The DR1050-220-R is a low-profile power inductor from the DR1050 series designed for use in DC-DC converters, buck/boost topologies, and noise filtering applications. It features a 22 µH rated inductance with an open-circuit inductance (OCL) of 23.5 µH (±30%), a shielded ferrite drum core measuring 10.3 mm × 10.5 mm × 5.0 mm, and operates at a maximum temperature of 125°C. The inductor delivers an RMS current rating of 3.12 A and a saturation current (Isat) of 3.00 A, with a typical DC resistance (DCR) of 38.7 mO and maximum DCR of 48.4 mO. This component is ideal for computer power supplies, notebook power systems, LCD panel applications, and portable power devices requiring compact, reliable inductance in the 22 µH range.
