Inrush current is the momentary surge of current created when power is turned on to motors, transformers, power supplies and heating elements. These current surges are usually less than one second in duration but are many times the magnitude of the normal operating current. The more power requir...

A PTC resistance value R(LV) can be taken from the "Resistance vs Temperature" graphs and multiplied by a corresponding ratio to estimate the (minimum) resistance value and determine a maximum peak current at a defined voltage. Example: a PTCEL17R501TBE type has a Rmin. (see Electrical ...

IOUT response curves between the constant and foldback current-limiting schemes. The reduction in output current (IOUT), as opposed to constant current-limiting, reduces power dissipation, thus reducing the thermal stress on the switching converter. Figure 3. VOUT vs. IOUT ...
A PTC resistance value R(LV) can be taken from the Resistance vs Temperature graphs and multiplied by a corresponding ratio to estimate the (minimum) resistance value and determine a maximum peak current at a defined voltage. Actual peak currents that could be reached at certain voltage levels ...
