Gowanda’s 3A272 is a wirewound high current power choke designed for demanding applications, featuring a compact size with dimensions of 22.23 × 22.23 × 20.62 mm and a weight of 53 g. This component is part of Series A and utilizes through-hole technology (THT) for mounting. It is classified under the COTS+ application grade, ensuring enhanced reliability and performance. The 3A272 offers an inductance of 27 µH with a direct current resistance (DCR) of 0.035 Ω and a current rating of 3 A DC. It operates effectively across a frequency range with a self-resonant frequency (SRF) of 7 MHz and maintains a tolerance of ±10%. The termination type is lead-based (Pb) with a Sn63Pb37 finish, suitable for environments with operating temperatures ranging from -55°C to +125°C. It is rated at moisture sensitivity level (MSL) 1 and is available in bulk packaging.
