Gowanda’s 21M392GLF is a high-quality, reliable molded unshielded RF coil designed for various electronic applications. This component, part of the 21M series, features a compact design with dimensions of 14.224 × 5.588 × 5.588 mm and weighs 1.7 grams. It is suitable for through-hole technology (THT) mounting and is classified under the COTS application grade. The coil offers an inductance of 39 µH with a minimum Q factor of 70, tested at a frequency of 2.5 MHz. It has a direct current resistance (DCR) of 2 ohms and a self-resonant frequency (SRF) of 18 MHz, with a current rating of 0.224 A DC. The dielectric withstanding voltage (DWV) is rated at 1000, 200, and it maintains a tolerance of ±2%. The termination type is RoHS compliant with a Sn/Cu finish, and the core is made of powdered iron. Operating efficiently within a temperature range of -55°C to +105°C, this component is packaged in tape and reel (T&R) format, is fungal inert, and has a moisture sensitivity level (MSL) of 1.
