NFA21SL207X1A45L

Overview

The NFA21SL207X1A45L is a second-order LC EMI filter array manufactured by Murata Electronics. It features four channels with a cutoff frequency of 200 MHz and provides 13 dB attenuation at 500 MHz. The component supports a maximum current of 100 mA and operates within a temperature range of -55°C to +125°C. It is housed in an 0805 (2012 metric) surface-mount package with dimensions of 2.00 mm x 1.25 mm x 0.60 mm. The device is classified as end-of-life.

Feature Summary

• Second-order low-pass LC filtering architecture for high-frequency noise suppression
• Quad-channel configuration integrated into a compact surface-mount footprint
• Designed for data line protection in mobile devices

Applications

• Mobile device data lines
• High-frequency noise suppression in compact electronic circuits

Procurement Notes

This component is designated as End of Life (EOL) and scheduled for obsolescence by the manufacturer. Verification of final shipment dates and availability through authorized distributors is required before integration into new designs. Engineers should confirm specific lifecycle status documentation directly with Murata Electronics or certified suppliers to ensure compliance with project timelines.

Selection Notes

Designers must account for the 100 mA current rating and 200 MHz cutoff frequency when selecting this filter for signal integrity applications. The 0805 package size constrains board layout options. Due to the discontinued status, alternative components with similar electrical characteristics and available supply chains should be evaluated for long-term production viability.

Part Context

The NFA21SL207X1A45L belongs to the Murata EMIFIL NFA21 series of combined array EMI filters. These components are engineered to suppress electromagnetic interference in multi-line configurations. The product utilizes LC technology to provide effective noise reduction while maintaining signal fidelity in space-constrained environments typical of modern portable electronics.
