Power Resistor - Applications and Advantages

High power resistors for demanding industrial applications are core systems in industrial power electronics. The resistors are usually mounted directly on the heat sink to prevent them from overheating.

But what exactly are power resistors?
What advantages do they offer and for which applications are they used?

This article highlights the key aspects and shows why these components are indispensable.

What are thick-film Power Resistors?

Power resistors - in particular low-inductance thick-film power resistors - are essential for the efficient transmission of direct-current-based energy generated in power stations, for example.

They are characterized by their compact design, which makes them ideal for use in confined spaces. They can be used in a wide range of applications because of their small size and high performance.

To meet specific requirements, they also offer flexible customization options.

They are available in

  • various power levels
  • sizes
  • tolerances 
  • ohmic values

 

What are the advantages of Power Resistors?

Power resistors offer numerous advantages that make them a preferred choice for many applications:

  • Variable configurations:
    Power resistors are available in various configurations, and single internal resistor to various connection options.
     
  • Wide power spectrum:
    Ranging from 18 W to 3,000 W, they offer a high degree of flexibility for various areas of application.
     
  • Compact and flexible:
    Despite their small size, these resistors are characterized by high performance and easy installation. Depending on the series, various connection options are available, such as screw contacts, fast-on terminals, cable connections and solder pin contacts.
     
  • Long-term reliability:
    Power resistors achieve the highest power density, a large part of the heat dissipated can be transferred to a defined cooling system by a very efficient thermal connection. And have a long service life.
