For power supply
Inrush Current Limit for Power Supply
wattage power
POSISTORr is an integrated solution to work as both
current limit resistor and overcurrent fuse. It works as a
stable resistor in normal operation and protects itself
against overcurrent situations.
(1) High wattage power supply (flat display panels etc.)
(2) Power supply for fluorescent lights
(3) Other switching power supplies
(1) Protection against overcurrent situations
(2) Automatic reset from protective trip mode
(3) Space-saving
(4) Various characteristics to meet a suitable resistance
Choose an appropriate part number based on the
resistance value required to the inrush current limit.
Review the maximum voltage.
