Gowanda’s 040AT7502SM is a high-quality wirewound toroidal inductor designed for demanding applications. With a weight of 3.5 grams and compact dimensions of 14.35 × 14.22 × 9.14 mm, this inductor is part of the ATSM series and features surface mount technology (SMT) for easy integration. It is suitable for COTS+ application grades, offering an inductance of 75 µH, a DCR of 0.14 Ω, and a self-resonant frequency of 9 MHz. The inductor supports a current rating of 1.69 A DC, with incremental current limits of 1300 mA DC for a 10% change and 2000 mA DC for a 20% change. It has a tolerance of ±10% and uses Pb termination with a Sn63Pb37 finish. The component operates reliably within a temperature range of -55°C to +130°C, has a moisture sensitivity level of 1, and is available in tape and reel packaging.
