1812L200MR Product Details

1812L200MR Overview


It is important to protect PTC thermistors from damage by placing them in 1812 packages. It is advisable to set the PTC thermistors to -40°C as the minimum operating temperature. A temperature of 85°C should not be exceeded during operation of this thermistor. 2 is the termination of the PTC thermistor. PTC thermistors could operate at 8V voltages. The PTC thermistors are designed for a 40A current. When using PTC thermistors, the current shouldn't exceed 40A.
