Gowanda’s 28M472J is a high-quality, reliable molded unshielded RF coil designed for 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 the Commercial Off-The-Shelf (COTS) application grade. With an inductance of 47 µH and a minimum Q factor of 65, it operates efficiently at a test frequency of 2.5 MHz. The coil has a direct current resistance (DCR) of 1 Ω and a self-resonant frequency (SRF) of 16 MHz, supporting a current rating of 0.39 A DC. It is designed to withstand dielectric withstanding voltages (DWV) of 1000 and 200, with a tolerance of ±5%. The termination type is lead-based with a Sn63Pb37 finish, and the core is made of powdered iron. The component is not shielded but is fungal inert, ensuring durability in various environments. It operates within a temperature range of -55°C to +125°C and has a moisture sensitivity level (MSL) of 1, making it suitable for tape and reel (T&R) packaging.
