Bourns 0.9A 30V Resettable Fuse Radial Leaded Epoxy Polymer MF-R090-0-9

Bourns MF-R090-0-9 is a 0.9A rated resettable fuse designed for reliable overcurrent protection in a wide range of electrical and electronic circuits. It is rated for a maximum voltage of 30V and features a radial leaded design that facilitates easy PCB mounting.

The device provides a hold current of 0.9A and trips at 1.8A within approximately 5.9 seconds, effectively protecting sensitive components from damage. Constructed with a cured, flame retardant epoxy polymer, it is compliant with UL 94V-0 standards, ensuring safety and durability.

This resettable fuse rapidly transitions from a low resistance state to a high resistance state upon electrical overload or short circuit, automatically resetting itself to restore normal operation once the fault is cleared and power is removed. This functionality eliminates the need for fuse replacement, improving maintenance efficiency.

Its electrical and thermal specifications include a minimum resistance of 0.07Ω, maximum resistance of 220mΩ, power dissipation of 0.6W, and operating temperature range from -40°C to 85°C, making it suitable for demanding industrial and commercial applications.

The component holds certifications for RoHS compliance and UL approval, reflecting adherence to environmental and safety standards. The radial lead diameter measures 0.51mm. Automatically resets thousands of times to maintain circuit protection.

Precision hold and trip currents for accurate overcurrent response. Compact radial leaded construction suitable for PCB assembly. Flame retardant epoxy polymer housing rated UL 94V-0. Wide operating temperature range supports versatile applications.
