Product Description
Littelfuse 2920L100PR resettable fuse delivers reliable overcurrent protection with a hold current of 1.1 A and a dc voltage rating of 33 volts. This surface mount fuse is designed for applications where space is constrained and automatic resettable protection is needed.
The 2920L series fuse switches rapidly from low resistance to a high resistance state during electrical faults such as overloads or short circuits. It automatically resets once the fault condition clears and power is removed, enabling maintenance-free operation for thousands of cycles.
Constructed with tin plated copper terminals, the fuse ensures excellent electrical conductivity and durability. The fuse features a compact form factor with a length of 7.98 mm, width of 5.44 mm, and height of 1 mm, suitable for surface mount PCB assembly.
Operable over a temperature range from -40°C to 85°C, it dissipates power up to 1.5W and maintains reliable performance. Its trip current is specified at 2.2 A with a current rating of 40 A.
This component is RoHS compliant, making it environmentally friendly and safe for use in various electronics and electrical systems.
Applications include use in automotive equipment, medical devices, instrumentation and control gear, security systems, power supplies, transformers, audio visual equipment, computers, and telecommunication devices.
