Gowanda’s 18M152K is a high-quality molded unshielded RF coil designed for reliable performance in various applications. With a weight of 0.95 g 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 15 µH and a minimum Q factor of 55 at a test frequency of 2.5 MHz. The coil has a direct current resistance (DCR) of 1.2 Ω and a self-resonant frequency (SRF) of 30 MHz, with a current rating of 0.31 A DC. It operates within a temperature range of -55°C to +125°C and has a dielectric withstanding voltage (DWV) of 200. The component is lead-terminated with a Sn63Pb37 finish, utilizing a powdered iron core, and is packaged in tape and reel (T&R) format. It is also fungal inert, ensuring durability and reliability in demanding environments.
