Bourns, Inc., a leading manufacturer and supplier of electronic components, today announced that the company has developed freeXpansion™, a new technology added to the company’s entire line of Multifuse® surface mount polymer positive temperature coefficient (PTC) resettable fuses.  This new technology increases the performance of the fuse with the ability to handle higher currents and voltages, improves its resistance stability and allows for a smaller footprint.  Due to its new freeXpansion™ technology, Bourns is able to introduce one of the smallest families of PTCs on the market with a size of 0603, designated the Bourns® MF-FSMF Series.  Bourns’ Multifuse surface mount devices manufactured using the freeXpansion™ process is designed to meet next-generation electronics smaller size and high current requirements.  Bourns® Multifuse® devices are an optimal overcurrent circuit protection solution for broad range of equipment including products with USB 2.0, USB 3.0 and HDMI ports and in consumer electronics and automotive electronics applications.

Polymer PTC resettable fuses expand when an overcurrent event occurs and contracts when they reset.  The freeXpansion™ technology allows the device to freely expand and contract without mechanical restrictions for more stable performance, extended product life and to be manufactured in a smaller size.

“Bourns® Multifuse® products with freeXpansion™ offer distinct competitive advantages for our customers enabling reliable circuit protection across a broader range of applications,” said Brian Ahearne, technical marketing manager for Bourns’® Multifuse® products.  “As more and more electronic products become portable with design space constraints, Bourns® Multifuse® devices match application requirements for a smaller package and the ability to handle higher currents and voltages helping our OEM customers protect their valuable circuits from overcurrent conditions.”

Bourns® Multifuse® devices act as critical circuit protection components by limiting dangerous current surges, such as short circuits in electrical equipment.  These devices provide secure protection as they react to an overcurrent event by changing from a very low resistive state to a very high resistive state.  This is also referred to as the positive temperature coefficient effect or PTC effect.  Once the overcurrent surge has passed, the Multifuse® device automatically resets to its low resistive state and allows the equipment to resume operation.
