Gowanda’s 15M391GLF is a high-quality, reliable molded unshielded RF coil designed for demanding applications. Weighing 0.65 grams and measuring 9.525 × 3.962 × 3.962 mm, this component is part of the 15M series and is suitable for through-hole technology (THT) mounting. It is classified as a Commercial Off-The-Shelf (COTS) application grade, offering an inductance of 3.9 µH with a minimum Q factor of 33 at a test frequency of 7.9 MHz. The coil features a direct current resistance (DCR) of 2.3 ohms and a self-resonant frequency (SRF) of 100 MHz, with a current rating of 0.28 A DC. It can withstand a dielectric withstanding voltage (DWV) of 1000 volts and maintains a tolerance of ±3%. The termination type is RoHS compliant with a Sn/Cu finish, and the core is made of phenolic material. Operating efficiently in temperatures ranging from -55°C to +125°C, the component is rated at moisture sensitivity level (MSL) 1 and is packaged in tape and reel (T&R) format. Additionally, it is fungal inert, ensuring durability and reliability in various environments.
