Gowanda’s 18M122J is a high-quality molded unshielded RF coil designed for reliable performance in various electronic applications. With a weight of 0.95 grams and dimensions of 11.125 × 4.775 × 4.775 mm, this component is part of the 18M series and features through-hole technology (THT) mounting. It is suitable for commercial off-the-shelf (COTS) applications, offering an inductance of 12 µH and a minimum Q factor of 50 at a test frequency of 2.5 MHz. The coil has a DC resistance of 1.05 ohms and a self-resonant frequency of 36 MHz, with a current rating of 0.37 A DC. It can withstand a dielectric withstanding voltage (DWV) of 200 volts and maintains a tolerance of ±5%. The termination type is lead-based with a Sn63Pb37 finish, and the core is made of powdered iron. Operating effectively in temperatures ranging from -55°C to +125°C, the component is rated at moisture sensitivity level 1 and is packaged in tape and reel (T&R) format. Additionally, it is fungal inert, ensuring durability and reliability in various environments.
