电路保护

Circuit protection devices protect electrical circuits from damage

Circuit protection devices are designed to prevent an unnecessary amount of current, and can become damaged to save other components in the electrical circuit. Circuit protection components can be semiconductors (like TVS diodes, circuit protection ICs, etc.) or non-semiconductors (like fuses, PTC Resettable Fuses, gas discharge tubes, etc.). Find the perfect component in our inventory, including circuit protection devices and discrete semiconductors, to deliver the performance your most challenging applications demand.
