Gowanda’s 8M471K is a high-quality, reliable molded unshielded RF coil designed for various electronic applications. Weighing just 0.25 grams, this component features compact dimensions of 5.08 × 1.98 × 1.98 mm and is part of the Series 8M. It is a through-hole technology (THT) component with a commercial off-the-shelf (COTS) application grade, offering an inductance of 4.7 µH and a minimum Q factor of 55. The coil operates at a test frequency of 7.9 MHz, with a DC resistance of 2.1 Ω and a self-resonant frequency of 88 MHz. It supports a current rating of 0.15 A DC and a dielectric withstanding voltage (DWV) of 1000, 200. The component has a tolerance of ±10% and features a lead-based termination type with a Sn63Pb37 finish. Constructed with a powdered iron core, it is designed to operate in temperatures ranging from -55°C to +105°C and has a moisture sensitivity level (MSL) of 1. Packaged in tape and reel (T&R) format, the 8M471K is also fungal inert, ensuring durability and reliability in various environments.
