Which high-voltage resistors are the right ones: Variants & possible applications

High-voltage resistors ensure that voltages are regulated. They enable precise measurement and thus increase safety in the vicinity of electrical systems. Each design and each voltage range offers specific advantages and can be optimally tailored to different applications. 

This article provides an overview of the three most important types of high-voltage resistors and shows the areas of application in which they demonstrate their strengths.

 

1. Cylindrical high-voltage resistors: Robust and versatile

Cylindrical high-voltage resistors are among the most commonly used designs. Their construction allows for a compact design with high voltage and power resistance. Thanks to their robust structure, they are ideal for applications where reliability and long service life are crucial.

 

Typical advantages

  • Compact cylindrical shape that can be easily integrated into existing systems
  • High resistance to stress and temperature
  • Reliable performance even under demanding conditions
  • Wide range of different coating options available

 

Areas of application

  • Test equipment and measurement systems
  • Power supply and energy technology
  • Industrial electronics and automation
  • Medical technology

2. Flat resistors for high voltage: Space-saving and adaptable

Flat high-voltage resistors offer an ideal solution when compact designs are required. Their flat design makes them particularly suitable for integration into devices with limited space. In addition, their geometry enables efficient heat dissipation, which keeps operation stable even at higher power levels.

 

Typical advantages

  • Flat design for space-saving integration
  • Excellent heat dissipation for consistent performance
  • Flexibly adaptable to customer-specific designs

 

Areas of application

  • Medical technology, e.g., in imaging systems
  • High-voltage power supplies and power electronics
  • Industrial automation systems
  • Aviation technology

3. Ultra-high-precision resistors: When accuracy counts

When maximum accuracy and long-term stability are required, ultra-high-precision resistors are the right choice. They are characterized by minimal tolerances and excellent temperature and long-term stability. These high-voltage resistors deliver consistently reliable measurements even in sensitive applications.

 

Typical advantages

  • Extremely low tolerances for precise results
  • Excellent stability under changing temperatures
  • Long-term stability even under continuous load

 

Areas of application

  • High-precision measurement technology and research
  • Medical technology with sensitive measurement systems
  • Industrial applications with the most stringent accuracy requirements
  • Power supply and voltage supply equipment

Selection criteria: Which high-voltage resistor is suitable for my application?

The choice of the right high-voltage resistor depends heavily on individual requirements.

 

Important factors when selecting

  • Load capacity: What stresses must the resistor be able to withstand continuously?
  • Design: Is a compact installation space required?
  • Accuracy: Is a standard resistor sufficient, or is a high-precision solution required?
  • Environment: What temperatures and external conditions can be expected in the operating environment?

 

An example: In medical technology, compact flat resistors that can be installed in tightly dimensioned devices are often required. In energy technology, on the other hand, robustness plays a decisive role, so cylindrical high-voltage resistors are preferred. For precise measurement tasks in research and industry, ultra-high-precision resistors are used.

Conclusion: The right high-voltage resistor for every application

There is a suitable high-voltage resistor for every requirement, whether robust, space-saving, or high-precision:

  • Cylindrical resistors are a reliable choice for versatile applications.
  • Flat resistors impress with their compact design and efficient heat dissipation.
  • Ultra-high-precision resistors guarantee maximum accuracy.


The decision for the right variant depends on factors such as load capacity, design, accuracy, and operating environment. By taking the appropriate criteria into account, you can ensure that systems work reliably and deliver stable results in the long term.
