Gowanda’s 18M121MLF is a high-quality, reliable molded unshielded RF coil designed for a variety of applications, particularly in commercial off-the-shelf (COTS) environments. This component features a compact design with dimensions of 11.125 × 4.775 × 4.775 mm and a weight of 0.95 g, making it suitable for through-hole technology (THT) mounting. It offers an inductance of 1.2 µH with a minimum Q factor of 30, tested at a frequency of 7.9 MHz. The coil has a DC resistance of 0.4 Ω and a self-resonant frequency of 180 MHz, supporting a current rating of 0.785 A DC. With a dielectric withstanding voltage (DWV) of 200, it operates efficiently across a temperature range of -55°C to +125°C. The component is RoHS compliant, featuring 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 various conditions.
