Gowanda’s 28M561G is a high-quality molded unshielded RF coil designed for reliable performance in various electronic applications. Weighing 2.65 grams and measuring 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 5.6 µH with a minimum Q factor of 60 at a test frequency of 7.9 MHz. The coil has a DC resistance of 0.745 ohms and a self-resonant frequency of 80 MHz, with a current rating of 0.745 A DC. It can withstand dielectric withstanding voltages (DWV) of 1000 and 200 volts. The component has a tolerance of ±2% and uses lead-based (Pb) terminations with a Sn63Pb37 finish. Constructed with a phenolic core, it operates effectively in temperatures ranging from -55°C to +105°C and is rated with a moisture sensitivity level (MSL) of 1. Packaged in tape and reel (T&R) format, the coil is also fungal inert, ensuring durability and reliability in diverse environments.
