Ohmite ARC3 Non inductive, thick film Datasheet

ARC3 High Voltage Precision Resistors
Designed for applications such as voltage dividers,
medical and measuring equipment, electrostatic and
current limiting devices where high stability, low TCR
and high ohmic values are required.
• Non Inductive, Thick Film
• High Voltage to 96 kVdc
• Low TCR
• Tolerance as low as ± 0.1%
• RoHS Compliant
