Gowanda’s CMF3-2003SM is a high-quality common mode transformer choke designed for demanding applications. This component, part of the CMF3SM series, features a compact size with dimensions of 26.87 × 26.87 × 10.74 mm and a weight of 9.73 g. It is surface mountable (SMT) and suitable for COTS+ grade applications. The choke offers an inductance of 200 µH with a direct current resistance (DCR) of 0.014 Ω and a current rating of 7.2 A DC. It also has a leakage inductance of 2 µH and a dielectric withstanding voltage (DWV) of 1250. The component is shielded, ensuring minimal electromagnetic interference, and operates efficiently across a wide temperature range from -55°C to +125°C. It features a Pb termination type with a Sn63Pb37 finish, is rated MSL 1 for moisture sensitivity, and is packaged in tape and reel (T&R) format. Additionally, it is fungal inert, making it suitable for various environmental conditions.
