Gowanda’s 28M103K is a high-quality molded unshielded RF coil designed for reliable performance in various applications. With a weight of 2.65 grams and dimensions of 22.86 × 7.137 × 7.137 mm, this component is part of the 28M series and features through-hole technology (THT) mounting. It is suitable for commercial off-the-shelf (COTS) applications, offering an inductance of 100 µH and a minimum Q factor of 75 at a test frequency of 2.5 MHz. The coil has a direct current resistance (DCR) of 2.5 ohms and a self-resonant frequency (SRF) of 12 MHz, with a current rating of 0.245 A DC. It can withstand a dielectric withstanding voltage (DWV) of 1000, 200 and operates within a temperature range of -55°C to +125°C. The component is terminated with Pb and finished with Sn63Pb37, utilizing a powdered iron core. It is packaged in tape and reel (T&R), has a moisture sensitivity level (MSL) of 1, and is fungal inert, ensuring durability and reliability in demanding environments.
