Gowanda’s 18M821KLF is a high-quality molded unshielded RF coil designed for reliable performance in various electronic applications. Weighing 0.95 grams and measuring 11.125 × 4.775 × 4.775 mm, this component is part of the 18M series and features through-hole technology (THT) for mounting. It is suitable for commercial off-the-shelf (COTS) applications, offering an inductance of 8.2 µH with a minimum Q factor of 30 at a test frequency of 7.9 MHz. The coil has a direct current resistance (DCR) of 0.44 Ω and a self-resonant frequency (SRF) of 48 MHz, with a current rating of 0.54 A DC. It can withstand a dielectric withstanding voltage (DWV) of 200 volts and maintains a tolerance of ±10%. The component is RoHS compliant with a Sn/Cu termination finish and features a powdered iron core. It operates effectively in temperatures ranging from -55°C to +125°C, has a moisture sensitivity level (MSL) of 1, and is packaged in tape and reel (T&R) format. Additionally, it is fungal inert, ensuring durability and reliability in diverse environments.
