Gowanda’s 28M123MLF 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 tailored for through-hole technology (THT) mounting and is classified under the Commercial Off-The-Shelf (COTS) application grade. With an inductance of 120 µH and a minimum Q factor of 95, it operates efficiently at a test frequency of 0.79 MHz. The coil has a DC resistance of 4.1 Ω and a self-resonant frequency of 10 MHz, supporting a current rating of 0.195 A DC. It is built with a powdered iron core and is not shielded, offering a dielectric withstanding voltage (DWV) of 1000, 200. The component is RoHS compliant with a Sn/Cu termination finish, and it maintains performance across a wide operating temperature range from -55°C to +125°C. Additionally, it is packaged in tape and reel (T&R) format, has a moisture sensitivity level (MSL) of 1, and is fungal inert, ensuring durability and reliability in demanding environments.
