IH=Hold current-maximum current at which the device will not trip at 23℃ still air.

IT=Trip current-minimum current at which the device will always trip at 23℃ still air.

V MAX=Maximum voltage device can withstand without damage at its rated current.

I MAX= Maximum fault current device can withstand without damage at rated voltage (V MAX).

Pd=Maximum power dissipated from device when in tripped state in 23℃ still air environment.

RMIN=Minimum device resistance at 23℃.

RMAX=Maximum device resistance at 23℃

R1MAX=Maximum device resistance at 23℃, 1 hour after tripping.

Physical specifications:

Lead material: 0.10 mm nominal thickness, quarter-hard nickel.

Insulating material: Polyester tape.

Warning:
  1. Operation beyond the specified maximum ratings or improper use may result in damage and possible electrical arcing and/or flame.
  2. PPTC device are intended for occasional overcurrent protection. Application for repeated overcurrent condition and/or prolonged trip are not anticipated.
  3. Avoid contact of PPTC device with chemical solvent. Prolonged contact will damage the device performance.

All the specifications are subject to change without previous notice.
