Gowanda’s SMRF5025S-391K is a molded shielded inductor designed for high reliability and performance in electronic applications. Weighing 0.95 grams and measuring 12.45 × 5.84 × 5.33 mm, this component is part of the SMRF5025S series and is suitable for surface mount technology (SMT). It features an inductance of 3.9 µH with a direct current resistance (DCR) of 0.4 Ω and a current rating of 0.97 A DC. The inductor operates efficiently with a self-resonant frequency (SRF) of 64 MHz and a minimum quality factor (Q MIN) of 40 at a test frequency of 7.9 MHz. It is constructed with a powdered iron core and is shielded to minimize electromagnetic interference. The component is designed for a wide operating temperature range from -55°C to +125°C and is packaged in tape and reel (T&R) format. It is compliant with COTS+ application grade standards, features a Pb termination type with a Sn63Pb37 finish, and is fungal inert, ensuring durability and reliability in various environments.
