Gowanda’s 28M682KLF is a high-quality molded unshielded RF coil designed for reliable performance in various electronic applications. With a weight of 2.65 grams and dimensions of 22.86 × 7.137 × 7.137 mm, this component is part of the 28M series and features through-hole technology (THT) for mounting. It is suitable for commercial off-the-shelf (COTS) applications, offering an inductance of 68 µH and a minimum Q factor of 75 at a test frequency of 2.5 MHz. The coil has a direct current resistance (DCR) of 1.85 ohms and a self-resonant frequency (SRF) of 13 MHz, with a current rating of 0.285 A DC. It is designed to withstand dielectric withstanding voltages (DWV) of 1000 and 200 volts, with a tolerance of ±10%. The component is RoHS compliant, featuring a Sn/Cu termination finish and a powdered iron core. It operates effectively within a temperature range of -55°C to +125°C and is rated at moisture sensitivity level (MSL) 1. Packaged in tape and reel (T&R) format, the 28M682KLF is also fungal inert, ensuring durability and reliability in demanding environments.
