NFA21SL307X1A45L

Overview

The NFA21SL307X1A45L is a surface-mount LC EMI filter manufactured by Murata Electronics. It features a second-order low-pass configuration with four independent channels housed in an 0805 (2012 Metric) array package measuring 2.00mm x 1.25mm x 0.60mm. The component has a rated voltage of 10V and supports a continuous current of 100 mA. It provides a cutoff frequency of 300MHz and achieves an attenuation of 25dB at 1GHz. The device operates within a temperature range of -55°C to +125°C.

Feature Summary

• Integrates four independent low-pass filtering channels within a compact surface-mount array footprint
• Utilizes LC technology to provide effective electromagnetic interference suppression for high-speed data lines
• Designed for robust operation across an extended industrial temperature range

Applications

• Data line protection in mobile devices
• High-speed interface circuits requiring EMI suppression
• Portable electronic equipment signal integrity management

Procurement Notes

Verify the specific suffix X1A45L against official Murata documentation to confirm the exact electrical characteristics, as ordering suffixes define critical parameters. Ensure compatibility with standard 0805 footprints during PCB layout. Confirm RoHS3 compliance status if required by regulatory standards. Cross-reference the manufacturer part number with authorized distributor catalogs to validate current availability and lifecycle status before finalizing procurement plans.

Selection Notes

Select this component when space-constrained designs require multi-channel EMI filtering in an 0805 package. The 100mA current rating suits moderate power applications, while the 10V rating defines the maximum operating voltage. Consider the 300MHz cutoff frequency relative to the target signal bandwidth to ensure adequate attenuation without excessive signal degradation. Verify thermal requirements align with the -55°C to +125°C operational range.
