Description Specifications

The ESP series high pulse absorption resistors are designed for applications requiring the dissipation of large pulse energy within a short time. They are particularly suitable for circuits that need to absorb significant pulse energy, such as random strong pulse energy discharge resistors and variable frequency motor braking resistors. These resistors operate effectively without forced air cooling (though better performance can be achieved with fans).

Technical Features

  • RC Circuit Testing : The resistors utilize an RC circuit to test pulse load capacity. Specific parameters are listed in the table below.
  • Special Design : The resistors feature a unique cylindrical ceramic body structure with a thick-film resistor coating on 96% high-quality ceramic material. Both ends are plated with copper terminals, serving as electrical leads and providing mechanical support.
  • Pulse Load Capability : The resistors have excellent pulse load handling capability.

The  high pulse absorption resistors offer robust performance in applications requiring rapid energy dissipation. Their unique design, coupled with precise specifications, makes them versatile for various industrial and electronic systems. Whether used in braking circuits or other high-energy scenarios, these resistors provide reliable and efficient solutions.
