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. QUICK REFERENCE DATA Simple and effective overload protection can be provided by PARAMETER VALUE UNIT connecting a high-voltage PTC thermistor in series with the Maximum rated voltage 600 to 1000 V RMS instrument see Typical Connection of the PTC Thermistor Nominal holding current (Int) 10 mA for Digital Multimeter Protection drawing. Under normal conditions, the resistance of the PTC thermistor is low, so Resistance at 25 C (R ) 400 to 1600 25 the test voltage will be measured by the instrument. Under Tolerance on R value 20 to 30 % 25 an overload condition, the PTC thermistor will switch to its Maximum overload current I 0.5 to 2.0 A ol high-resistance state, absorbing the overload current and Switching temperature 90 to 115 C protecting the instrument. When the overload is removed, the PTC thermistor will return to its low-resistance state, Operating temperature range -20 to 85 C ready to resume its protective function. at rated voltage ELECTRICAL DATA AND ORDERING INFROMATION INT MAX.
