Bourns is pleased to announce the introduction of the new 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. The compact MF-NSHT and MF-USHT Series use Bourns’ freeXpansion™ design that increases the performance of the resettable fuse with: Higher hold currents (Ihold), Improved resistance stability, Higher voltages (Vmax) and Smaller footprints.
The new MF-NSHT and MF-USHT series are RoHS compliant*, AEC-Q200 certified for safety requirements
and are produced in Bourns’ TS16949 approved facility in Xiamen, China.
* RoHS Directive 2002/95/EC Jan. 27, 2003 including annex and RoHS Recast 2011/65/EU June 8, 2011.
