Gowanda’s 8M181KLF is a high-quality, reliable molded unshielded RF coil designed for various electronic applications. Weighing just 0.25 grams, it features compact dimensions of 5.08 × 1.98 × 1.98 mm and is part of the 8M series. This component is suitable for through-hole technology (THT) mounting and is classified as a commercial off-the-shelf (COTS) application grade. It offers an inductance of 1.8 µH with a minimum Q factor of 40, tested at a frequency of 7.9 MHz. The coil has a direct current resistance (DCR) of 0.56 Ω and a self-resonant frequency (SRF) of 135 MHz, with a current rating of 0.29 A DC. It is designed to withstand dielectric withstanding voltages (DWV) of 1000 and 200, with a tolerance of ±10%. The termination type is RoHS compliant with a Sn/Cu finish, and the core is made of powdered iron. Operating within a temperature range of -55°C to +105°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.
