PTCCL - 600 V / 1000 V Series www.vishay.com Vishay BCcomponents 600 V / 1000 V PTC Thermistors for Overload Protection FEATURES • • • • • Fast response time for rapid protection Automatic resetting once overload is removed Operates on DC or AC voltage UL approved types available (E148885) Material categorization: for definitions of compliance please see www.vishay.com/doc?99912 APPLICATIONS Over-temperature/over-load protection for metering, low current signal protection, digital signal protection against over-voltage DESCRIPTION Test and measuring instruments, such as oscilloscopes and digital multimeters, can be easily damaged if excessive voltages are applied across their input terminals. Simple and effective overload protection can be provided by connecting a high-voltage PTC thermistor in series with the instrument; see Typical Connection of the PTC Thermistor for Digital Multimeter Protection drawing. Under normal conditions, the resistance of the PTC thermistor is low, so the test voltage will be measured by the instrument. Under an overload condition, the PTC thermistor will switch to its high-resistance state, absorbing the overload current and protecting the instrument. When the overload is removed, the PTC thermistor will return to its low-resistance state, ready to resume its protective function.
