Gowanda’s SMRF1210-390K is a molded unshielded inductor designed for high reliability in electronic applications. Weighing just 0.05 grams and measuring 3 × 2.16 × 2.06 mm, this component is part of the SMRF1210 series and is suitable for surface mount technology (SMT). It is classified under COTS+ application grade, offering an inductance of 0.39 µH with a direct current resistance (DCR) of 0.45 Ω and a current rating of 0.679 A DC. The inductor operates at a self-resonant frequency (SRF) of 250 MHz, with a test frequency of 25 MHz and a minimum quality factor (Q) of 30. It features a tolerance of ±10% and uses a powdered iron core. The termination type is lead-based (Pb) with a Sn63Pb37 finish, and it is not shielded. The operating temperature range is from -55°C to +125°C, with a moisture sensitivity level (MSL) of 1. Packaged in tape and reel (T&R), the inductor is also fungal inert, ensuring durability and reliability in various environments.
