Bourns 0.2 A Resettable Fuse 30V Surface Mount Technology MF-MSMF020-2

Bourns MF-MSMF020-2 is a resettable fuse with a 0.2 A hold current designed for protecting electrical and electronic equipment against excessive current and short circuits, rated for a voltage of 30 volts. It employs surface mount technology to facilitate automated assembly and is packaged in an 1812 size reel format. The device switches rapidly from low resistance to high resistance under fault conditions, automatically resetting when power is removed and faults clear.

This fuse features electroless nickel immersion gold plated terminals for optimal conductivity and corrosion resistance. It operates reliably within a wide temperature range from -40°C up to a maximum of 85°C, making it suitable for harsh and automotive environments.

With a quick trip time of 0.1 seconds and a trip current rating of 0.4 A, it provides fast circuit protection. The maximum resistance can reach up to 6 ohms while the minimum resistance is 0.4 ohms. Power dissipation is rated at 0.8 watts, ensuring safe handling of overloads.

The MF-MSMF series is designed to be fully compatible electrically with previous generations of 1812 SMT devices and supports both leaded and lead-free solder profiles. It holds compliance certifications including UL and RoHS. Applications include security systems, power supplies, transformers, automotive and medical equipment, instrumentation and control systems, computers, peripherals, and telecom devices.

This resettable fuse automatically resets after an overcurrent event without needing replacement. Compact 1812 SMT package fits modern PCBs with limited space. Robust terminal plating enhances durability and solderability.

Wide operating temperature range supports diverse industrial and automotive environments. Electrical parameters comply with stringent automotive AEC-Q200 Rev-C stress qualifications. Maintenance-free operation provides thousands of automatic reset cycles.

Helps protect circuits in a variety of industrial, automotive, medical, and consumer electronic devices. Compliant with environmental and safety standards including RoHS and UL. Packaged in reels for efficient manufacturing and handling.
