0805 Series Resettable Fuses

  • RoHS Compliant & Halogen Free
  • Faster tripping, 0805 Dimension, Surface mountable, Solid state
  • Maximum Voltage:6~15Vdc
  • Operating Current: 0.05A~1.10A,
  • 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.


Specifications

● Certification: RoHS

● Packaging: in reel

● Smaller size saves board space and cost

● Resettable circuit protection

● Fast time-to-trip

● Low resistance

● Surface mount packaging for automated assembly

● Lead-free and compliant with the European Union RoHS Directive 2002/95/EC


Test Procedures and Requirements

Test Test Conditions Accept/Reject Criteria
Resistance In still air @ 25℃ Rmin≤R≤R1max
Time to Trip Vmax, 25℃, In still air @ 25℃ T≤max. time to trip(seconds)
Hold Current 30 min. at IH, In still air @ 25℃ No trip

Warning

PPTC devices are intended for protection against occasional over-current or over-temperature fault conditions ,and should not be used when repeated fault conditions are anticipated . Operation beyond maximum ratings or improper use may result in device damage and possible electrical arcing and flame.
