ARF Low Profile Wirewound
Metal Clad Resistors
Flexible design with high pulse capability, ideally suited to
braking and inverter / converter applications. Enhanced power
levels can be achieved when heatsink mounted.
⢠High power density
⢠Low profile
⢠600V cables as standard
⢠Heatsink mount for increased power dissipation
⢠RoHS Compliant
