Gowanda’s CMF63-4703SM is a high-quality common mode transformer choke designed for demanding applications. Weighing just 0.85 grams, it features compact dimensions of 8.9 × 8.9 × 5.08 mm and is part of the CMF63SM series. This surface-mount technology (SMT) component is suitable for COTS+ application grades, offering an inductance of 470 µH and a direct current resistance (DCR) of 0.06 Ω. It supports a current rating of 1.5 A DC and has a leakage inductance of 1.6 µH. With a dielectric withstanding voltage (DWV) of 1250, it maintains a tolerance of ±25%. The choke is shielded, has a termination type of Pb with a Sn63Pb37 finish, and operates effectively in temperatures ranging from -55°C to +125°C. It is rated at moisture sensitivity level (MSL) 1 and is packaged in tape and reel (T&R) format, although it is not fungal inert.
