Bourns 1.1 A 6V Resettable Fuse Surface Mount Technology 1206 Footprint MF-NSMF110-2

Bourns MF-NSMF110-2 resettable fuse is a high-performance, compact 1.1 ampere fuse rated at 6 volts, designed using Surface Mount Technology in a standardized 1206 footprint. It provides automatic protection to electrical and electronic circuits by quickly switching to a high resistance state under electrical overload or short circuit conditions, and resets once the fault is cleared and power is removed.

Its symmetrical low-profile design and electroless nickel immersion gold plated terminals ensure excellent electrical connection and stability on circuit boards. The fuse's small dimensions (3.4 mm length, 1.8 mm width, and 0.7 mm height) enable efficient space-saving on densely populated printed circuit boards.

This resettable fuse boasts a rapid trip time of 0.1 seconds at a trip current of 2.2 A, providing swift reaction to fault events, thus protecting sensitive components and improving system reliability. It supports a hold current of 1.1 A and power dissipation of 0.6 W, with minimum resistance at 0.06 Ω and maximum at 200 mΩ.

The device operates reliably in ambient temperatures ranging from -40°C to 85°C and is compliant with UL and RoHS standards, making it suitable for commercial and industrial applications. Its maintenance-free automatic reset feature endows it with thousands of repeat cycles, lowering maintenance efforts and downtime.

Typical usage scenarios include applications in security systems, power supplies and transformers, power switching devices, automotive and medical equipment, instrumentation and control systems, computers and peripherals, as well as audiovisual and telecommunications devices. These varied applications highlight its versatility and robustness in circuit protection roles.

This Resettable Fuse provides protection for electrical and electronic circuits against excessive currents. Features a fast time to trip of 0.1 seconds to react quickly to fault conditions. Equipped with electroless nickel immersion gold plated terminals for reliable electronic connections.
