UP1B-1R0-R is a miniature surface mount power inductor designed for high-current, low-inductance applications. It features a rated inductance of 1.0 µH (±20%) with an RMS current rating of 4.4 A and saturation current of 5.3 A, delivering maximum power density in a compact package. The inductor utilizes ferrite core material with a protective case to eliminate core breakage and meets UL 94V-0 flammability standards. With a DC resistance of 0.0177 O maximum and operating temperature range from -40°C to +85°C, it is ideal for board-level and industrial DC-DC converter applications requiring reliable energy storage and filtering in space-constrained designs.
