Gowanda’s CMF3-3003SM is a high-quality common mode transformer choke designed for demanding applications. With a weight of 9.73 grams and dimensions of 26.87 × 26.87 × 10.74 mm, this component is part of the CMF3SM series and features surface mount technology (SMT) for ease of installation. It is classified as COTS+ grade, ensuring reliability in commercial off-the-shelf applications. The choke offers an inductance of 300 µH, a direct current resistance (DCR) of 0.018 Ω, and a current rating of 6.3 A DC. It also boasts a leakage inductance of 3 µH and a dielectric withstanding voltage (DWV) of 1250. With a tolerance of ±30%, the component is shielded and operates effectively 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 fungal inert, making it suitable for various environmental conditions.
