Gowanda’s 18M561GLF is a high-quality, reliable molded unshielded RF coil designed for COTS applications. Weighing 0.95 grams and measuring 11.125 × 4.775 × 4.775 mm, this component is part of the 18M series and features through-hole technology (THT) mounting. It offers an inductance of 5.6 µH with a minimum Q factor of 30, tested at a frequency of 7.9 MHz. The coil has a DC resistance of 0.28 ohms and a self-resonant frequency of 50 MHz, with a current rating of 0.645 A DC. It can withstand a dielectric withstanding voltage of 200 volts and has a tolerance of ±2%. The termination is RoHS compliant with a Sn/Cu finish, and the core is made of powdered iron. Operating within a temperature range of -55°C to +125°C, it is packaged in tape and reel (T&R) format and is fungal inert, with a moisture sensitivity level of 1.
