Bourns MF-MSHT series high temperature PPTC resettable fuses

The Bourns model MF-MSHT series offers high temperature surface mount Polymer Positive Temperature Coefficient (PPTC) resettable fuses. The series provides Ihold current ratings from 0.20 A to 1.75 A at the 9 V ~ 42 V maximum rated voltage and a maximum operating temperature up to +125 °C. The addition of the model MF-MSHT series provides a broader standard high temperature PPTC offering to customers with high working temperature and power rating requirements. The Bourns® model MF-MSHT series utilizes 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
• Standard 1812 footprint size with low profile for space-constrained applications
• RoHS compliant*
• cUL and TÜV recognized
• Automotive grade

Applications​

• Overcurrent surge protection of electronic equipment required to operate at high operating temperature ranges
• Robust resettable fault protection for industrial transportation, communication, security and consumer electronic equipment
