Gowanda’s 21M821KLF is a high-quality molded unshielded RF coil designed for reliable performance in various electronic applications. Weighing 1.7 grams, this component features dimensions of 14.224 × 5.588 × 5.588 mm and is part of the 21M series. It is suitable for through-hole technology (THT) mounting and is classified under the Commercial Off-The-Shelf (COTS) application grade. With an inductance of 8.2 µH and a minimum Q factor of 35, it operates at a test frequency of 7.9 MHz. The coil has a DC resistance of 0.22 ohms and a self-resonant frequency of 44 MHz, supporting a current rating of 0.68 A DC. It boasts a dielectric withstanding voltage of 1000, 200 and a tolerance of ±10%. The termination type is RoHS compliant with a Sn/Cu finish, and the core is made of powdered iron. Although unshielded, it operates efficiently within a temperature range of -55°C to +105°C and has a moisture sensitivity level of 1. Packaged in tape and reel (T&R), it is also fungal inert, ensuring durability and reliability in diverse environments.
