Gowanda’s 28M682G is a high-quality molded unshielded RF coil designed for reliable performance in various electronic applications. This component, part of the 28M series, features a compact design with dimensions of 22.86 × 7.137 × 7.137 mm and a weight of 2.65 g. It is tailored for through-hole technology (THT) mounting and is suitable for commercial off-the-shelf (COTS) applications. With an inductance of 68 µH and a minimum Q factor of 75, it operates efficiently at a test frequency of 2.5 MHz. The coil has a direct current resistance (DCR) of 1.85 Ω and a self-resonant frequency (SRF) of 13 MHz, supporting a current rating of 0.285 A DC. It is constructed with a powdered iron core and features a termination type of Pb with a Sn63Pb37 finish. The component is designed to withstand a dielectric withstanding voltage (DWV) of 1000, 200 and operates within a temperature range of -55°C to +125°C. It is packaged in tape and reel (T&R) format, has a moisture sensitivity level (MSL) of 1, and is fungal inert, ensuring durability and reliability in demanding environments.
