Gowanda’s 19M273G is a high-quality molded unshielded RF coil designed for reliable performance in various electronic applications. Weighing 1.3 grams and measuring 11.176 × 4.826 × 4.826 mm, this component is part of the 19M series and features through-hole technology (THT) mounting. It is suitable for commercial off-the-shelf (COTS) applications, offering an inductance of 270 µH with a minimum Q factor of 65 at a test frequency of 0.79 MHz. The coil has a DC resistance of 8.2 ohms and a self-resonant frequency of 5.6 MHz, with a current rating of 0.11 A DC. It is constructed with a powdered iron core and has a dielectric withstanding voltage (DWV) of 180. The component is lead-terminated with a Sn63Pb37 finish and operates within a temperature range of -55°C to +105°C. It is rated at moisture sensitivity level (MSL) 1, comes in tape and reel (T&R) packaging, and is fungal inert, ensuring durability and reliability in demanding environments.
