Gowanda’s 8M331MLF is a high-quality, reliable molded unshielded RF coil designed for various applications. Weighing just 0.25 grams and measuring 5.08 × 1.98 × 1.98 mm, this component is part of the 8M series and features a through-hole mounting type (THT). It is suitable for commercial off-the-shelf (COTS) applications, offering an inductance of 3.3 µH with a minimum Q factor of 45 at a test frequency of 7.9 MHz. The coil has a direct current resistance (DCR) of 1.2 ohms and a self-resonant frequency (SRF) of 100 MHz, with a current rating of 0.198 A DC. It is designed to withstand a dielectric withstanding voltage (DWV) of 1000, 200 and operates within a temperature range of -55°C to +105°C. The component is RoHS compliant, with a Sn/Cu termination finish and a powdered iron core. It is packaged in tape and reel (T&R) format, has a moisture sensitivity level (MSL) of 1, and is fungal inert.
