High-temperature resettable fuses

19 July 2017 Circuit & System Protection

Bourns announced the introduction of the new MF-NSHT and MF-USHT high-temperature ‘Multifuse’ polymer PTC resettable fuses. These 1206 and 1210 (3014 and 3024 metric) sized surface mount devices join the company’s MF-PSHT high-temperature SMD series.

The high-temperature materials used in this product family operate up to 125°C and have been primarily designed for automotive applications. However, with the ongoing 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 fuses use Bourns’ freeXpansion design that increases the performance by offering higher hold currents, improved resistance stability and higher voltages in smaller footprints. They are RoHS compliant and AEC-Q200 certified for safety requirements.
