1.Introduction
High voltage ceramic resistors are essential components in various high voltage applications, providing stability and efficiency.

2.Applications
These resistors are used in:

Power supplies

Generators

Transformers

High-voltage transmission lines

3.Key Features
Non-inductive: They maintain a constant resistance regardless of the applied voltage, ensuring consistent performance.
High voltage resistance: Capable of withstanding high working voltages, often reaching up to 48 kV or more.
Excellent stability: Their resistance remains stable over a wide range of temperatures and frequencies.

4.Materials
High voltage ceramic resistors are typically made from a blend of alumina, and carbide derivative, pressed into the desired shape.

5.Advantages
Durability: Withstand high energy pulses and impulse voltages without degradation.
Space-saving: Bulk construction allows for uniform energy distribution, reducing the risk of arcing in high-voltage designs.
Selection Tips
Voltage rating: Choose a resistor with a high voltage rating that matches the application requirements.
Lead spacing: Ensure adequate lead spacing to prevent arcing in high-voltage designs.
Temperature coefficient: Consider the temperature coefficient of resistance (TCR) to ensure accurate readings, especially when measuring current flow by voltage drop.
