Gowanda’s 15M303J is a high-quality, reliable molded unshielded RF coil designed for various electronic applications. This component, part of the 15M series, features a compact design with dimensions of 9.525 × 3.962 × 3.962 mm and a weight of 0.65 g. It is suitable for through-hole technology (THT) mounting and is classified as a Commercial Off-The-Shelf (COTS) application grade. The coil offers an inductance of 300 µH with a minimum Q factor of 65, tested at a frequency of 0.79 MHz. It has a direct current resistance (DCR) of 11.5 Ω and a self-resonant frequency (SRF) of 5.4 MHz, with a current rating of 0.083 A DC. The dielectric withstanding voltage (DWV) is rated at 1000, with a tolerance of ±5%. 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 effectively within a temperature range of -55°C to +125°C. It has a moisture sensitivity level (MSL) of 1, is packaged in tape and reel (T&R), and is fungal inert, ensuring durability and reliability in various environments.
