Gowanda’s SM3-331M is a high-quality, reliable molded unshielded temperature stable inductor designed for demanding applications. With a compact weight of 0.05 g and dimensions of 2.98 × 2.29 × 2.18 mm, it is part of the SM3 series and features surface mount technology (SMT) for ease of integration. This inductor is suitable for COTS+ grade applications, offering an inductance of 3.3 µH, a DCR of 1 Ω, and a current rating of 0.455 A DC. It operates effectively within a frequency range, with a self-resonant frequency (SRF) of 50 MHz and a test frequency of 4 MHz. The SM3-331M is built with powdered iron core material, has a tolerance of ±20%, and is designed to function in temperatures ranging from -55°C to +125°C. It features Pb termination type with a Sn63Pb37 finish, is fungal inert, and comes in tape and reel (T&R) packaging, ensuring it meets the highest standards of reliability and performance.
