Description:
 
The Cooper Bussmann family of PolyTron™ resettable PPTCs is ideally suitedfor protecting applications sensitive to high ambient operating temperatures orsubject to frequent overcurrent conditions.PPTCs operate as a positive temperature coefficient device. High temperatures and excessive current will cause the device resistance to increase until it limits the unsafe current level.Upon reaching the design temperature/current limit, the PPTC will effectively“open” the circuit to provide protection from the overcurrent or elevated ambient temperature condition.Once the fault is removed or the ambient temperature cools, the PPTC will automatically “reset” and conduct safe current levels again, allowing current to flow through the circuit.PPTCs are commonly used in applications where constant uptime is required and/or in circuits not easily accessible by a user or service technician.Available in surface mount and radial packages, Cooper Bussmann resettable PPTCs help improve the safety and reliability of customer equipment worldwide.
 
 
Applications:

 

Almost anywhere there is a load to be protected with a voltage supply of up to 90 V, including:
Broadband cable power passing taps
Set-top boxes
