Description
High Voltage Thick Film Resistors for Capacitor Charging & Inverter Soft Start
Product Overview
High voltage thick film resistors are specially designed for demanding applications, including capacitor charging and discharging, inverter soft start, and high-voltage dummy loads. Moreover, thanks to their non-inductive construction and excellent insulation resistance, these resistors consistently deliver stable and reliable performance under extreme voltage conditions ranging from 10kV to 50kV.
Key Features
The RI80 high-voltage resistor has no inductive reactance and offers excellent stability. As a result, it is widely used in AC or pulse circuits and various types of high-voltage equipment. In addition, it is suitable for micro-current measurement circuits due to its high resistance and precision. Despite its compact size and lightweight structure, the RI80 supports a large working voltage and exhibits strong high-frequency characteristics, making it ideal for demanding or space-limited applications.
