Gowanda’s 28M561JLF is a high-quality molded unshielded RF coil designed for reliable performance in various electronic applications. This component, part of the 28M series, features a compact design with dimensions of 22.86 × 7.137 × 7.137 mm and a weight of 2.65 g. It is suitable for through-hole technology (THT) mounting and is classified under Commercial Off-The-Shelf (COTS) application grade. With an inductance of 5.6 µH and a minimum Q factor of 60, it operates efficiently at a test frequency of 7.9 MHz. The coil has a direct current resistance (DCR) of 0.745 Ω and a self-resonant frequency (SRF) of 80 MHz, supporting a current rating of 0.745 A DC. It is designed to withstand dielectric withstanding voltages (DWV) of 1000 and 200, with a tolerance of ±5%. The termination type is RoHS compliant with a Sn/Cu finish, and the core is made of phenolic material. Operating within a temperature range of -55°C to +105°C, it is rated at moisture sensitivity level (MSL) 1 and is packaged in tape and reel (T&R) format. Additionally, the component is fungal inert, ensuring durability and reliability in diverse environments.
