Gowanda’s SMRF1512-393KS is an unshielded epoxy-coated chip inductor designed for high reliability in demanding applications. As part of the COTS M83446/10 series, this component features a compact size with dimensions of 3.94 × 3.175 × 3.56 mm and a weight of just 0.12 g. It is suitable for surface mount technology (SMT) and offers an inductance of 390 µH with a direct current resistance (DCR) of 32 Ω. The inductor supports a current rating of 0.039 A DC and a self-resonant frequency (SRF) of 2.9 MHz, tested at a frequency of 0.79 MHz with a minimum Q factor of 40. It has a tolerance of ±10% and features Pb, RoHS-compliant terminations with Sn63Pb37 and SnCu finishes. Built with a powdered iron core, it operates effectively in temperatures ranging from -55°C to +125°C and is rated at moisture sensitivity level (MSL) 1, making it ideal for various commercial off-the-shelf (COTS+) applications. The product is available in tape and reel (T&R) packaging for efficient handling and assembly.
