Patented freeXpansion PTC Resettable Fuse | Bourns

Bourns® freeXpansion™ PTC Resettable Fuse designs allow the polymer material to freely expand and contract during temperature changes. This reduces the internal stresses on the material, resulting in improved performance manifested in three areas: a greatly reduced aging characteristic due to repeated operations, improved reliability and higher withstand voltages.
