High voltage resistors are characterized by several key features that distinguish them from standard resistors:
1. **Voltage Rating**: High voltage resistors are designed to withstand high voltage levels, typically exceeding 1 kV. This capability is crucial for applications where electrical stress is significant.
2. **Power Rating**: The power rating indicates the maximum power the resistor can dissipate without overheating. High voltage resistors are engineered to handle substantial power levels, ensuring they can operate safely in demanding environments.
3. **Temperature Coefficient**: This characteristic refers to how the resistance value changes with temperature. High voltage resistors are designed to maintain stability across a range of temperatures, which is vital for consistent performance.
There are several types of high voltage resistors, each suited for specific applications:
1. **Wirewound Resistors**: These resistors are made by winding a wire around a core. They offer high precision and stability, making them ideal for applications requiring accurate resistance values.
2. **Film Resistors**: Thin or thick film resistors are created by depositing a resistive film on a substrate. They are known for their compact size and are commonly used in electronic circuits.
3. **Ceramic Resistors**: These resistors are made from ceramic materials, providing excellent thermal stability and high voltage handling capabilities. They are often used in high-power applications.
4. **Thick and Thin Film Resistors**: These resistors are manufactured using different techniques to achieve varying levels of precision and power handling. Thin film resistors offer higher accuracy, while thick film resistors are more robust.
