Bourns adds high-temperature PPTC resettable fuses to its Multifuse line

Bourns, a leader in electronic components, announced it has added new AEC-Q200 certified high-temperature Polymer Positive Temperature Coefficient (PPTC) resettable fuses to its line of Multifuse products.

Provided in 1206 and 1210 (3014 and 3024 metric) surface mount packages and featuring operating temperatures up to 125 °C, Bourns designed the miniature sized MF-NSHT and MF-USHT series as ideal circuit protection solutions for automotive systems, and to provide superior resettable fault protection for a new generation of high density boards in industrial, telecom and consumer electronics that also must operate in elevated temperatures.

The latest high-temperature Multifuse models are based on Bourns’ freeXpansion technology, which is a space-saving manufacturing process that enables smaller surface mount package sizes and increased fuse performance with higher hold currents (Ihold), improved resistance stability and higher voltages (Vmax). The MF-NSHT and MF-USHT series provide higher hold currents at elevated temperatures with Ihold up to 0.50 Amps and post trip resistance as low as 1.6 Ohms.

“Many automotive systems, particularly in under-the-hood applications, must operate in extremely harsh environmental conditions. Bourns’ experience in high-temperature surface mount PPTC resettable fuses helps ensure reliable operation while also enabling designs to meet AEC-Q200 Rev-C stress test qualifications,” said Lee Bourns, Multifuse Product Line Manager. “Our latest MF-NSHT and MF-USHT series give automotive and electronics designers new overcurrent protection options in addition to Bourns’ already popular high-temperature MF-PSHT, MF-SMHT, and MF-RHT products.”

Manufactured in a Bourns TS16949-approved facility, the Multifuse Model MF-NSHT and MF-USHT series are available now, are RoHS compliant* and UL recognized for safety requirements.
