Dayi Technology (TA-I) is one of the major brand manufacturers of SMD chip resistors, with its main core product being current sensing resistors. Dayi's current sensing resistors are widely used in battery protection boards, BMS, car lights, laptop peripherals, new energy and other products, with a wide range of products. Dayi's current sensing resistors have excellent temperature coefficients and high rated power (0.5W~5W), providing a lower resistance value of 0.3mohm, and have a variety of choices, such as long electrodes, four terminals, etc. By using current control to ensure the safety of circuits and power operation monitoring systems, they comply with AEC-Q200 certification standards.
