Bourns Multifuse family of Polymer Positive  
Temperature Coefficient (PPTC) “resettable  
fuses” are used in a wide variety of circuit  
protection applications.  
Applications  
• Computer  
• Battery  
• Automotive  
• Telecommunications  
• Industrial  
Under fault conditions the device resistance  
will rise exponentially and remain in a  
• Consumer  
“tripped” state, providing continuous circuit  
protection until the fault is removed. Once the  
fault is removed and the power cycled the device  
will return to its normal low resistance state.  
What’s New in this Edition  
• Telecom Rated Products  
• MF-R/90  
• MF-R/250  
• MF-R/600  
Features/Benefits  
• Resettable circuit protection
