Chassis Mount Resistors

Chassis mount resistors, also called panel-mount fixed resistors, are passive components designed to limit the electricity flow in electrical circuits. These resistors precisely dissipate large amounts of heat and help prevent damage or failure of other circuit components. A chassis mount resistor is constructed with a metal housing, often aluminium, that is designed to be mounted to a chassis or heat sink. Chassis mount wirewound resistors are ideal for high-power applications due to their capability to handle significant amounts of heat generated during operation.

Why Buy Chassis Mount Resistors?

Investing in chassis mount resistors offers unparalleled reliability and durability across high-power applications. Their robust design and efficient heat dissipation capabilities make them ideal for demanding environments. By effective thermal management, these resistors ensure the reliability and longevity of electronic circuits, preventing damage to other components and ensuring consistent performance.   

Check Our Range of Chassis Mount Resistors

We offer a wide variety of chassis mount resistors to meet your specific needs. Our collection of chassis mount wirewound resistor types includes: 

  • Tubular Chassis Mount Resistors: These resistors have a cylindrical shape and are often used in high-voltage applications.
  • Enclosed Chassis Mount Resistors: They are enclosed in protective housing, making them ideal for harsh environments.
  • Metal Housed Chassis Mount Resistors: A metal-housed chassis mount resistor has a metal housing that provides excellent heat dissipation.
  • Aluminium Housed Chassis Mount Resistors: These resistors are similar to metal housed models, but they use an aluminium housing for even better heat dissipation.
  • Planar Chassis Mount Resistors: They feature a flat, rectangular shape and are designed for surface mounting.
  • Box Chassis Mount Resistors: They are enclosed in a box-shaped housing, which provides additional protection and mounting options.

Typical Uses of Chassis Mount Resistors

Chassis mount resistors are used in a wide variety of applications, including:

  • Power Supplies
  • Motor Control
  • Braking Systems
  • Welding Equipment
  • Industrial Machinery
  • Telecommunications
  • High-frequency Applications
