Gowanda’s SM3-391J is a high-quality, reliable molded unshielded temperature stable inductor, designed for 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 ideal for COTS+ grade applications, offering an inductance of 3.9 µH with a DCR of 1.5 Ω and a current rating of 0.372 A DC. It operates effectively across a frequency range, with a self-resonant frequency (SRF) of 47 MHz and a test frequency of 4 MHz, maintaining a tolerance of ±5%. The inductor uses powdered iron as its core material and is not shielded. It is capable of operating in extreme temperatures ranging from -55°C to +125°C, with a moisture sensitivity level (MSL) of 1. The SM3-391J is packaged in tape and reel (T&R) format, features lead (Pb) termination with a Sn63Pb37 finish, and is fungal inert, ensuring durability and reliability in various environments.
