Gowanda’s SM3-181H 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 graded as COTS+ for commercial off-the-shelf applications. It offers an inductance of 1.8 µH with a direct current resistance (DCR) of 0.7 Ω and a current rating of 0.544 A DC. The inductor operates at a self-resonant frequency (SRF) of 70 MHz, tested at 4 MHz, with a tolerance of ±3%. It uses a powdered iron core and has a termination type of Pb with a Sn63Pb37 finish. The SM3-181H is designed to function in a wide temperature range from -55°C to +125°C, has a moisture sensitivity level (MSL) of 1, and is packaged in tape and reel (T&R) format. Additionally, it is fungal inert, ensuring durability in various environments.
