MF-R135-2 Description

Short technical summary and product information.

The Bourns MF-R135-2 is a polymeric positive temperature coefficient (PTC) resettable fuse designed for overcurrent protection in electronic circuits. It is rated for a maximum voltage of 30V and a hold current of 1.35A, with a trip current of 2.70A. The device can handle a maximum fault current of 40A, making it suitable for a variety of power and signal line applications.

 

Key electrical specifications include an initial resistance range of 0.065Ω to 0.115Ω, a post-trip resistance of 0.170Ω maximum, and a maximum time to trip of 7.3 seconds at 23°C. Typical tripped power dissipation is 0.80W. The operating temperature range is -40°C to 85°C.

 

The MF-R135-2 is housed in a radial, disc package with a diameter of 8.90mm and thickness of 3.00mm. It features a lead spacing of 5.10mm and an overall height of 18.90mm, designed for through-hole mounting on printed circuit boards. The component is RoHS3 compliant, lead-free, and halogen-free, with a California Prop 65 warning for cancer and reproductive harm.
