Ultra-low resistance PPTC resettable fuses for space-constrained portable applications

Bourns has expanded its successful line of ultra-low resistance Multifuse PPTC resettable fuses. The company is introducing the new model series MF-PSML (0805 size) while adding new low-profile devices to the company's existing MF-NSML (1206 size) and MF-USML (1210 size) series products. It is extensively increasing its Multifuse product line to provide design engineers with a breadth of low-resistance overcurrent and thermal circuit protection solutions that meet their space-constrained application requirements. All the new models are based on their 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 ultra-low resistance, small footprint, and low profile all make our latest Multifuse product series ideal protection solutions for a new generation of space-constrained portable devices including smartphones, tablets, wireless headphones, PC motherboards, USB drives and gaming consoles," said Lee Bourns, Multifuse product line manager at Bourns, Inc. "And because these devices are based on Bourns' freeXpansion technology, they offer superior current, voltage and resistance performance over traditional PTC solutions for designs that require more advanced overcurrent and overtemperature protection.”
