Gowanda’s CMF4-2503HC is a high-quality, epoxy-potted common mode choke designed for horizontal PC mounting. Weighing 23.5 grams and measuring 27.9 mm on each side, this component is part of the CMF4HC series and features through-hole technology (THT) for mounting. It is suitable for COTS+ application grades, offering an inductance of 250 µH with a direct current resistance (DCR) of 0.006 Ω and a current rating of 10 A DC. The choke has an interwinding capacitance of 12 pF and a leakage inductance of 3.5 µH, with a dielectric withstanding voltage (DWV) of 1250. It has a tolerance of ±30% and uses lead-based (Pb) terminations with a Sn63Pb37 finish. The component is not shielded and operates within a temperature range of -55°C to +125°C, with a moisture sensitivity level (MSL) of 1. It is packaged in bulk and is not fungal inert.
