Gowanda’s 18M220KLF is a high-quality molded unshielded RF coil designed for reliable performance in various electronic 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 is suitable for commercial off-the-shelf (COTS) applications, offering an inductance of 0.22 µH with a minimum Q factor of 50 at a test frequency of 25 MHz. The coil has a direct current resistance (DCR) of 0.035 ohms and a self-resonant frequency (SRF) of 415 MHz, with a current rating of 2.8 A DC. It is designed to withstand a dielectric withstanding voltage (DWV) of 200 volts and has a tolerance of ±10%. The termination type is RoHS compliant with a Sn/Cu finish, and the core is made of phenolic material. Operating efficiently in temperatures ranging from -55°C to +125°C, the component is rated at moisture sensitivity level (MSL) 1 and is packaged in tape and reel (T&R) format. Additionally, it is fungal inert, ensuring durability and reliability in demanding environments.
