This develops a breadth of low-resistance overcurrent and thermal circuit protection solutions that meet space-constrained application requirements.
With package sizes from 1210 to 0805, the expanded Multifuse line delivers increased resettable fuse performance from higher hold currents (Ihold) up to 7.0A higher voltages (Vmax) and post trip resistance values as low as 12 mOhms for enhanced resistance stability. For example, providing ultra-low resistance values helps boost the line’s current-carrying capability where one model can now achieve a 7A Ihold in a compact 1210 package (MF-USML700-2). These features enable longer battery life and faster charging in today’s smaller lithium-ion battery-based devices making the new models suitable as resettable protection solutions for a wide range of portable electronic applications.
All these Multifuse models are based on Bourns’ freeXpansion technology, which is a space-saving manufacturing process that enables smaller surface mount package sizes, while also making it possible for Multifuse devices to handle larger currents and voltages with improved resistance stability.
The latest Multifuse PPTC resettable fuses are UL recognized for safety requirements.
