By developing the Metal technology including Metal Foil, Metal Strip, Welding ones and combining with the original thin film and thick film technology, Delta has developed a series of current sensing resistor which characterized with miniaturization, high precision, and low TCR. Furthermore, Delta has not only developed a variety of processes which can cover a wide resistance range from 0.2mΩ to 10Ω, also can provide the most suitable resistance and rated power based on customer needs.
