What is an automotive PTC device? Automotive PTC devices are specifically designed to protect electronic equipment in automotive applications. The key difference between automotive PTC devices and other PTC devices is the rigorous qualification process required to test the parts in an automotive environment. The PTC automotive device is available in surface mount, radial leaded and blade type configurations. The automotive PTC device is qualified under the PS400 specification which is derived from AEC-200, the standard for electronic components in the auto industry.

Key parameters for the PTC automotive device offerings are as follows:

PTC Series	Style	Hold Current	Max Voltage	Max Fault Current
nanoASMDC	SMT	0.12 to 0.35A	48 to16V	10 to 100A
microASMD	SMT	0.05 to 0.10A	30V	10A
miniASMDC	SMT	0.10 to 2.60A	60 to 16V	10 to100A
AHS	SMT	0.8 to 3.0A	16V	70 to 50A
