## Description

The 2200LL-470-H-RC from Bourns is a toroidal inductor from the 2200LL series, featuring a 47 µH nominal inductance with ±15% tolerance, rated for 10.3 A RMS current with a maximum DC resistance of 0.012 Ω. This through-hole toroidal inductor utilizes a low core loss magnetic material in a toroidal winding configuration, which inherently minimizes magnetic radiation and reduces electromagnetic interference compared to bobbin-wound alternatives. The -H suffix designates horizontal mounting orientation, with vertical mounting (-V) available as an alternative configuration. The component operates across an extended temperature range of -55 °C to +125 °C, with the rated DC current specified at a 30 °C temperature rise above ambient.

Designed for high-current power conversion applications, this inductor serves as an output choke in switch-mode power supplies and DC/DC converters, including buck, boost, and flyback topologies. The low DCR minimizes conduction losses and improves overall converter efficiency, while the toroidal construction provides excellent self-shielding properties that reduce near-field coupling to adjacent components. The 2200LL series is RoHS compliant (indicated by -RC suffix) and suited for industrial power systems, telecommunications equipment, and distributed power architectures where compact magnetic components with high current handling and minimal EMI signature are required.
