Gowanda’s 18M220MLF is a high-quality, reliable molded unshielded RF coil designed for various applications, particularly in the COTS (Commercial Off-The-Shelf) sector. 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) for mounting. It offers an inductance of 0.22 µH with a minimum Q factor of 50 at a test frequency of 25 MHz. The coil has a DC resistance of 0.035 ohms and a self-resonant frequency of 415 MHz, supporting a current rating of 2.8 A DC. It is designed to operate within a temperature range of -55°C to +125°C and has a dielectric withstanding voltage of 200. The component is RoHS compliant with Sn/Cu termination finish and is packaged in tape and reel (T&R) format. Its phenolic core and fungal inert properties ensure durability and reliability in demanding environments.
