ACS
Axial Coated Silicon Resistors
The design of the ACS resistor provides a good
balance of power density, stability and resistance to
environment for a broad range of industrial power
applications, such as drives and controls.
•
Good ratio between power capability and physical size
•
Wound to maximise high pulse capability
•
Low inductive versions available
•
Available on tape and reel or bulk
•
RoHS Compliant
