This article aims to provide an overview of high voltage resistors, their key characteristics, and a detailed examination of popular product models from leading manufacturers.
High voltage resistors are defined by their ability to operate at elevated voltage levels, typically above 1,000 volts. The key specifications that characterize these resistors include:
1. **Voltage Ratings**: High voltage resistors are rated for specific voltage levels, which indicate the maximum voltage they can safely handle without breaking down or failing.
2. **Power Ratings**: This refers to the maximum power the resistor can dissipate without overheating. It is crucial to select a resistor with an appropriate power rating to ensure reliable operation.
When selecting high voltage resistors, several characteristics and specifications should be considered:
1. **Tolerance**: This indicates the precision of the resistor's value. A lower tolerance means higher accuracy, which is essential in applications where precise resistance values are critical.
2. **Temperature Coefficient**: This specification describes how the resistance value changes with temperature. A low temperature coefficient is desirable for applications requiring stable performance across varying temperatures.
3. **Material Composition**: High voltage resistors can be made from various materials, including carbon, metal film, and wire-wound constructions. The choice of material affects the resistor's performance, stability, and reliability.
