2920 Series PTC Resettable Fuse SMD

  • RoHS Compliant & Halogen Free
  • Faster tripping, 2920 Dimension, Surface mountable, Solid state
  • Maximum Voltage:6~60Vdc
  • Operating Current: 0.3A~3A,
  • Operating Temperature:-40℃ TO 85
Availability:
Quantity:

The resistance of PTCs rises as the temperature rises. With this feature, the value change of resistance is not obvious when the safe current passes, the resistance value changes drastically when abnormal current passes, this reaches the purpose of limiting abnormal current, the resistance value will “reset” automatically when the abnormality is eliminated and temperature returns to a safe level. It is an ideal choice for equipment with frequent abnormal over-current flowing area. PPTC often used in consumer electronics, power lines, telecommunications, I/O connectors, process control and medical equipment.
