POWER SOLUTION - NIKKOHM
Precision High Voltage Non-Inductive Resistors
HVR
Features and Applications
Designed to high voltage applications as 4kV to 30KV.
Wide range of resistance to more than 10Gohm at 1%-10% are available.
Non-inductive structure and excellent long-term stability are realized with thick film technologies
and epoxy or silicone coating.
High voltage power supplies on industrial apparatus, such as physical &chemical measurement
equipment, X ray equipment, and an electron microscope. laser equipments, and miscellaneous
scientific equipment.
