Bourns offers the model MF-NSHT and MF-USHT series high temperature Multifuse polymer PTC resettable fuses. These 1206 and 1210 (3014 and 3024 metric) sized surface-mount devices join Bourns’ already successful MF-PSHT high temperature SMD series.

Bourns’ 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.

Applications

• Protection of automotive circuitry including engine control modules
• Overcurrent surge protection of electronic equipment required to operate at high operating temperature ranges
• Resettable fault protection for general electronic equipment
