Gowanda’s SM3-181K 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 and is part of the SM3 series. This surface-mount technology (SMT) component is classified as COTS+ grade, making it suitable 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 self-resonant frequency (SRF) is 70 MHz, tested at a frequency of 4 MHz, with a tolerance of ±10%. The inductor uses a powdered iron core and is not shielded, operating efficiently within a temperature range of -55°C to +125°C. It has a moisture sensitivity level (MSL) of 1 and is packaged in tape and reel (T&R) format. The termination type is lead-based (Pb) with a finish of Sn63Pb37, and it is also fungal inert, ensuring durability and reliability in various environments.
