What are the HVE Series High Voltage Thick Film Tubular Resistors?
The HVE series is a range of high voltage thick film resistors constructed on a tubular ceramic substrate, intended for chassis-level and panel-mounted installations where both elevated working voltages and significant power dissipation must be managed simultaneously. Power ratings span 2.5W to 20W, and the series is rated for supply voltages from 4.8kV up to 45kV, placing it squarely in the range demanded by industrial electrostatic systems, high voltage power supplies, and discharge networks where SMD or small axial components would be entirely unsuitable. The tubular ceramic body provides the physical length and creepage distance necessary to prevent surface flashover at these voltage levels, while the thick film element delivers the resistance stability and moderate TCR characteristic of film technology rather than the inductance of wirewound alternatives.
The resistance range extends from 200Ω to 10GΩ, covering an exceptionally wide span of impedance values within a single product family. Tolerance options of ±1%, ±5%, and ±10% allow the HVE series to be specified across both precision voltage-division duties and general-purpose current-limiting applications without requiring a change of technology. The temperature coefficient of resistance is ±100 ppm/°C across the range, providing predictable resistance behaviour over the thermal excursions typical of industrial equipment. The rated continuous working voltage for each part is determined from the lower of the calculated value derived from power rating and resistance, or the published maximum supply voltage for that body size, ensuring conservative and reliable voltage stress management across the full resistance span.
The tubular form factor distinguishes the HVE series from the SMD chip types and axial leaded components in the RARA high voltage range, and positions it for applications where through-board or chassis mounting is required alongside high standoff voltage. The ceramic tube body provides mechanical robustness, high thermal stability, and the extended surface path needed to support working voltages to 45kV without corona or flashover under normal operating conditions. The HVE series sits within RARA’s broader five-configuration high voltage lineup — alongside SMD chip, axial, planar, and bleeder-divider types — and is manufactured under ISO9001 and IATF16949 certified quality systems.
