21M221JLF

Gowanda’s 21M221JLF is a high-quality molded unshielded RF coil designed for reliable performance in various electronic applications. Weighing 1.7 grams and measuring 14.224 × 5.588 × 5.588 mm, this component is part of the 21M series and features through-hole technology (THT) mounting. It is suitable for commercial off-the-shelf (COTS) applications, offering an inductance of 2.2 µH with a minimum Q factor of 40 at a test frequency of 7.9 MHz. The coil has a direct current resistance (DCR) of 0.5 ohms and a self-resonant frequency (SRF) of 135 MHz, with a current rating of 0.68 A DC. It can withstand dielectric withstanding voltages (DWV) of 1000 and 200 volts, with a tolerance of ±5%. The termination is RoHS compliant with a Sn/Cu finish, and the core is made of phenolic material. Operating efficiently in temperatures ranging from -55°C to +125°C, the coil is packaged in tape and reel (T&R) and is fungal inert, ensuring durability and reliability in demanding environments.
