SEREB® SB Type Thermal Protector

Product Description

SEREB® is a thermal protector integrated into the battery cells of various portable electronic devices. It interrupts the current flow in the event of overheating or when over-current causes self-generation of abnormal heat levels. In these situations, the rise in temperature will cause the bimetal element within the protector to reverse, shunting the conductive line to the PTC ceramic. The bimetal element remains reversed until there is a sufficient voltage drop.


SEREB® offers the following advantages:
  • Various operating temperatures ( 72℃, 77℃, 82℃, 85℃)
  • Low-profile and light-weight construction with a maximum height of only 1.05 mm
  • High sensitivity due to slim body design
  • In accordance with RoHS and REACH guidelines, and Halogen-free


SEREB® is mainly used to protect the battery cells of portable electronic devices such as notebook and tablet computers.
