Gowanda’s SMT45A-121 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+ application grade, offering an inductance of 1.2 µH with a direct current resistance (DCR) of 0.0045 and 0.0177 ohms. The inductor supports a current rating of 4.62 and 9.23 A DC, with a saturation current (I SAT) of 11.25 and 5.63 A DC, and a tolerance of ±25%. It utilizes a ferrite core and has a termination type of Pb with a Sn63Pb37 finish. Although not shielded, it operates efficiently within a temperature range of -55°C to +125°C and has a moisture sensitivity level (MSL) of 1, making it suitable for various environments. The SMT45A-121 is packaged in tape and reel (T&R) for convenient handling and deployment.
