Gowanda’s GA5-472K 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 suitable for COTS+ application grades, offering an inductance of 47 µH with a direct current resistance (DCR) of 0.35 Ω. The GA5-472K supports a current rating of 0.76 A DC and a saturation current of 430 A DC, with a self-resonant frequency (SRF) of 6 MHz and a tolerance of ±10%. The termination type is lead-based (Pb) with a Sn63Pb37 finish, and it features a ferrite core. Although it is not shielded, it operates reliably within a temperature range of -55°C to +125°C and has a moisture sensitivity level (MSL) of 1. The product is packaged in tape and reel (T&R) format and is not fungal inert.
