Technical details and manufacturing context for High-Voltage Resistor Network

Definition
A precision component within a Voltage Measurement Divider system that consists of multiple resistors arranged in a specific configuration to safely reduce high voltages to measurable levels while maintaining accuracy, stability, and insulation integrity under high potential conditions.
Working Principle
Utilizes multiple precision resistors connected in series or series-parallel configurations to divide high input voltages proportionally according to resistor ratios, with special attention to voltage ratings, power dissipation, and insulation to prevent breakdown or measurement errors at elevated voltages.
Common Materials
High-voltage ceramic substrate, Thick-film or thin-film resistive elements, High-dielectric encapsulation material
Technical Parameters
  • Maximum working voltage rating (kV) Customizable
Components / BOM
  • High-Voltage Resistor Elements
    Provide precise resistance values while withstanding high voltage stress
    Material: Thick-film or thin-film resistive material on ceramic
  • Insulating Substrate
    Provides electrical isolation between resistor elements and mechanical support
    Material: High-alumina ceramic or specialized PCB material
  • Protective Encapsulation
    Prevents arcing, moisture ingress, and provides mechanical protection
    Material: High-dielectric epoxy or silicone compound
  • Termination Pads
    Electrical connection points for circuit integration
    Material: Silver-palladium or gold plating
Engineering Reasoning
1-100 kV DC, 0.1-10 mA current, -40°C to +125°C ambient temperature
Dielectric breakdown at 120 kV DC (electric field strength > 12 kV/mm), thermal runaway at 150°C junction temperature, power dissipation > 2 W per resistor element
Design Rationale: Dielectric breakdown of insulating substrate (alumina ceramic) when electric field exceeds 12 kV/mm, thermal runaway due to positive temperature coefficient of resistance (TCR > 200 ppm/°C) causing localized heating, electromigration at current densities > 10^6 A/cm²
Risk Mitigation (FMEA)
Trigger Voltage transient exceeding 150% rated voltage (150 kV for 100 kV rated network)
Mode: Dielectric breakdown causing short circuit between resistor elements
Strategy: Cascaded resistor topology with distributed voltage grading, parallel transient voltage suppression diodes with 5 ns response time
Trigger Continuous power dissipation exceeding 2 W per resistor element at 85°C ambient
Mode: Thermal runaway leading to resistance drift > 10% and eventual open circuit
Strategy: Thermal vias to copper heat spreader (thermal resistance < 20°C/W), pulse derating to 50% of DC rating for > 1 ms pulses
