Automotive Positive Thermal Coefficient (PTC) RL16 Series

 

PTC is the English abbreviation for positive temperature coefficient, a self-recovery fuse. When heated or when the current passing through it is too large, its resistance rises sharply to block the current, and then turns on again after its temperature drops.

Positive Thermal Coefficient Device (PTC), provides overcurrent protection for electrical and electronic devices. Their function is to use conductive metal strips embedded in the polymer. Under normal conditions, the resistance of the device is close to zero, but in the case of overcurrent, the PTC will be heated, causing the polymer to expand and increasing impedance. When the current returns to normal, the component will cool down and return to its original shape and very low resistance level.
