Gowanda’s SM3-391F is a molded unshielded temperature stable inductor designed for high reliability in electronic 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 suitable for COTS+ application grades, offering an inductance of 3.9 µH with a direct current resistance (DCR) of 1.5 Ω and a current rating of 0.372 A DC. It has a self-resonant frequency (SRF) of 47 MHz and is tested at a frequency of 4 MHz, with a tight tolerance of ±1%. The inductor uses a powdered iron core and features lead-based (Pb) terminations with a Sn63Pb37 finish. It operates effectively within a temperature range of -55°C to +125°C and has a moisture sensitivity level (MSL) of 1. Packaged in tape and reel (T&R) format, it is also fungal inert, ensuring durability and reliability in various environments.
