The 60R Series Resettable devices utilize a unique polymer-based, Positive Temperature Coefficient (PTC) material to protect electrical circuits against overcurrent conditions.
The Littelfuse 60R Series consists of radial leaded resettable Positive Temperature Coefficient (PTC) devices designed to protect electrical circuits against overcurrent conditions. These components utilize a unique polymer-based material that increases resistance significantly when exposed to excessive current, thereby limiting flow until the fault is removed and the device cools down.
| Maximum Surface Temperature | 125°C |
|---|---|
| Operating/Storage Temperature Range | -40°C to 85°C |
| Voltage Rating | 60V |
| Short Circuit Rating | 40A |
| Passive Aging Test Condition | 85°C, 1000 Hours |
It protects electrical circuits against overcurrent conditions by limiting current flow when the polymer material temperature rises.
Once the cause of the initial overcurrent condition is eliminated, the device cools down and resets to a low resistance value.
The devices are recognized by Underwriters Laboratory (UL), CSA, and approved by TUV.
