Gowanda’s 19M683JLF 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 680 µH and a minimum Q factor of 60 at a test frequency of 0.79 MHz. The coil has a DC resistance of 13.7 ohms and a self-resonant frequency of 3.4 MHz, with a current rating of 0.085 A DC. It is designed to withstand a dielectric withstanding voltage (DWV) of 180 volts and maintains a tolerance of ±5%. The termination type is RoHS compliant with a Sn/Cu finish, and the core is made of powdered iron. Operating efficiently in temperatures ranging from -55°C to +105°C, the coil is rated at moisture sensitivity level (MSL) 1 and is packaged in tape and reel (T&R) format, ensuring fungal inertness.
