Gowanda’s SM3-392K is a molded unshielded temperature stable inductor, designed for high reliability in demanding applications. Weighing just 0.05 grams and measuring 2.98 × 2.29 × 2.18 mm, this component is part of the SM3 series and is suitable for surface mount technology (SMT). It is classified as COTS+ grade, offering an inductance of 39 µH with a direct current resistance (DCR) of 9.5 Ω and a current rating of 0.148 A DC. The inductor features a self-resonant frequency (SRF) of 12 MHz, tested at 1 MHz, with a tolerance of ±10%. It uses a powdered iron core and has a lead-based termination type with a Sn63Pb37 finish. Operating efficiently in temperatures ranging from -55°C to +125°C, it is rated at moisture sensitivity level (MSL) 1 and is packaged in tape and reel (T&R) format. Additionally, the SM3-392K is fungal inert, ensuring durability and reliability in various environments.
