NFL21SP106X1C3D

Overview

The NFL21SP106X1C3D is a multilayer EMI filter circuit from the Murata EMIFIL NFL21SP series, housed in an 0805 (2012 metric) surface-mount package. It features a Pi filter topology with a cutoff frequency of 20 MHz. Key electrical parameters include a capacitance of 670 pF, an inductance of 700 nH, and a DC voltage rating of 16 V. The component supports a maximum current of 100 mA and operates within a temperature range of -55°C to +125°C.

Feature Summary

• Integrates LC components into a compact monolithic structure for efficient space utilization
• Provides third-order filtering performance to suppress electromagnetic interference
• Engineered for high-temperature stability across a wide operational range

Applications

• High-speed data line protection in portable electronic devices
• EMI suppression in automotive infotainment systems
• Signal integrity enhancement in industrial control interfaces

Procurement Notes

Verify component authenticity through authorized distribution channels due to potential availability constraints. Confirm RoHS compliance status and specific lifecycle stage prior to integration. Ensure storage conditions align with manufacturer guidelines to maintain solderability and electrical performance over time.

Selection Notes

Select this component when a low-profile 0805 footprint is required for high-frequency noise attenuation. The 16V rating suits low-voltage digital circuits. Evaluate thermal requirements against the +125°C limit. Compare insertion loss characteristics against alternative filter topologies to ensure adequate signal preservation.

Part Context

This part belongs to the NFL21SP series of multilayer ceramic EMI filters manufactured by Murata Electronics. These components utilize proprietary thin-film technology to combine inductors and capacitors on a single substrate, offering superior performance compared to discrete component assemblies in constrained PCB areas.
