OUR Products
The company has established production bases in Shandong and Guangdong, where it conducts research and development and production of current and temperature protection devices.
Features
1. Rapid operation to protect the circuit in an overcurrent condition abnormality such as a short circuit.
By removing the overcurrent condition, these products automatically return to the initial condition and can be used repeatedly.
2. Suitable for countermeasure to short circuit test in safety standard.
3. Stable resistance after operation due to ceramic PTC.
4. Similar size is possible due to the large capacity for electric power.
5. Possible to use these products as current limiting resistors with ercurrent protection functions
6. The SMD type's small size and light weight are helpful in miniaturizing the circuit.
