NFA21SL207X1A48L

Overview

The Murata NFA21SL207X1A48L is a surface-mount LC EMI filter array in an 0805 (2.0x1.25mm) package with a height of 0.85 mm. It features four channels and operates within a frequency range of 800 MHz to 1 GHz. The component provides 25 dB attenuation and supports a maximum current of 100 mA at 10 V DC. It functions as a second-order low-pass filter with SMD/SMT termination, designed for steep insertion loss characteristics.

Feature Summary

• Provides steep insertion loss characteristics for effective noise suppression
• Designed for high-frequency applications above 800 MHz
• Compact surface-mount footprint suitable for space-constrained designs

Applications

• Noise suppression in high-frequency electronic circuits
• EMI/RFI filtering in mobile communication devices
• Signal integrity protection in data transmission lines

Procurement Notes

Verify the specific part number suffix against official Murata documentation to confirm exact electrical parameters and packaging details. Ensure compatibility with your PCB layout regarding the 0805 footprint dimensions. Check for any recent lifecycle status updates or recommended alternative components from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when designing circuits requiring significant attenuation in the 800 MHz to 1 GHz range. The four-channel configuration allows for simultaneous filtering of multiple signal lines within a minimal board area. Consider the 100 mA current rating to ensure it meets the operational requirements of the target application without saturation.

Part Context
