KEMET Ferrite Power Inductor, 220µH, 1.8A, 11g

The KEMET Ferrite Power Inductor from the SBC Series is an essential component for stable and efficient power management in modern electronic circuits. Featuring a robust drum core construction with a nickel-zinc (NiZn) ferrite core, this unshielded inductor is designed to deliver reliable performance in a compact form factor. Its high inductance value of 220µH makes it particularly effective in smoothing current and filtering noise in DC/DC converter applications.

This inductor is engineered to handle demanding conditions with an RMS current (Irms) rating of 1.8A and a saturation current (Isat) of 2.4A. A low maximum DC resistance of 0.17 ohm helps to minimise power loss and heat generation, contributing to overall system efficiency. The component operates reliably within a temperature range of up to +105°C, ensuring stability in various environmental conditions.
