Technical details and manufacturing context for High-Voltage Resistor Network

Definition
This high-voltage resistor network is a precision component used in voltage measurement divider systems. It consists of multiple resistors arranged in series or series-parallel configurations to proportionally divide high input voltages down to measurable levels. The design prioritizes accuracy, stability, and insulation integrity under high potential conditions. Key materials include a high-voltage ceramic substrate, thick-film or thin-film resistive elements, and high-dielectric encapsulation material. The network is available with a rated voltage from 1 to 100 kV, resistance per element from 1 to 1000 MΩ, and resistance tolerance from ±0.1% to ±1%. Temperature coefficient ranges from ±25 to ±100 ppm/°C over -40 to +85 °C. Rated power per element at 70 °C is 0.1 to 2 W. Dielectric withstanding voltage between terminals and case is 2 to 200 kV, and insulation resistance is at least 10,000 MΩ at 500 V DC. The number of elements can be 2 to 16, with package styles including SIP or DIP, and mounting options through-hole or surface mount. Dimensions range from 20×10×5 mm to 50×25×15 mm, and weight from 5 to 50 g. These values are reference ranges and must be confirmed for the specific model and application. The product complies with IEC 60115-1 as a verification reference, but certification or compliance is not implied. For accurate selection, verify model-specific parameters and standards with the legal manufacturer or supplier.
Working Principle
The resistor network divides high voltage using multiple precision resistors connected in series or series-parallel. The voltage across each resistor is proportional to its resistance, allowing the high input voltage to be scaled down to a measurable level. Special attention is given to voltage ratings, power dissipation, and insulation to prevent breakdown or measurement errors at elevated voltages. The network's design ensures stable performance over temperature and time, maintaining accuracy in measurement circuits.
