The NFL21SP506X1C3D is part of Murata’s EMIFIL® series, designed to meet the growing need for robust EMI suppression in high-speed, space-constrained systems. Packaged in a compact 0805 footprint, this integrated π-type EMI filter combines two inductors and a central capacitor into a single component—ensuring consistent impedance matching, simplified PCB layout, and reliable high-frequency noise attenuation.

With a typical insertion loss of 30 dB at 500 MHz and effective suppression across 100 MHz to 1 GHz, the filter helps systems comply with strict EMC standards while maintaining signal integrity. Its 2 A current rating and low DCR (≤ 0.05 Ω) make it suitable for both signal lines and low-voltage power rails in compact designs.

Key Benefits:

• Integrated π-Type Topology: Eliminates mismatches from discrete layouts, ensuring consistent high-frequency performance.

• Strong EMI Suppression: 30 dB typical insertion loss at 500 MHz, ideal for high-speed data interfaces.

• Compact, High-Current Design: Fits in an 0805 package while supporting up to 2 A currents.

• Versatile Applications: Effective EMI filtering for USB, HDMI, MIPI, wireless modules, sensors, and power rails.

Engineered for mobile devices, communication modules, medical wearables, and industrial control systems, the NFL21SP506X1C3D offers a balance of size efficiency, EMI suppression, and electrical robustness. By integrating Murata’s advanced EMI filtering technology, it enables engineers to build more reliable, EMC-compliant designs without increasing board space.
