Gowanda’s SM3-471H is a molded unshielded temperature stable inductor, designed for high reliability in electronic applications. Weighing just 0.05 grams, it features compact dimensions of 2.98 × 2.29 × 2.18 mm and is part of the SM3 series. This surface-mount technology (SMT) component is classified under the COTS+ application grade, offering an inductance of 4.7 µH with a direct current resistance (DCR) of 1.9 Ω and a current rating of 0.33 A DC. It operates effectively within a frequency range, with a self-resonant frequency (SRF) of 45 MHz and a test frequency of 4 MHz. The inductor maintains a tolerance of ±3% and utilizes a powdered iron core. It is designed with lead (Pb) termination and a Sn63Pb37 termination finish, suitable for operating temperatures ranging from -55°C to +125°C. 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 performance in demanding environments.
