Bourns MF-FSHT series high temperature PPTC resettable fuses

The Bourns model MF-FSHT series High Temperature Surface Mount Polymer Positive Temperature Coefficient (PPTC) Resettable Fuses. The new series provides Ihold current ratings from 0.05A to 0.16A at the 12V maximum rated voltage and a maximum operating temperature up to +125°C. 

The addition of the new Model MF-FSHT series provides a broader standard high temperature PPTC offering to customers with high working temperature requirements, particularly in industrial and other demanding applications. The new Bourns^® Model MF-FSHT series utilises Bourns’ innovative freeXpansion™ design that increases the performance of the resettable fuse with: 

• Higher hold current ratings (Ihold) 
• Improved resistance stability 
• Higher maximum voltage ratings (Vmax) 
• Smaller footprints

Features

• Operating temperature range up to 125°C
• Higher hold currents at elevated temperatures
• Low thermal derating factor
• Small 0603 footprint size with low profile forspace-constrained applications
• Surface mount packaging for automated assembly
• RoHS compliant*
• cUL and TÜV recognised

Applications​

• Overcurrent surge protection of electronic equipment required to operate at elevated temperatures
• Resettable fault protection for industrial and consumer electronic equipment
