Mini-Mox Series

Mini-Mox
Precision Thick Film Axial Terminal
High Voltage/High Resistance
F e at u r e s
A p p l i c at i o n s
•Wide resistance ranges
•Silicone or epoxy coating
•Metal oxide resistive element
•Avionics
•Medical electronics
•High gain feedback applications
•Current pulse limiters
•Vacuum and space application
The Mini-Mox resistor is very versatile, covering a wide resistance
range as well as a wide range of
operating voltages. Provided with
tolerances down to 0.5%, the MiniMox resistor works well in precision
circuits.
