BOURNS High Temperature Resettable Fuse MF-MSHT
Achieving a maximum operating temperature of +125°C, exceeding the conventional PTC product limit of +85°C, with eight types of holding current values ranging from 0.20A to 1.75A.
The MF-MSHT series expands the operating temperature range to -40°C to +125°C and consists of eight types with rated voltages from 9V to 42V and hold current values from 0.20A to 1.75A. In addition to existing resettable fuses, this is a proposal for a wider range of standard high-temperature PPTC products. This new MF-MSHT series utilizes the innovative patented technology freeXpansion design to enhance the functionality of resettable fuses as follows: • Higher hold current rating (Ihold) • Improved resistance stability • Higher maximum voltage rating (Vmax) • Smaller footprint
