Gowanda’s GA30-472K is a high current power choke designed for demanding applications, featuring a compact size with dimensions of 22.86 × 11.43 × 11.43 mm and a weight of 2 grams. This component is part of the GA30 series and is mounted using through-hole technology (THT). It is suitable for COTS+ grade applications, offering an inductance of 47 µH with a direct current resistance (DCR) of 0.034 Ω. The GA30-472K supports a current rating of 3.658 A DC and a saturation current of 1.5 A DC, with a self-resonant frequency (SRF) of 3.2 MHz. It has a tolerance of ±10% and utilizes a lead (Pb) termination type with a Sn63Pb37 finish. The core is made of ferrite, and the component is not shielded. It operates effectively within a temperature range of -55°C to +125°C and has a moisture sensitivity level (MSL) of 1. The GA30-472K is packaged in tape and reel (T&R) format and is not fungal inert.
