Thermal fuse incorporated cement resistors features
This resistors is constructed with thermal fuse which protect
circuit from overheat by over current, and prevent from a serious accident.
Thermal fuse have not almost calorific element,
but the element fusing in the case of heating resistor.
Once fused element never return, even if temperature down to normal.
(Reinforced anti-surge performance developed 2006/07)
- Excellent Anti-surge ability
- Long-term stability、Reliability
- Standards for safety approved by
UL File No.:E255350
CSA File No.: 229946
This resistors applications
Switching power source, Ac adapter
- Preventive inrush current for Power supply sircuit
- Protect circuit from the case of overload and overheat
