Product Description
Bourns MF-R110 Resettable Fuse is a compact radial leaded device engineered for protection of electrical and electronic circuits against overcurrent and short circuits. Rated at 30V and 1.1A holding current, it rapidly switches from a low resistance state to high resistance during fault conditions and automatically resets when power is restored, enabling maintenance-free operation.
Constructed with flame retardant epoxy polymer material that meets UL 94V-0 standards, the fuse is both safe and durable. It measures 8.9mm in length, 14mm in height, and 3mm in width, making it suitable for PCB wire-ended applications without requiring a fuse holder.
The MF-R110 fuse can handle a trip current of 2.2A and has a maximum resistance of 270mΩ. It has a power dissipation rating of 0.7W and operates reliably within a temperature range of -40°C to +85°C. The radial lead diameter is 0.51mm, allowing for stable soldering on circuit boards.
This series is UL, CSA, and TUV approved, ensuring compliance with international safety and quality standards such as RoHS and UL. Its quick automatic reset functionality provides effective circuit protection in applications such as security systems, power supplies and transformers, power switching devices, automotive and medical equipment, instrumentation, control systems, computers, telecommunications, and audio visual equipment.
This resettable fuse resets automatically thousands of times without replacement needed. The small size and radial leads enable space-saving PCB mounting. Designed for maintenance-free circuit protection against excessive electrical currents.
Suitable for use in industrial, laboratory, commercial, and consumer electronic environments. Complies with RoHS and UL safety standards for assured quality and reliability. Power dissipation and temperature ratings ensure stable operation under load.
Protects sensitive electronics by quickly switching states during faults and returning to normal automatically.
