Gowanda’s GA40-273K is a high current power choke designed for demanding applications, featuring a weight of 7 grams and compact dimensions of 22.86 × 11.43 × 11.43 mm. Part of the GA40 series, this component is tailored for through-hole technology (THT) mounting and is classified under the COTS+ application grade, ensuring high reliability. It offers an inductance of 270 µH with a direct current resistance (DCR) of 0.208 Ω, supporting a current rating of 1.465 A DC and a saturation current of 1.63 A DC. The choke maintains a tolerance of ±10% and utilizes a lead-based termination type with a Sn63Pb37 finish. Constructed with a ferrite core, it operates effectively within a temperature range of -55°C to +125°C and is rated at moisture sensitivity level (MSL) 1. The component is packaged in tape and reel (T&R) format, though it is not fungal inert.
