-term supply cannot be guaranteed. Consider alternative sourcing strategies or transition planning immediately to mitigate production risks associated with this discontinued part number.

Selection Notes

Select this component only if the specific 300 MHz optimization and 0603 form factor are required. Note that the NFA18SL series offers compact size and steep attenuation curves. Ensure the application environment stays within the -55°C to 125°C operating temperature range. Verify that the 10V rating meets circuit requirements. Given the discontinuation status, evaluate replacement options early in the design phase.

Part Context

Part of the Murata NFA18SL series, which utilizes LC combined technology for effective EMI filtering. The series is characterized by its small physical dimensions and high-performance attenuation profiles. This specific model targets noise control in modern portable electronics where board space is limited. The array configuration allows for multi-line filtering in a single package.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the scheduled obsolescence, direct replacements should be identified through Murata's official obsolescence notices or equivalent series components with matching electrical specifications and footprint compatibility.
