ZR series (Low voltage general purpose type)
The general-purpose disc type ZR series is best suited as an element to protect electronic equipment, control equipment, and general electronic devices from a surge and a noise as a varistor for low pressure.
- features
- This varistor is excellent in voltage nonlinearity and can suppress the clamping voltage at a low level.
- The voltage-current characteristic of this varistor is symmetrical, and accordingly, this varistor can handle a surge with both positive and negative polarities and can be used for an AC circuit.
- This varistor is compact but has high surge resistance, and accordingly this varistor is stable for repeated surges.
- This varistor responds quicker and less follow current in comparison with a discharging protection element.
- Small temperature coefficient
- Wide serviceable voltage range
- High reliability
- Applications
- Protection from instantaneous overvoltage of various semiconductors
- Protection from an inductive lightning surge caused by wiring and communication lines
- Protection from a switching surge caused by relays or the like
- For stabilizing voltage
