Circuit Protection Devices

Bourns manufactures and supplies a wide range of circuit protection technologies, including fuses, PTC thermistors, varistors, GDTs, resettable thermal cut-offs, surge protection devices, hybrid protectors, discrete semiconductor solutions, and more. Reliable surge protection is a critical design consideration to help ensure operational reliability of consumer electronics, industrial/communication equipment, automotive, battery charging, energy storage infrastructure, and renewable energy harvesting ecosystems.

MF-MSMF Multifuse® PTC Resettable Fuses

Bourns MF-MSMF Multifuse^® PTC Resettable Fuses are 100% electrically compatible with all previous generations of 1812 SMT devices and feature surface-mount packaging for automated assembly. These fuses are AEC-Q200 compliant with Pb and Pb-free solder reflow profiles. Bourns MF-MSMF fuses offer overcurrent and overtemperature protection of automotive electronics and are ideal for hard disk drives, PC motherboards and peripherals, point-of-sale (POS) equipment, PCMCIA cards, USB port protection, and HDMI 1.4 source protection.

Resettable Multifuse® Devices

Biurns Resettable Multifuse® devices shield a wide range of applications against overcurrent conditions. A variety of speed, voltage, and current limits are available.

Multifuse® PTC Resettable Fuses

Bourns Multifuse® PTC Resettable Fuses are available in polymer or ceramic with surface-mount, through-hole, or strap-mount configurations. The materials used in these fuses allow them to reset after a fault condition has been removed, and the increase in resistance changes exponentially rather than in a linear manner. Resettable overcurrent protection offers reliability and a longer part life. Bourns Multifuse PTCs provide resettable overcurrent protection, extra-low resistance, and are RoHS compliant. These fuses are ideal circuit protection for a variety of industrial and consumer applications, including computer, battery, automotive, and telecommunications.
