Polymer PTC Thermistors

The PPTCs are known under the trade names PolySwitch or Multifuse. Here PPTC stands for the English name Polymer Positive Temperature Coefficient. PPTCs are the perfect solution for the demanding circuit protection.

If the maximum allowed power is exceeded, the PPTC and a high impedance, whereby the flow is throttled under the normal current heats. After cooling the polymer PTC, it falls back into its original state. Their properties polymer PTCs are an inexpensive solution for short circuit protection and overload protection.
