Overview
Overview
The high-voltage resistor series uses specialized resistance materials and multi-layer insulation design to operate stably under thousands or even hundreds of thousands of volts — delivering excellent dielectric strength, pulse capability and an extremely low voltage coefficient (VCR). Widely used in X-ray / CT imaging, high-voltage power supplies, energy-storage discharge, lightning surge protection, HV measurement instruments, laser power supplies, electrical testing and other critical applications requiring stable, reliable HV components.
Key Features
Ultra-High Voltage Capability
- Working voltage 1kV ~ 100kV+
- Transient withstand 2× nominal
Low Voltage Coefficient (Low VCR)
- VCR ≤ 5 ppm/V — stable resistance under HV
- Ideal for precision measurement and HV dividers
High Pulse & Discharge Tolerance
- Withstands tens of joules of single-pulse energy
- Suitable for X-ray, laser and energy-storage discharge applications
Multi-Layer Insulation
- Epoxy / silicone / ceramic composite insulation
- Anti-creep and anti-partial-discharge (PD) design
Wide Operating Temperature Range
- Operating temperature -55°C ~ +200°C
- Suitable for thermal-cycling and vibration environments
Flexible Customization & Packaging
- Cylindrical, planar (chip) and modular packages
- Custom resistance, leads and form factors
