Expanded PPTC line with smaller size models offering extended operating current

Bourns has announced the expansion of its successful MF-RG Series Multifuse polymer positive temperature coefficient (PPTC) resettable fuse product line. The eight new MF-RG Series models extend the maximum operating current of the series from 3A to 11A, and are a smaller size compared to Bourns' existing through-hole Multifuse products (MF-R, MF-RX), thus delivering a space saving and thermal advantage resulting in a higher performing circuit protection solution.   These radial through-hole products are rated to a maximum operating voltage (Vrms) of 16V offering high current-carrying capability. The new models feature a tighter hold to trip ratio that operates much closer to the fault current of the application, thereby delivering a faster response solution for overcurrent events. The smaller size with a similar hold rating and fast tripping capabilities make the company’s latest devices excellent circuit protection solutions for a broad variety of automotive, industrial and communications market applications.
