Product Description

Littelfuse MICROSMD010F-2 is a 0.1 Ampere, 30 Volt DC PolySwitch Resettable Fuse designed for protection of electrical and electronic circuits. Its surface mount technology with SMT footprint 3225 ensures compact integration in modern PCB designs.

The device handles trip currents of 250mA with a hold current of 0.1A, making it ideal for sensitive circuit protection against overloads and short circuits. The fuse transitions rapidly to a high resistance state within 1 second to prevent damage and automatically resets once the fault condition clears and power is removed.

It includes tin-plated terminals to ensure reliable connections and reliability over repeated cycles. The compact dimensions of 3.43mm length, 2.8mm width, and 0.85mm height allow space-efficient applications. It withstands maximum operating temperatures up to 85°C and dissipates power up to 0.8 Watts.

The polySwitch Micro SMD series fuse provides maintenance-free protection with an expected life of thousands of reset cycles, suitable for applications in power supplies, transformers, and automotive electronics.

Main application areas include security systems, medical equipment, instrumentation and control, computers, audiovisual, and telecommunications devices requiring robust current protection with automatic reset capability.

Features a trip current of 250mA for sensitive overcurrent protection. SMT footprint 3225 (metric) for board mounting. Voltage rating of 30V DC with hold current at 0.1A. Rapid resettable operation for repeated use. Compact size and tin-plated terminal material.

Power dissipation rating of 0.8 Watts. Maximum operating temperature of 85°C. Maintenance-free automatic reset for thousands of cycles. Low resistance characteristics between 2.1Ω minimum and 15Ω maximum. Reliable in industrial, commercial, automotive, and electronic circuit protection use cases.
