SM3-471M

Gowanda’s SM3-471M is a high-quality, reliable molded unshielded temperature stable inductor designed for demanding 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+ application grade, ensuring enhanced performance and reliability. The SM3-471M offers an inductance of 4.7 µH, 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 is built with a powdered iron core and has a tolerance of ±20%. It is designed to withstand operating temperatures from -55°C to +125°C and is rated with a moisture sensitivity level (MSL) of 1. The termination type is Pb with a Sn63Pb37 finish, and it is packaged in tape and reel (T&R) format. Additionally, the SM3-471M is fungal inert, making it suitable for various environments.
