High-temperature resettable fuses

15 May 2013 Circuit & System Protection

Bourns has rolled out the new MF-PSHT series of Multifuse polymer PTC resettable fuses. This 0805 (2012 metric) size surface mount device is now Bourns’ smallest resettable fuse to use high-temperature PTC material.

Bourns’ high-temperature materials operate up to 125°C and have been primarily designed for automotive applications. However, with the trend to increase board density in other areas such as industrial, telecom and consumer electronics, the operating temperature of some electronics is increasing. This makes the miniature size PPTC with an elevated operating temperature ideal for high-density boards.

The MF-PSHT series uses Bourns’ new freeXpansion design which boasts higher hold currents, higher voltages, improved resistance stability and smaller footprints. The fuses are RoHS compliant.
