Gowanda’s SMT45A-332 is a high-efficiency dual wound toroidal inductor designed for demanding applications. Weighing 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 as COTS+ grade, ensuring reliability in commercial off-the-shelf applications. The inductor offers an inductance of 33 µH with a direct current resistance (DCR) of 0.061 and 0.243 ohms, supporting current ratings of 1.25 and 2.49 A DC. It has a saturation current (I SAT) of 1.13 and 2.25 A DC, with a tolerance of ±25%. The component uses a ferrite core and has a termination type of Pb with a Sn63Pb37 finish. It operates efficiently in temperatures ranging from -55°C to +125°C and is rated at moisture sensitivity level (MSL) 1, making it suitable for various environments. The inductor is packaged in tape and reel (T&R) format for streamlined handling and deployment.
