Gowanda’s SM3-681K is a high-quality, reliable molded unshielded temperature stable inductor designed for demanding applications. Weighing just 0.05 grams and measuring 2.98 × 2.29 × 2.18 mm, this inductor is part of the SM3 series and is suitable for surface mount technology (SMT). It features an inductance of 6.8 µH, a direct current resistance (DCR) of 2.2 Ω, and a current rating of 0.307 A DC. With a self-resonant frequency (SRF) of 35 MHz and a test frequency of 4 MHz, it offers a tolerance of ±10%. The inductor uses a powdered iron core and has a termination type of Pb with a Sn63Pb37 finish. It operates effectively within a temperature range of -55°C to +125°C and is classified as MSL 1, ensuring high reliability. Packaged in tape and reel (T&R) format, it is also fungal inert, making it ideal for COTS+ grade applications.
