Gowanda’s SM3-391H is a high-quality, reliable electronic component designed for demanding applications. This molded unshielded temperature stable inductor is part of the SM3 series and features a compact size with dimensions of 2.98 × 2.29 × 2.18 mm and a weight of just 0.05 g. It is suitable for surface mount technology (SMT) and is classified under the COTS+ application grade. The inductor offers an inductance of 3.9 µH, a direct current resistance (DCR) of 1.5 Ω, and a current rating of 0.372 A DC. It operates effectively within a frequency range, with a self-resonant frequency (SRF) of 47 MHz and a test frequency of 4 MHz. The component is built with a powdered iron core and has a tolerance of ±3%. It features lead-based (Pb) terminations with a Sn63Pb37 finish, ensuring reliable connections. The SM3-391H is designed to withstand operating temperatures from -55°C to +125°C and has a moisture sensitivity level (MSL) of 1, making it suitable for various environmental conditions. Additionally, it is fungal inert and comes in tape and reel (T&R) packaging for easy handling and installation.
