NFA21SL287V1A48L

Overview

The Murata NFA21SL287V1A48L is a second-order low-pass LC EMI filter array designed for surface mount applications. It features four channels within an 0805 (2012 metric) package, measuring 2.00 mm in length, 1.25 mm in width, and 0.60 mm in height. The component operates with a maximum DC voltage of 10 V and supports a continuous current rating of 100 mA. It exhibits a cutoff frequency of 280 MHz and provides 25 dB attenuation at 800 MHz. The device functions reliably across a temperature range of -55°C to +125°C.

Feature Summary

• Integrates four independent filtering channels into a compact single-component solution
• Provides effective suppression of electromagnetic interference on high-speed data lines
• Utilizes LC network topology for steep roll-off characteristics

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 codes against official Murata documentation to ensure correct capacitance and tolerance values. Confirm lifecycle status as distributors may list this part as Not Recommended for New Designs (NRND). Check RoHS compliance details directly from the manufacturer datasheet before finalizing procurement specifications.

Selection Notes

Select this component when space constraints require a multi-channel filter in an 0805 footprint. Ensure the circuit current does not exceed 100 mA and voltage remains below 10 V DC. Consider the 280 MHz cutoff frequency relative to the target signal bandwidth to avoid unwanted signal attenuation while maintaining necessary noise rejection capabilities.

Part Context

This part belongs to the EMIFIL NFA21SL series, which offers various capacitance options within the same physical package dimensions. The series is engineered specifically for protecting sensitive digital interfaces in consumer electronics where board real estate is limited and multiple signal lines require simultaneous filtering.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Verify compatibility with alternative components by matching package size, channel count, and electrical ratings against the original design requirements.
