Gowanda’s GA10-121K is a high current power choke designed for demanding applications, featuring a compact size with dimensions of 16 × 6.6 × 6.6 mm and a weight of 2 grams. This component belongs to the GA10 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 1.2 µH with a direct current resistance (DCR) of 0.01 Ω, supporting a current rating of 5.272 A DC and a saturation current of 6.3 A DC. It operates effectively across a frequency range with a self-resonant frequency (SRF) of 148 MHz and maintains a tolerance of ±10%. The termination type is lead-based with a Sn63Pb37 finish, and the core material is ferrite. Although it is not shielded, it operates within a temperature range of -55°C to +125°C and has a moisture sensitivity level (MSL) of 1. The product is available in tape and reel (T&R) packaging but is not fungal inert.
