Gowanda’s SM3-331G is a molded unshielded temperature stable inductor designed for high reliability in electronic applications. With a compact size of 2.98 × 2.29 × 2.18 mm and a weight of just 0.05 g, it is ideal for space-constrained environments. This inductor belongs to the SM3 series and features surface mount technology (SMT) for easy integration. It is classified as COTS+ grade, ensuring suitability for commercial off-the-shelf applications. The SM3-331G offers an inductance of 3.3 µH, a direct current resistance (DCR) of 1 Ω, and a current rating of 0.455 A DC. It operates effectively across a frequency range with a self-resonant frequency (SRF) of 50 MHz and a test frequency of 4 MHz. The component is built with a powdered iron core and has a tolerance of ±2%. It is equipped with Pb termination type and Sn63Pb37 termination finish, ensuring reliable connections. The inductor is designed to operate in temperatures ranging from -55°C to +125°C and has a moisture sensitivity level (MSL) of 1. Packaged in tape and reel (T&R) format, it is also fungal inert, making it suitable for various demanding environments.
