Product Description
Littelfuse RUEF500 Resettable Fuse is a robust circuit protection device engineered for electrical and electronic applications requiring a 5 amp hold current and 30V dc voltage rating. It features radial lead design enabling easy application in PCB wire-ended configurations.
This fuse rapidly transitions from a low resistance state to a very high resistance state when an overload or short circuit occurs, effectively protecting the circuit from damage.
The fuse automatically resets itself thousands of times without the need for replacement, providing a maintenance-free solution with a compact size that eliminates the need for fuse holders.
Certified to stringent industry standards including TUV, RoHS, CQC, CSA, and UL, the fuse ensures compliance and reliability in demanding environments.
Power dissipation up to 3W supports stable operation during current surges, while its operating temperature range from -40°C to 60°C suits diverse industrial and commercial conditions.
Typical applications include security systems, power supplies and transformers, power switching devices, automotive and medical equipment, instrumentation, control systems, computers, peripheral devices, audio visual, and telecommunications equipment.
Automatically resets thousands of times without replacement. Radial lead orientation for easy PCB mounting. Maintains circuit integrity by switching to high resistance on faults. No fuse holder required, saving space and maintenance costs.
Meets multiple international safety and quality standards. Compact dimensions allow flexible system integration. Wide operating temperature range for various environments. Power dissipation capacity supports surge loads effectively.
Reliable series RUEF range ensures consistent performance. Suitable across industrial, laboratory, automotive, and communications sectors. Explore more high-quality fuses and resettable circuit protection devices in the Electronics & Electricals category at EnvMart.
