Gowanda’s 18M272J is a high-quality molded unshielded RF coil designed for reliable performance in various applications. With a weight of 0.95 grams and compact dimensions of 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 27 µH and a minimum Q factor of 65 at a test frequency of 2.5 MHz. The coil has a direct current resistance (DCR) of 2.75 ohms and a self-resonant frequency (SRF) of 22 MHz, with a current rating of 0.205 A DC. It is built with a powdered iron core and operates within a temperature range of -55°C to +125°C. The component is rated MSL 1 for moisture sensitivity and is packaged in tape and reel (T&R) format. Its termination type is lead-based (Pb) with a Sn63Pb37 finish, ensuring durability and reliability. Additionally, the 18M272J is fungal inert, making it suitable for various environmental conditions.
