Gowanda’s SMT45A-502 is a high-efficiency dual wound toroidal inductor designed for demanding applications, featuring a compact size of 15.5 × 12.2 × 6.35 mm and weighing 2.1 grams. This inductor is part of the SMT45A series and is suitable for surface mount technology (SMT) with a commercial off-the-shelf plus (COTS+) application grade. It offers an inductance of 50 µH with a direct current resistance (DCR) of 0.089 and 0.358 ohms, and a current rating of 1.03 and 2.05 A DC. The saturation current (I SAT) is 0.94 and 1.88 A DC, with a tolerance of ±25%. The component features a lead (Pb) termination type with a Sn63Pb37 finish and is constructed with a ferrite core. It operates efficiently within a temperature range of -55°C to +125°C, has a moisture sensitivity level (MSL) of 1, and is available in tape and reel (T&R) packaging.
