Gowanda’s 19M273MLF is a high-quality molded unshielded RF coil designed for reliable performance in various electronic applications. With a weight of 1.3 grams and dimensions of 11.176 × 4.826 × 4.826 mm, this component is part of the 19M series and features through-hole technology (THT) for mounting. It is suitable for commercial off-the-shelf (COTS) applications, offering an inductance of 270 µH and a minimum Q factor of 65 at a test frequency of 0.79 MHz. The coil has a direct current resistance (DCR) of 8.2 ohms and a self-resonant frequency (SRF) of 5.6 MHz, with a current rating of 0.11 A DC. It can withstand a dielectric withstanding voltage (DWV) of 180 volts and has a tolerance of ±20%. The termination type is RoHS compliant with a Sn/Cu finish, and the core is made of powdered iron. The component operates effectively within a temperature range of -55°C to +105°C, has a moisture sensitivity level (MSL) of 1, and is packaged in tape and reel (T&R) format. Additionally, it is fungal inert, ensuring durability and reliability in various environments.
