Gowanda’s CMF61-6803SM is a surface-mount technology (SMT) common mode transformer choke designed for high reliability in electronic applications. Weighing just 0.5 grams and measuring 6.35 x 6.35 x 5.08 mm, this component is part of the CMF61SM series and is suitable for commercial off-the-shelf plus (COTS+) applications. It features an inductance of 680 µH, a direct current resistance (DCR) of 0.17 Ω, and a current rating of 0.5 A DC. The choke is shielded and operates within a temperature range of -55°C to +125°C, ensuring performance in diverse environments. With a dielectric withstanding voltage (DWV) of 1250 and a leakage inductance of 2 µH, it offers robust electrical characteristics. The component has a moisture sensitivity level (MSL) of 1 and is packaged in tape and reel (T&R) format. Its termination type is lead-based (Pb) with a finish of Sn63Pb37, although it is not fungal inert.
