POSISTOR r for Circuit Protection
Inrush Current Suppression for High Capacitance (100μF or more)
R90E.pdf
Mar.4,2014
POSISTOR r is one of lead type PTC Thermistor that is able
to support overcurrent or inrush current issue on the power
supply circuit.
It is able to integrated circuit for protection from inrush
current suppression with POSISTOR r and relay or
semiconductor switch as thyristor.

4. Various characteristics to meet a suitable resistance
value
c Applications
POSISTOR r is an integrated solution to work as both
current limit resistor and overcurrent fuse. It works as a
stable resistor in normal operation and products itself
against overcurrent situation.
It can be replaced from normal resistor or the resistor with
temperature fuses solution as Fig.1.

Max. inrush current shows the maximum applying time of inrush current value at operating temperature range.
Max charge energy is de?ned as the maximum charged up energy value of over 95%.
The capacitance is calculated as the following formula.
J=CV^2/2 C: capacitance, V: peak voltage
Note: The criteria of the standard for the maximum charged up energy value of over 95%.
If there is the difference between our de?nition and yours, could you ask us free?
Operating temperature range is -20 to +85°C.
