Littelfuse 6V dc Resettable Fuse 0.55 A Hold Current 100 A Current Rating PICOSMDC050S-2

Littelfuse PICOSMDC050S-2 resettable fuse is engineered for protecting electrical and electronic circuits from overcurrent conditions and short circuits. This device operates at a voltage of 6V dc and holds a current of 0.55 A, switching rapidly to a high resistance state during fault conditions and automatically resetting once power is removed.

The compact polySwitch nanoSMDC series fuse features surface-mount technology, eliminating the need for fuse holders and enabling easy integration into compact circuit designs. With a trip current of 1.25 A and a fast 0.1 second time to trip, it offers precise and reliable circuit protection.

Capable of handling current ratings up to 100 A, this fuse uses tin terminal material to ensure stable electrical connections and low resistance. It maintains its performance within a broad temperature range from -40°C to +85°C, making it suitable for industrial, automotive, medical, audio-visual, and telecommunication applications.

The device dissipates power up to 0.5 W efficiently and complies with RoHS standards, reflecting its environmental safety credentials. Packaging in reels supports high-volume automated insertion processes.

Applications for this Resettable Fuse include security systems, power supplies, power switching devices, instrumentation and control systems, and peripheral computer equipment where reliable circuit protection is critical.

Automatically resets after fault condition clears, ensuring maintenance-free operation. Compact nanoSMDC series surface-mount design suitable for space-constrained circuits. Trip current precisely set at 1.25 A with 0.1 second response time.
