Basic Characteristics of POSISTORr
Although there is a negligible difference between the
normal and "Curie-point" temperature, POSISTORr
shows almost constant resistance-temperature
characteristics. Yet they have resistance-temperature
characteristics that cause resistance to sharply increase
when the temperature exceeds the Curie-point.
This shows the relation between applied voltage when
voltage applied to POSISTORr causes balancing of
inner heating and outer thermal dissipation and stabilized
current. This has both a maximum point of current and
constant output power.
This shows the relation between current and time before
inner heating and outer thermal dissipation arrive at
equilibrium state. This features having large initial current
and abruptly continuous attenuating portion.
POSISTORr has three main characteristics.
