MF-RG PPTC Resettable Fuses

Bourns' Multifuse® product line announces the introduction of a series of new part numbers to the MF-RG product family of radial through-hole polymer positive temperature coefficient (PPTC) resettable fuses. The MF-RG product family offers circuit protection solutions for applications in the automotive, data server, and industrial electronics industries. The additional eight new models will now extend the maximum operating current of the MF-RG series from 3 A to 11 A.

The MF-RG products are rated to a maximum operating voltage (V_RMS) of 16 V and exhibit a high current carrying capability. The key feature of the MF-RG family is the reduced size of the products compared to the existing through-hole products (MF-R, MF-RX) in the Multifuse polymer PTC product portfolio. The smaller size offers a space-saving advantage. In addition, the smaller size reduces the thermal mass of the products, resulting in a faster circuit protection solution.

A second feature is the product family's tighter hold-to-trip ratio. This enables design engineers to use a device that operates much closer to the fault current of the application, thereby further enhancing the speed of response to an overcurrent event.

The MF-RG Multifuse PPTC products are produced in Bourns' TS16949 approved facility in Xiamen, China. They are RoHS compliant, UL recognized for safety requirements, and meet AEC-Q200 compliance standards for passive components.

Applications

• Automotive applications
• Anywhere space is limited and fast tripping is required
