Gowanda’s MLRF1812-680K is a high-quality, reliable molded unshielded chip inductor, qualified under M83446/39 standards. This component, weighing 0.301 grams and measuring 4.22 × 3 × 3 mm, is part of the MLRF1812 series and is designed for surface mount technology (SMT) applications. It features an inductance of 0.68 µH, a direct current resistance (DCR) of 1.4 Ω, and a current rating of 0.379 A DC. The inductor operates at a self-resonant frequency (SRF) of 150 MHz and is tested at 25 MHz with a minimum Q factor of 30. It has a dielectric withstanding voltage (DWV) of 200, 80 and a tolerance of ±10%. The product level is M, with lead-based (Pb) termination and a Sn63Pb37 finish. Constructed with a powdered iron core, it is not shielded and can operate in temperatures ranging from -55°C to +125°C. It has a moisture sensitivity level (MSL) of 1, is packaged in tape and reel (T&R), and is fungal inert.
