NFA21SL337V1A48L

Overview

The NFA21SL337V1A48L is an LC EMI network filter array manufactured by Murata Electronics. It features a second-order low-pass circuit configuration with four independent channels housed in a compact 0805 (2012 Metric) surface-mount package. The component operates with a cutoff frequency of 330 MHz and supports a maximum current rating of 100 mA. Designed for high-performance signal integrity, it provides effective suppression of electromagnetic interference in dense electronic layouts while maintaining RoHS compliance.

Feature Summary

• Four-channel LC filter array architecture for multi-line signal protection
• Second-order low-pass filtering topology for enhanced attenuation
• Compact 0805 surface-mount footprint suitable for space-constrained designs

Applications

• High-speed data line EMI suppression
• USB interface signal filtering
• HDMI port noise reduction
• General-purpose I/O line protection

Procurement Notes

Verify the specific suffix V1A48L against the manufacturer's official documentation to ensure correct pinout and electrical characteristics. Confirm RoHS compliance status through certified datasheets or test reports prior to integration. Cross-reference the 0805 package dimensions with PCB layout requirements to guarantee mechanical fit and soldering reliability during assembly processes.

Selection Notes

Select this component when designing circuits requiring multi-channel EMI filtering within strict spatial limitations. The 100 mA current rating and 330 MHz cutoff frequency define its suitability for moderate-speed digital interfaces. Ensure the application environment does not exceed the thermal and voltage specifications outlined in the official Murata datasheet to maintain long-term operational stability.

Part Context

This part belongs to Murata's NFA series of EMI filter arrays, which are engineered for suppressing noise on high-speed data lines. These components integrate passive LC elements into a single package, replacing discrete filters to improve consistency and reduce board space. The series is widely utilized in consumer electronics and industrial equipment where signal integrity is critical.

Replacement Considerations

Consult Murata's official replacement guide for direct equivalents. Verify that any substitute maintains identical channel count, package size, and cutoff frequency specifications to prevent design modifications.
