In PTC (positive temperature coefficient) thermistors, resistance increases as temperature increases.
WebThe inrush circuit limits any current flowing into the EMI capacitors, but does not introduce any additional EMI into the input lines, as is possible with a discrete circuitry. The VPTPCM-12 contains inrush limiting circuitry which will limit inrush current into its capacitors and those of downstream DC-DC converters.
