Gowanda’s SM3-222K is a molded unshielded temperature stable inductor designed for high reliability in demanding applications. Weighing just 0.05 grams, it features compact dimensions of 2.98 × 2.29 × 2.18 mm, making it ideal for space-constrained environments. Part of the SM3 series, this surface-mount technology (SMT) component is graded COTS+ for commercial off-the-shelf applications. It offers an inductance of 22 µH with a direct current resistance (DCR) of 6.7 Ω and a current rating of 0.176 A DC. The inductor operates effectively across a frequency range, with a self-resonant frequency (SRF) of 15 MHz and a test frequency of 1 MHz. It maintains performance within a tolerance of ±10% and is constructed with a powdered iron core. The SM3-222K is lead-terminated with a Sn63Pb37 finish, ensuring reliable connections. It operates within a temperature range of -55°C to +125°C and is rated MSL 1 for moisture sensitivity. Packaged in tape and reel (T&R) format, it is also fungal inert, enhancing its suitability for various electronic applications.
