Gowanda’s 18M181JLF is a high-quality molded unshielded RF coil designed for reliable performance in various electronic applications. This component, 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 under the Commercial Off-The-Shelf (COTS) application grade. The coil offers an inductance of 1.8 µH with a Q minimum of 30 and operates at a test frequency of 7.9 MHz. It has a direct current resistance (DCR) of 0.74 Ω and a self-resonant frequency (SRF) of 150 MHz, with a current rating of 0.58 A DC. The component is designed to withstand a dielectric withstanding voltage (DWV) of 200 and has a tolerance of ±5%. It features RoHS-compliant termination with a Sn/Cu finish and a phenolic core. The coil operates efficiently within a temperature range of -55°C to +125°C, has a moisture sensitivity level (MSL) of 1, and is packaged in tape and reel (T&R) format. Additionally, it is fungal inert, ensuring durability and reliability in demanding environments.
