Features and Benefits
PCB Wire Ended
Thermal fuses protect equipment against fire or thermal damage due to overload or overcharge. Suitable for use with standard single phase supplies up to 250V (230V typical). Temperature gradient: 1°C per minute.
Internal Resistance Test of A Series
* Test method: Measure the resistance between both lead wires at the distance of 10mm as shown in figure.
*Standard:Internal resistant should be less than 15 mΩ
* Test result:Normal
