PTC Thermistor/over current110 C

PTC Over Current Protectors are used in series to protect electronic circuits when an over current condition develops. When a fault develops in a circuit leading to an over current condition, The PTC Thermistor switches from its low resistance state to a very high resistance state (this can be several decades of change) reducing the current flow to a very low and safe level.

Definitions

Maximum Continuous Current (Imcc)
The maximum amount of current which a PTC Thermistor must be able to pass without switching into its high resistance state. Expressed in Amps.

Minimum Switching Current (Imsc)
The Minimum amount of current necessary to switch the thermistor into its high resistance state. Expressed in Amps.
