Gowanda’s SM3-121K is a high-quality molded unshielded temperature stable inductor, designed for reliable performance in various applications. Weighing just 0.05 grams, it features compact dimensions of 2.98 × 2.29 × 2.18 mm, making it ideal for space-constrained environments. Part of the SM3 series, this surface-mount technology (SMT) component is classified under the COTS+ application grade, ensuring enhanced reliability. It offers 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 effectively up to a self-resonant frequency (SRF) of 90 MHz, tested at 4 MHz, with a tolerance of ±10%. Constructed with a powdered iron core, it is not shielded and can withstand operating temperatures ranging from -55°C to +125°C. The SM3-121K features Pb termination with a Sn63Pb37 finish, is moisture sensitivity level (MSL) 1 rated, and is packaged in tape and reel (T&R) format. Additionally, it is fungal inert, ensuring durability in various environments.
