Gowanda’s 21M222KLF is a high-quality, reliable electronic component designed for demanding applications. This molded unshielded RF coil weighs 1.7 grams and measures 14.224 × 5.588 × 5.588 mm. It belongs to the 21M series and is mounted using through-hole technology (THT). Suitable for commercial off-the-shelf (COTS) applications, it offers an inductance of 22 µH with a minimum Q factor of 60 at a test frequency of 2.5 MHz. The coil has a direct current resistance (DCR) of 1 ohm and a self-resonant frequency (SRF) of 24 MHz, with a current rating of 0.326 A DC. It features a dielectric withstanding voltage (DWV) of 1000, 200 and a tolerance of ±10%. The termination type is RoHS compliant with a Sn/Cu finish, and it uses a powdered iron core. Operating within a temperature range of -55°C to +105°C, it is rated at moisture sensitivity level (MSL) 1 and is packaged in tape and reel (T&R) format. Additionally, it is fungal inert, ensuring durability and reliability in various environments.
