Gowanda’s 18M680M is a high-quality, reliable electronic component designed for demanding applications. This molded unshielded RF coil, part of the 18M series, features a compact design with dimensions of 11.125 × 4.775 × 4.775 mm and a weight of 0.95 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 0.68 µH with a minimum Q factor of 45, tested at a frequency of 25 MHz. It has a direct current resistance (DCR) of 0.15 Ω and a self-resonant frequency (SRF) of 250 MHz, with a current rating of 1.3 A DC. The device can withstand a dielectric withstanding voltage (DWV) of 200 and operates within a temperature range of -55°C to +125°C. It features a lead-based termination type with a Sn63Pb37 finish and a phenolic core, ensuring durability and performance. The component is fungal inert, has a moisture sensitivity level (MSL) of 1, and is available in tape and reel (T&R) packaging.
