Gowanda’s 18M330MLF is a high-quality molded unshielded RF coil designed for reliable performance in demanding applications. Weighing 0.95 grams and measuring 11.125 × 4.775 × 4.775 mm, this component is part of the 18M series and features through-hole technology (THT) mounting. It is suitable for commercial off-the-shelf (COTS) applications, offering an inductance of 333 µH with a minimum Q factor of 65 at a test frequency of 2.5 MHz. The coil has a DC resistance of 2.75 ohms and a self-resonant frequency of 22 MHz, with a current rating of 2 A DC. It is constructed with a powdered iron core and has a dielectric withstanding voltage (DWV) of 200. The component is RoHS compliant with a Sn/Cu termination finish, operates within a temperature range of -55°C to +125°C, and is packaged in tape and reel (T&R) format. Additionally, it is fungal inert and has a moisture sensitivity level (MSL) of 1.
