Product Description

Product Overview

Fuse resistors provide reliable circuit protection by automatically cutting off power supply during short circuits or near-short circuit conditions. These components effectively limit short circuit current to prevent damage to devices and power supply systems, containing potential damage to localized areas.

Key Features

Dual function as both fuse and resistor
Overcurrent protection with thermal fusing mechanism
Excellent heat dissipation capacity
Safety certified with flame retardant properties
High performance with low resistance values
Compact size with substantial load capacity

Applications

Primary Applications

Portable mobile devices (tablets, laptops)
High power devices and electric tools
Electric bicycles and mobility systems
Rechargeable lithium battery systems

Industrial Applications

Home appliances and consumer electronics
Medical equipment and healthcare devices
Automotive industry components
Railway and aviation systems
Military equipment and precision instruments
