Gowanda’s 18M471G is a high-quality, reliable molded unshielded RF coil designed for various electronic applications. This component, part of the 18M series, features a compact design with dimensions of 11.125 × 4.775 × 4.775 mm and a weight of 0.95 g. It is suitable for through-hole technology (THT) mounting and is classified under the Commercial Off-The-Shelf (COTS) application grade. The coil offers an inductance of 4.7 µH with a minimum Q factor of 30, tested at a frequency of 7.9 MHz. It has a direct current resistance (DCR) of 0.21 Ω and a self-resonant frequency (SRF) of 60 MHz, with a current rating of 0.745 A DC. The dielectric withstanding voltage (DWV) is 200, and it maintains a tolerance of ±2%. The termination type is lead-based with a Sn63Pb37 finish, and the core is made of powdered iron. The component is not shielded and operates efficiently within a temperature range of -55°C to +125°C. It has a moisture sensitivity level (MSL) of 1 and is packaged in tape and reel (T&R) format. Additionally, it is fungal inert, ensuring durability and reliability in various environments.
