Bel Fuse Inc, a leading global manufacturer of products that power, protect, and connect electronic circuits, today announced the industry’s only surface mount, PPTC (polymeric positive temperature coefficient) resettable fuses, line-volt-rated to 240 VAC.
Designed to protect against electrical overloads and short circuits, Bel 0ZAF resettable fuses provide circuit protection for a variety of applications in the IoT, industrial, and medical sectors. These fuses are crucial for use in safeguarding industrial controls, test and measurement equipment, robotics, and safety systems, and deliver the reliability and durability required by these advanced technologies.
Their soldered surface mount design not only offers cost efficiency for PC mount assembly, but also accelerates design and production timelines by eliminating the need for through-hole mounting. Bel Fuse customers can take advantage of the new resettable fuses immediately, which are available from a variety of distributors.
Bel Fuse offers one of the broadest ranges of circuit protection products on the market today, and has been at the forefront of the industry shift to board level, surface mount, fuse designs, including the C2Q chip fuses with 0603 footprint.
For example, surface mount and PTC automotive fuses that are used to protect a circuit and its components from excessive current that could lead to vehicle damage are compliant with AEC-Q200 stress test qualification for passive electrical devices, confirming their high reliability, durability and stability, and ability to withstand high temperature, humidity and thermal shock.
Bel Fuse use a unique polymer formulation in their PTC resettable fuses to protect against harmful overcurrent and short circuit conditions. They are also used to protect against over temperature conditions not necessarily caused by excessive current. The PTC devices will reset after power to the circuit is removed, the fault is cleared and power is reapplied to the circuit. This ability to reset protects electronic equipment, which remains fully functional, and eliminates the need for service personnel to physically replace a fuse.
