SM3-221G

Gowanda’s SM3-221G 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, making it suitable for space-constrained environments. Part of the SM3 series, this surface-mount technology (SMT) component is classified under the COTS+ application grade, ensuring enhanced performance. It offers an inductance of 2.2 µH with a direct current resistance (DCR) of 0.8 Ω and a current rating of 0.509 A DC. The inductor operates effectively within a frequency range, with a self-resonant frequency (SRF) of 60 MHz and a test frequency of 4 MHz. It maintains precision with a tolerance of ±2% and features a lead-based termination type with a Sn63Pb37 finish. Constructed with a powdered iron core, it is designed to operate in temperatures ranging from -55°C to +125°C and is rated at moisture sensitivity level (MSL) 1. Packaged in tape and reel (T&R) format, the SM3-221G is also fungal inert, ensuring durability and reliability in various environments.
