Gowanda’s GA5-474K 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 belongs to the GA5 series and is mounted using through-hole technology (THT). It is suitable for COTS+ grade applications, offering an inductance of 4700 µH with a tolerance of ±10%. The GA5-474K has a direct current resistance (DCR) of 37 Ω and can handle a current rating of 0.074 A DC, with a saturation current of 44 A DC. Its self-resonant frequency (SRF) is 0.45 MHz. The choke is constructed with a ferrite core and is not shielded. It operates efficiently across a temperature range of -55°C to +125°C and has a moisture sensitivity level (MSL) of 1. The termination type is Pb with a Sn63Pb37 finish, and it is packaged in tape and reel (T&R) format. The component is not fungal inert.
