Serpentine Pattern Design Achieves Impulse High Power Voltage Resistors (RI80).
The tubular RI80 high voltage precision resistors were specifically designed for general purpose high voltage systems in industrial. The RI80 uses Direct's proprietary thick film Metal Glaze resistive element and Serpentine Pattern Design which provides ideal cost efficient, stability, precision and high voltage characteristics for a wide range of measurement, voltage divider circuits, and control functions in high voltage power electronics applications.
Direct RI80 Precision Voltage Resistors are able to absorb large amounts of energy at high voltage while remaining non-inductive and heavy load characteristics. The RI80 conforms to the RoHS directives and Lead-free. Customed design, and tighter tolerances are available on request.
By utilizing specific ceramic core materials with optimum processing, Direct are able to control, very tightly in manufacturing, the important ultra-stable performance parameters in operating temperatures from -55°C to +70°C.
(RI80) can handle up to 35KV voltage. This unique process is offered in specific resistance values in a wide variety of sizes and terminations. The extraordinary operating stability of the Type RI80 resistors will improve the performance of your high voltage system.
The RI80 Precision Voltage Series is for customed designs, tighter tolerances, non-standard technical requirements, or custom special applications, please contact our sales for more information.
