Gowanda’s GA5-273K is a high current power choke designed for demanding applications, featuring a compact size with dimensions of 10.16 × 4.064 × 4.064 mm and a weight of 0.6 g. This component is part of the GA5 series and is mounted using through-hole technology (THT). It is classified under the COTS+ application grade, ensuring high reliability and performance. The choke offers an inductance of 270 µH with a direct current resistance (DCR) of 2.1 Ω and a current rating of 0.31 A DC. It can handle a saturation current of 180 A DC and operates at a self-resonant frequency (SRF) of 2.1 MHz. With a tolerance of ±10%, the GA5-273K features a lead-based termination type with a Sn63Pb37 finish and a ferrite core. It is designed to operate in a wide temperature range from -55°C to +125°C, with a moisture sensitivity level (MSL) of 1, and is packaged in tape and reel (T&R) format. However, it is not shielded and is not fungal inert.
