Product Description
The Littelfuse 1206L050YR is a 0.5 Amp resettable fuse designed to provide reliable overcurrent protection for electronic and electrical circuits. It is constructed with surface mount technology in the compact 1206L series package, which makes it ideal for applications where PCB space is limited.
This resettable PTC device rapidly transitions from a low resistance state to a high resistance state upon detecting an overcurrent or short circuit condition, limiting current flow and preventing damage. Once the fault is cleared and power is removed, the fuse automatically resets to its original low resistance state without any replacement needed, offering maintenance-free operation for thousands of cycles.
The fuse features a hold current of 0.5 A and a trip current of 1 A, providing precise protection levels for sensitive electronic components. It has a response time of 0.1 seconds ensuring quick operation to protect circuits effectively.
The package size is 1206 with dimensions of length 3.4 mm, width 1.8 mm, and height 0.75 mm. Terminal material is tin plated copper for consistent soldering and connection quality. Its resistance ranges from 0.15 Ω minimum to a maximum of 700 mΩ, suitable for a broad range of low voltage dc applications up to 6V dc.
Operating temperature ranges from -40°C to 85°C, making it suitable for use in automotive, medical equipment, security systems, power supplies, power switching devices, instrumentation, control systems, computers, audio visual, and telecommunications fields.
This resettable fuse is RoHS compliant, ensuring it meets environmental and safety standards. The Littelfuse 1206L series is designed to improve production efficiency by being supplied on reels ready for machine insertion.
This product is ideal for applications requiring automatic resettable overcurrent protection with minimal board space and maintenance. Explore more products in the Resettable Fuse category to find compatible protective components for your industrial and commercial electronic assemblies.
