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. The compact MF-NSHT and MF-USHT Series use Bourns’ freeXpansion™ design that increases the
performance of the resettable fuse.
