The Thermistor library is one of the component library types within the Component Library included in PI Expert. Once a thermistor is added to the library and included in a Component Set, you can manually choose your custom thermistor to be used where applicable. Thermistors are typically negative temperature co-efficient (NTC) devices. That means their resistance decreases as their temperature increases. These devices are used in series with the input of the power supply. They serve to reduce inrush current at startup when usually they are cold.
PI Expert does not allow you to modify or delete the default components. You can only view the parameters of a selected component type by clicking the View button. You can add custom components to the Component Library by clicking the Add button in the Component Library dialog where you can input all relevant specifications for a particular component. See the Component Library topic for more information on adding and editing components.
You can specify the following parameters to add a thermistor:
Resistance – Resistance of series element when it is cold
Rated current – Maximum rated current of thermistor
Part Number – Manufacturer part number
Manufacturer – Name of manufacturer
