Basic Characteristics of POSISTOR

1. Resistance - Temperature Characteristics

Although there is a negligible difference between thenormal and "Curie Point" temperature, POSISTORrshows almost constant resistance-temperaturecharacteristics. Yet they have resistance-temperaturecharacteristics that cause resistance to sharply increasewhen the temperature exceeds the Curie Point.The Curie Point (C.P.) is defined as temperature whichthe resistance value is twice the one at 25 °C.

2. Current - Voltage Characteristics (Static Characteristic)This shows the relation between applied voltage whenvoltage applied to POSISTORr causes balancing ofinner heating and outer thermal dissipation and stabilizedcurrent. This has both a maximum point of current andconstant output power.

3. Current - Time Characteristics (Dynamic Characteristic)This shows the relation between current and time beforeinner heating and outer thermal dissipation arrive atequilibrium state. This features having large initial currentand abruptly continuous attenuating portion.
