The SMT45A-202 is a high-efficiency dual wound toroidal inductor from Gowanda, designed for superior performance in electronic applications. Weighing 2.1 grams and measuring 15.5 × 12.2 × 6.35 mm, this inductor is part of the SMT45A series and features surface mount technology (SMT) for easy integration. It is classified as COTS+ application grade, offering an inductance of 20 µH with a direct current resistance (DCR) of 0.029 and 0.115 ohms. The current rating is 1.81 and 3.62 A DC, with a saturation current (I SAT) of 1.5 and 3 A DC. The inductor has a tolerance of ±25% and uses a lead (Pb) termination type with a Sn63Pb37 finish. Constructed with a ferrite core, it is not shielded and operates effectively within a temperature range of -55°C to +125°C. It has a moisture sensitivity level (MSL) of 1 and is available in tape and reel (T&R) packaging.
