NFL21SP706X1C3D

Overview

The NFL21SP706X1C3D is a third-order low-pass LC Pi filter manufactured by Murata Electronics. It features an inductance of 185 nH and capacitance of 76 pF, with a cutoff frequency of 70 MHz. Rated for 16 V and 150 mA, this component utilizes a surface-mount 0805 (2012 metric) package with three PCB pads. The device operates within a temperature range of -55°C to +125°C and is classified as obsolete.

Feature Summary

• Integrates LC Pi topology for effective EMI suppression
• Provides third-order low-pass filtering characteristics
• Designed for high-frequency signal line protection

Applications

• General-purpose EMI suppression
• Signal line noise filtering
• High-frequency circuit interference reduction

Procurement Notes

This component is officially listed as obsolete by the manufacturer. Verify current availability through authorized distributors or secondary markets. Confirm end-of-life status and potential supply constraints before finalizing design specifications. Ensure compatibility with existing inventory strategies due to discontinuation.

Selection Notes

Select this part only if the specific 185 nH inductance and 76 pF capacitance values match the target circuit requirements. Consider the 0805 footprint dimensions and 150 mA current rating during layout planning. Evaluate alternative active components if continuous production volume is required due to the obsolete status.

Part Context
