The HVR series of cylindrical resistors are designed to operate at high voltages at an economical price. The HVR resistor is available with silicone[S] coating or epoxy[E] coating. The epoxy coated models have excellent humidity protection. A wide range of tolerances and TCRs are available in both types. Applications include: Automated Tests, Gas Chromatography, Military Radar, Capacitor Charging, Electrophoresis, Electron Beams, Medical (Imaging, PET, X-Ray, MRI), Lasers, Voltage Dividers, Image Intensifiers, Surface Analysis, Microwaves, Ion Sources. |
