U.S. Sensor’s inrush current limiting power thermistors are specially formulated and
processed NTC thermistors suitable for suppressing high inrush currents in switching
power supplies and other applications where the high initial starting currents are
undesirable. Their unique design enables them to handle extremely high current and
voltage levels. In a typical power supply application, the device is used in series with the
filter capacitors. Upon application of the initial voltage, the device, due to its relatively
high resistance, limits the current flow to an acceptable level until the capacitors are
charged. Thereafter, the device decreases in resistance substantially to a level where the
voltage drop across it is negligible.
Maximum Steady State Current (Imax)
For power thermistors, the
maximum continuous steady
state current, either DC or RMS
AC, which the device is capable
of passing. The maximum
steady state current for U.S.
Sensor power thermistors is
determined assuming a
maximum operating ambient
temperature of 65°C. If a
specific application requires
ambient temperature operation
above 65°C, custom designed
devices are available.
Resistance At Maximum Current (RImax)
For power thermistors, the approximate resistance of the device under maximum steady
state current conditions.
