Gowanda’s 8M472MLF is a high-quality molded unshielded RF coil designed for reliable performance in various applications. This component, part of the Series 8M, features a compact design with dimensions of 5.08 × 1.98 × 1.98 mm and a weight of 0.25 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 47 µH with a minimum Q factor of 45, tested at a frequency of 2.5 MHz. It has a DC resistance of 8.2 Ω and a self-resonant frequency of 12.5 MHz, with a current rating of 0.076 A DC. The dielectric withstanding voltage (DWV) is rated at 1000, 200, and it has a tolerance of ±20%. The termination type is RoHS compliant with a Sn/Cu finish, and the core is made of powdered iron. Although it is not shielded, it operates efficiently within a temperature range of -55°C to +105°C and has a moisture sensitivity level (MSL) of 1. Packaged in tape and reel (T&R) format, the 8M472MLF is also fungal inert, ensuring durability and reliability in demanding environments.
