Gowanda’s SM3-121H is a molded unshielded temperature stable inductor designed for high reliability in electronic applications. Weighing just 0.05 grams and measuring 2.98 × 2.29 × 2.18 mm, this component is part of the SM3 series and is suitable for surface mount technology (SMT). It is classified as COTS+ application grade, offering an inductance of 1.2 µH with a direct current resistance (DCR) of 0.4 Ω and a current rating of 0.72 A DC. The inductor operates at a self-resonant frequency (SRF) of 90 MHz, tested at 4 MHz, with a tolerance of ±3%. It features a powdered iron core and is not shielded, with a termination type of Pb and a finish of Sn63Pb37. The SM3-121H is capable of functioning in temperatures ranging 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 durability and reliability in various environments.
