Gowanda’s 21M222J is a high-quality molded unshielded RF coil designed for reliable performance in various electronic applications. With a weight of 1.7 grams and dimensions of 14.224 × 5.588 × 5.588 mm, this component is part of the 21M series and features through-hole technology (THT) for mounting. It is suitable for commercial off-the-shelf (COTS) applications, offering an inductance of 22 µH and 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 can withstand a dielectric withstanding voltage (DWV) of 1000, 200 and operates within a temperature range of -55°C to +105°C. The component has a tolerance of ±5% and features lead-based (Pb) terminations with a Sn63Pb37 finish. Constructed with a powdered iron core, it is not shielded but is fungal inert, ensuring durability and reliability in various environments. The 21M222J is moisture sensitivity level (MSL) 1 and is available in tape and reel (T&R) packaging.
