Gowanda’s 18M330J is a high-quality molded unshielded RF coil designed for reliable performance in various electronic applications. With a weight of 0.95 grams and dimensions of 11.125 × 4.775 × 4.775 mm, this component is part of the 18M series and features through-hole technology (THT) for mounting. It is suitable for commercial off-the-shelf (COTS) applications, offering an inductance of 0.33 µH and a minimum Q factor of 50 at a test frequency of 25 MHz. The coil has a direct current resistance (DCR) of 0.065 ohms and a self-resonant frequency (SRF) of 350 MHz, with a current rating of 2 A DC. It can withstand a dielectric withstanding voltage (DWV) of 200 volts and has a tolerance of ±5%. The termination type is lead-based (Pb) with a Sn63Pb37 finish, and the core material is phenolic. The component is not shielded and operates within a temperature range of -55°C to +125°C, with a moisture sensitivity level (MSL) of 1. It is packaged in tape and reel (T&R) format and is fungal inert.
