!Note
!Basic Characteristics
1. Resistance - Temperature Characteristics
2. Current - Voltage Characteristics (Static Characteristic)
3. Current - Time Characteristics (Dynamic Characteristic)
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.
The Curie Point (C.P.) is defined as the temperature at
which the resistance value is twice the one at 25 C.
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.
• Please read rating and !CAUTION (for storage, operating, rating, soldering, mounting and handling) in this catalog to prevent smoking and/or burning, etc.
• This catalog has only typical specifications because there is no space for detailed specifications. Therefore, please review our product specifications or consult the approval sheet for product specifications before ordering.
