Gowanda’s 21M820KLF is a high-quality molded unshielded RF coil designed for reliable performance in various applications. This component, part of the 21M series, features a compact size with dimensions of 14.224 × 5.588 × 5.588 mm and a weight of 1.7 g. It is suitable for through-hole technology (THT) mounting and is classified under the COTS application grade. With an inductance of 0.82 µH and a minimum Q factor of 65, it operates efficiently at a test frequency of 25 MHz. The coil has a direct current resistance (DCR) of 0.11 Ω and a self-resonant frequency (SRF) of 220 MHz, supporting a current rating of 1.52 A DC. It is designed to withstand a dielectric withstanding voltage (DWV) of 1000, 200 and offers a tolerance of ±10%. The termination type is RoHS compliant with a Sn/Cu finish, and the core is made of phenolic material. Operating reliably in temperatures ranging from -55°C to +125°C, it has a moisture sensitivity level (MSL) of 1 and is packaged in tape and reel (T&R) format. Additionally, the component is fungal inert, ensuring durability in various environments.
