Overview
The Murata NFA21SL287V1A45L is a surface-mount LC EMI filter array designed for noise suppression in mobile device data lines. It features four channels with a second-order low-pass configuration and a cutoff frequency of 280 MHz. The component operates within a temperature range of -55°C to 125°C and supports a rated voltage of 10 VDC with a current capacity of 100 mA. Housed in a compact 0805 (2.00mm x 1.25mm) package, it provides 25 dB attenuation at 800 MHz.
Feature Summary
- Four-channel low-pass LC filter architecture for multi-line signal integrity
- Steep insertion loss characteristics optimized for high-frequency noise suppression
- Compact 0805 footprint suitable for space-constrained mobile applications
Applications
- Noise suppression in mobile device data lines
- EMI filtering for high-speed digital interfaces
- Signal protection in portable electronic equipment
Procurement Notes
Verify the complete part number including suffixes to ensure correct packaging and specifications. Confirm RoHS3 compliance and moisture sensitivity level requirements during integration. Cross-reference official Murata documentation for any recent product change notices or lifecycle status updates before finalizing procurement plans.
Selection Notes
Select this component when four independent low-pass filters are required in a single package for data line protection. The 100 mA current rating and 10 VDC limit define the electrical boundaries. Ensure the 280 MHz cutoff frequency aligns with the target signal bandwidth while providing adequate attenuation above that threshold.
Part Context
This component belongs to the Murata EMIFIL NFA21 series, which specializes in small-footprint EMI suppression arrays. The NFA21 series is engineered for mobile devices, offering high performance in minimal board space compared to discrete filter solutions.
Replacement Considerations
Consult Murata's official substitution guide for verified alternatives. No public substitute part numbers are confirmed in the provided documentation.
