PTC resettable fuses, or polymeric positive temperature coefficient (PPTC) fuses, are becoming increasingly popular components in modern electronic circuits. A PTC fuse acts like a normal circuit breaker, being able to detect and protect against dangerous overcurrents and shorts. What makes a PTC different to a circuit breaker is that it can automatically reset itself after the fault has been removed. This makes them ideal for always-on and exposed circuits where access is limited, and also means they are suitable for basic overcurrent protection.

0ZSC0190FF1E is a low resistance PTC resettable fuse with a variety of applications. It combines the advantages of low resistance and good thermal response with a high current rating for protecting against dangerous overcurrent events. The device’s reset resistance is a reliable 4 ohms and features a nominal hold current of 6.5 amps and a maximum voltage rating of 14.5 volts.

Over-currents are common in the automotive industry and can cause significant damage to cars. 0ZSC0190FF1E helps prevent this by providing fast and reliable protection from these types of events. It can reset itself after an over-current event, saving time and resources for replacing blown fuses, and minimising the risk of injury or damage. This makes it the perfect choice for automotive applications such as batteries, chargers, power supplies and other automotive circuits.

In addition, 0ZSC0190FF1E is suitable for use in a wide variety of other applications. It is often found in consumer electronics, industrial control systems, lighting and electrical systems, as well as home appliance control systems. Its reliable protection from over-currents makes it a great choice for any circuit where safety and reliability are paramount.

The working principle of 0ZSC0190FF1E is based on the principle of thermally actuated self-resetting protection. When a predetermined overcurrent level is detected, the device will generate heat which will increase its internal resistance. As the resistance of the device increases, the current flowing through it is reduced, effectively resetting the fuse. Once the fault has been cleared, the device will cool down and reset itself to its original condition.

In summary, 0ZSC0190FF1E is a reliable and efficient resettable fuse ideal for automotive, consumer electronics, industrial control systems and home appliance control applications. Its ability to rapidly detect dangerous over-currents and reset itself after the fault has been eliminated makes it an extremely valuable component in modern circuits.
