Gowanda’s SM3-221H is a molded unshielded temperature stable inductor, designed for high reliability in demanding applications. Weighing just 0.05 grams, it features compact dimensions of 2.98 × 2.29 × 2.18 mm and is part of the SM3 series. This surface-mount technology (SMT) component is graded COTS+ for commercial off-the-shelf applications, offering an inductance of 2.2 µH with a direct current resistance (DCR) of 0.8 Ω and a current rating of 0.509 A DC. It operates effectively across a frequency range, with a self-resonant frequency (SRF) of 60 MHz and a test frequency of 4 MHz. The inductor is built with a powdered iron core and features a termination type of Pb with a Sn63Pb37 finish. It is designed to withstand operating temperatures from -55°C to +125°C, has a moisture sensitivity level (MSL) of 1, and is packaged in tape and reel (T&R) format. Additionally, it is fungal inert, ensuring reliability in various environments.
