V 30V 100mW
metal oxide varistors
• material: zinc oxide (ZnΩ)
• operating temperature, max.: +85°C
• working surface temperature, max.: +115°C
• response time, max.: 25ns
• voltage/temperature coefficient: -0.05%/°C
• insulation resistance 500V: >1000MΩ
• used as voltage-dependent resistors (VDR's) to protect electronic devices
• they protect against overload build-up and protect valuable equipment from power surge damage
• surge voltages are absorbed in the varistor
selection criteria
• the maximum operating voltage must be lower than the varistor voltage.
