Bourns 1.35 A Resettable Fuse 30V Radial Leaded, Automatic Reset Protection MF-R135

Bourns MF-R135 Resettable Fuse is a high-reliability electronic protection device rated at 1.35 A hold current and 30V maximum voltage. It is a radial leaded resettable fuse constructed using a cured, flame retardant epoxy polymer insulating material that meets UL 94V-0 standards, providing enhanced safety and durability.

This fuse rapidly switches from a low resistance state to a high resistance state under overcurrent conditions, such as electrical overload or short circuit, safeguarding electronic and electrical circuits effectively. It automatically resets itself thousands of times, eliminating the need for fuse replacement and maintenance, thus reducing downtime and improving operational efficiency.

The MF-R135 features a trip current of 2.7 A with a time to trip approximately 7.3 seconds. Its compact physical dimensions of 8.9 mm length, 18.9 mm height, and 3 mm width make it suitable for space-constrained PCB installations. The fuse supports operational temperatures ranging from -40°C to 85°C, ensuring reliable function in a wide range of industrial and commercial applications.

Lead diameter of 0.51 mm and radial lead orientation facilitate straightforward PCB mounting. The fuse rating includes a maximum resistance of 170 mΩ and minimum resistance of 0.065 Ω, maintaining circuit integrity during normal operation and rapid transition to protection mode during faults.

This device complies with UL and RoHS standards, supporting environmental and safety compliance requirements in industrial automation, electronics manufacturing, instrumentation, telecommunications, medical devices, and power supply systems.

Common applications include security systems, power supplies and transformers, power switching devices, automotive and medical equipment, instrumentation and control systems, computers and peripheral devices, and audio visual equipment.
