Gowanda’s 8M391M Molded Unshielded RF Coils are high-quality electronic components designed for reliable performance in various applications. These coils, part of the 8M series, feature a compact design with dimensions of 5.08 × 1.98 × 1.98 mm and a weight of 0.25 g. They are tailored for through-hole technology (THT) mounting and are classified as commercial off-the-shelf (COTS) application grade. With an inductance of 3.9 µH and a minimum Q factor of 50, these coils operate efficiently at a test frequency of 7.9 MHz. They have a direct current resistance (DCR) of 1.5 Ω and a self-resonant frequency (SRF) of 95 MHz, supporting a current rating of 0.178 A DC. The dielectric withstanding voltage (DWV) is rated at 1000, 200, with a tolerance of ±20%. The coils use a powdered iron core and are finished with Sn63Pb37 termination, ensuring durability and performance across a wide operating temperature range of -55°C to +105°C. They are packaged in tape and reel (T&R) format, have a moisture sensitivity level (MSL) of 1, and are fungal inert, making them suitable for various demanding environments.
