Gowanda’s SM3-390F is a molded unshielded temperature stable inductor designed for high reliability in electronic applications. Weighing just 0.05 grams, this compact component measures 2.98 × 2.29 × 2.18 mm and is part of the SM3 series. It features a surface-mount technology (SMT) mounting type and is graded as COTS+ for commercial off-the-shelf applications. With an inductance of 0.39 µH, a direct current resistance (DCR) of 0.17 Ω, and a current rating of 1.104 A DC, it operates efficiently across a frequency range with a self-resonant frequency (SRF) of 320 MHz and a test frequency of 10 MHz. The inductor offers a tight tolerance of ±1% and utilizes a powdered iron core. It is lead-terminated with a Sn63Pb37 finish and is capable of functioning in temperatures ranging from -55°C to +125°C. Rated with a moisture sensitivity level (MSL) of 1, it is packaged in tape and reel (T&R) format and is fungal inert, ensuring durability and reliability in various environments.
