Gowanda’s 18M182K 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) for easy mounting. It is suitable for commercial off-the-shelf (COTS) applications, offering an inductance of 18 µH with a minimum Q factor of 60 at a test frequency of 2.5 MHz. The coil has a direct current resistance (DCR) of 1.95 Ω and a self-resonant frequency (SRF) of 30 MHz, with a current rating of 0.255 A DC. It is constructed with a powdered iron core and has a dielectric withstanding voltage (DWV) of 200. The component is lead-terminated with a Sn63Pb37 finish, operates within a temperature range of -55°C to +125°C, and is rated at moisture sensitivity level (MSL) 1. Packaged in tape and reel (T&R) format, it is also fungal inert, ensuring durability and reliability in demanding environments.
