Gowanda’s SM3-391MLF is a high-quality, reliable electronic component designed for demanding applications. This molded unshielded temperature stable inductor is part of the SM3 series and is suitable for surface mount technology (SMT) with a compact size of 2.98 × 2.29 × 2.18 mm and a weight of just 0.05 g. It features an inductance of 3.9 µH, a direct current resistance (DCR) of 1.5 Ω, and a current rating of 0.372 A DC. The inductor operates efficiently across a wide temperature range from -55°C to +125°C and is characterized by a self-resonant frequency (SRF) of 47 MHz, tested at 4 MHz. With a tolerance of ±20%, RoHS-compliant termination, and a Sn100 finish, it is ideal for COTS+ application grades. The core is made of powdered iron, and while it is not shielded, it is fungal inert and comes in tape and reel (T&R) packaging, with a moisture sensitivity level (MSL) of 1.
