Gowanda’s 19M743GLF is a high-quality molded unshielded RF coil designed for reliable performance in various electronic applications. With a weight of 1.3 grams and compact dimensions of 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 750 µH and a minimum Q factor of 60 at a test frequency of 0.79 MHz. The coil has a direct current resistance (DCR) of 14.4 ohms and a self-resonant frequency (SRF) of 3.3 MHz, with a current rating of 0.083 A DC. It is built with a powdered iron core and is not shielded, operating efficiently within a temperature range of -55°C to +105°C. The component is rated with a dielectric withstanding voltage (DWV) of 180 and a tolerance of ±2%. It features leaded termination with a Sn63Pb37 finish and is packaged in tape and reel (T&R) format, ensuring ease of handling and assembly. Additionally, it is fungal inert, making it suitable for various environmental conditions.
