Gowanda’s 21M680KLF is a high-quality molded unshielded RF coil designed for reliable performance in various electronic applications. This component, part of the 21M series, features a compact design 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 as a commercial off-the-shelf (COTS) application grade. The coil offers an inductance of 0.68 µH with a minimum Q factor of 65, tested at a frequency of 25 MHz. It has a direct current resistance (DCR) of 0.08 Ω and a self-resonant frequency (SRF) of 240 MHz, supporting a current rating of 1.7 A DC. The component is designed to withstand dielectric withstanding voltages (DWV) of 1000 and 200, with a tolerance of ±10%. It features RoHS-compliant Sn/Cu termination finishes and a phenolic core, operating efficiently within a temperature range of -55°C to +125°C. The product is moisture sensitivity level (MSL) 1 rated, packaged in tape and reel (T&R) format, and is fungal inert, ensuring durability and reliability in demanding environments.
