Product Description
Littelfuse MICROSMD150F is a 1.5 A resettable fuse operating at 6V dc, designed specifically for electrical and electronic circuit protection. This fuse rapidly switches from a low resistance to a high resistance state during electrical overload or short circuit conditions, automatically resetting once the fault is cleared and power is removed.
This micro SMD series fuse utilizes surface mount technology with an SMT footprint of 3225 metric (1210 imperial), facilitating compact integration onto printed circuit boards without the need for fuse holders.
Key attributes include a trip current of 3A, current rating of 40A, and hold current of 1.5A. The device features a matt tin terminal material providing robust connectivity and resistance stability.
It is rated for a power dissipation of 0.8W and maintains performance within a temperature operating range between -40°C and 85°C, suited for demanding industrial and commercial environments.
Approved under TUV, CSA, RoHS, and UL standards, this resettable fuse suits applications including security systems, power supplies, transformers, automotive and medical equipment, instrumentation, control systems, computers, peripherals, audiovisual, and telecommunications equipment.
Automatically resets for thousands of cycles ensuring long lifecycle and maintenance-free operation. Compact size allows efficient use of PCB real estate with no fuseholder needed. Designed for rapid response to prevent damage from current overloads or short circuits.
Comprehensive industrial approvals guarantee reliable performance and safety compliance.
This Littelfuse MICROSMD150F resettable fuse provides a reliable and compact solution for circuit protection in various electrical and electronic manufacturing, automation, and repair applications.
