Gowanda’s CMF4-2503H is a high-quality, horizontally mounted common mode choke designed for demanding applications. Weighing 14 grams and measuring 26.42 × 26.42 × 11.18 mm, this component is part of the CMF4H series and features through-hole technology (THT) for robust mounting. It is classified as COTS+ grade, ensuring reliability in commercial off-the-shelf applications. With an inductance of 250 µH, a direct current resistance (DCR) of 0.0038 Ω, and a current rating of 12 A DC, it is engineered for efficient performance. The choke has an interwinding capacitance of 8 pF and a leakage inductance of 3.2 µH, with a dielectric withstanding voltage (DWV) of 1250. It offers a tolerance of ±30% and uses lead-based (Pb) terminations with a Sn63Pb37 finish. Operating effectively in temperatures ranging from -55°C to +125°C, it is rated at moisture sensitivity level (MSL) 1 and is packaged in bulk. Notably, it is not shielded and is not fungal inert.
