This group includes components and devices designed to safeguard electronic circuits from damage caused by electrical faults such as overcurrent, overvoltage, and short circuits. Fuses: Provide overcurrent protection by breaking the circuit when the current exceeds safe levels. Circuit Breakers: Resettable devices that protect against overcurrent and short circuits in high-power applications. Surge Protectors: Shield circuits from voltage spikes caused by transient events like lightning or power surges. TVS Diodes and Varistors: Offer overvoltage protection by clamping or absorbing excess energy. These components are vital for ensuring the safety, reliability, and longevity of electronic systems in consumer, industrial, automotive, and communication applications.
