wirewound,power A flat tubular ceramic has two terminals and is wound with either copper wire or chromium alloy wire as a resistance element. It is coated with a high-temperature non-flammable resin. When cooled and dried, it is encapsulated in insulation through a high-temperature process before the final installation of the component mounts. It is mainly utilized for industrial installations where height is limited. Features excellent windings, taps adding, low impedance, and PC board insertable. These resistors are suitable for educational modeling applications, load testing, industrial machinery, electric power distribution, instruments, automation control installations, etc. For custom specifications, please contact us to discuss the details.
