High Voltage Resistors

Our high voltage resistors are designed for demanding HV applications where stable resistance, high voltage capability, and reliable energy handling are essential. We offer high voltage resistors in 5W, 15W, 50W, and 100W power ratings, suitable for use in voltage dividers, HV measurement circuits, pulse discharge systems, capacitor discharge circuits, and general high voltage power electronics. For the lower wattage range, we also offer high precision resistor options with 1% tolerance, making them especially useful where accurate voltage division, predictable grading, or measurement stability is important.

High voltage resistors are commonly used as ballast resistors to limit pulse current in spark gaps, plasma systems, capacitor banks, and other pulse applications. They are also well suited for DC grading networks in stacked MOSFET switches, where multiple resistors are used to distribute voltage evenly across the switch chain. The glass glaze construction, thick-film resistive element, and low-inductance design make these resistors a practical choice for both DC and pulsed high voltage circuits, including research equipment, impulse generators, electrostatic systems, and custom high voltage experiments.

If you cannot find the specific high voltage resistor, resistance value, voltage rating, power rating, tolerance, or package style you are looking for, please contact us, and we will try to source it through our trusted suppliers.
