CHARACTERISTICS OF FUSIBLE RESISTORS
Fusible resistors are capable of acting as both a regular resistor and as a fuse when abnormal current comes in. Since the two
functions are performed by only one component the cost is lower.
The Z302 BV 20327 fuses when overloaded at more than 100 times the rated power. In line-powered devices, these fusible
resistors can be used to act as a fuse when malfunction occurs and line voltage drops across the resistor.
To prevent flames or explosion when fusing, the device has an inflammable construction with high dielectric strength. After fusing
the resistance value will be more than 100 kΩ to realize sufficient circuit break. The components are mainly designed specifically
to customer requirements.
APPLICATIONS FOR FUSIBLE RESISTORS
•
Power supplies
•
Energy saving lamps
•
Battery charges
