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