SM3-220K

Gowanda’s SM3-220K is a molded unshielded temperature stable inductor, designed for high reliability in electronic applications. Weighing just 0.05 grams and measuring 2.98 × 2.29 × 2.18 mm, this component is part of the SM3 series and is suitable for surface mount technology (SMT). It is classified as COTS+ application grade, offering an inductance of 0.22 µH with a direct current resistance (DCR) of 0.12 Ω and a current rating of 1.314 A DC. The inductor features a self-resonant frequency (SRF) of 452 MHz and is tested at a frequency of 10 MHz, with a tolerance of ±10%. It utilizes a powdered iron core and has a termination type of Pb with a Sn63Pb37 finish. Operating efficiently within a temperature range of -55°C to +125°C, it is rated at moisture sensitivity level (MSL) 1 and is packaged in tape and reel (T&R) format. Additionally, the SM3-220K is fungal inert, ensuring durability in various environments.
