NFA21SL307X1A48L

Overview

The Murata NFA21SL307X1A48L is a surface-mount LC combined array EMI filter designed for high-frequency noise suppression. It features four channels within an 0805 (2012 Metric) package, measuring 2 mm in length and 1.25 mm in depth with a height of 0.85 mm. The component operates at a maximum DC voltage of 10V and supports a continuous current rating of 100 mA. It provides a cutoff frequency of 300 MHz and includes integrated capacitance values of 22 pF per channel. The device functions reliably across a temperature range of -55°C to +125°C.

Procurement Notes

Verify the specific part number against official Murata documentation to confirm electrical ratings and physical dimensions. Ensure compatibility with existing PCB footprints and thermal requirements. Confirm availability through authorized distributors as supply status may vary. Check for RoHS compliance and other relevant certifications required for your specific application environment before finalizing procurement decisions.

Selection Notes

Select this component when space constraints require a multi-channel filter in an 0805 footprint. Consider the 100 mA current rating and 10V voltage limit to ensure operational safety. Evaluate the 300 MHz cutoff frequency against target noise spectra. Verify that the integrated 22 pF capacitance aligns with signal line impedance and timing requirements without causing distortion.

Part Context

This component belongs to the NFA21SL series of EMIFIL arrays from Murata Electronics. These filters are engineered for compact electronic designs requiring efficient noise reduction in data lines. The series utilizes LC combined technology to achieve superior performance in small form factors, catering to the demands of modern mobile and portable devices.

Replacement Considerations

Consult official Murata documentation for verified substitute part numbers. Cross-reference specifications such as cutoff frequency, current rating, and package dimensions to ensure functional equivalence. Do not assume interchangeability based solely on package size.
