Gowanda’s SMT45A-820 is a high efficiency dual wound toroidal inductor designed for demanding applications. Weighing just 2.1 grams and measuring 15.5 × 12.2 × 6.35 mm, this component is part of the SMT45A series and features surface mount technology (SMT) for easy integration. It is classified under COTS+ application grade, offering an inductance of 0.82 µH with a direct current resistance (DCR) of 0.0034 and 0.0136 ohms. The inductor supports a current rating of 10.6 and 5.28 A DC, with a saturation current (I SAT) of 15 and 7.5 A DC. It has a tolerance of ±25% and uses a lead-based termination type with a Sn63Pb37 finish. Constructed with a ferrite core, the inductor is not shielded and operates efficiently within a temperature range of -55°C to +125°C. It is rated at moisture sensitivity level (MSL) 1 and is available in tape and reel (T&R) packaging for streamlined handling and deployment.
