PTC resettable fuses are an essential part of our everyday power distribution systems as they protect circuits by quickly cutting off power in case of a surge or short circuit. The RUSB110 is a highly sought after resettable fuse due to its unique ability to automatically reset itself after the overvoltage or overcurrent event is gone. This makes it ideal for applications in vehicles, consumer electronics, and other high-use electrical systems.

The RUSB110 includes a polymeric positive temperature coefficient (PPTC) device that is designed to protect devices and circuits from overvoltage and overcurrent conditions. The PPTC device operates based on the temperature of the heat-conductive substrate. When the limit of overvoltage or overcurrent is exceeded, the PPTC device starts to conduct current and the overcurrent causes the temperature to rise in the substrate until the PPTC device triggers to cut off the current.

The RUSB110 has a low self-reset voltage, which helps it recognize the overload condition quickly and cut off power. This process keeps the circuit from becoming damaged from the overvoltage or overcurrent. After the surge or short circuit is gone, the PPTC device cools down and the RUSB110’s self-reset circuit system turns the power back on.

The key features that make the RUSB110 a good choice for a resettable fuse include its fast response time, high current-carrying capacity, low self-reset voltage, and case temperature resistance. The RUSB110 is a great choice for applications like HVAC systems, electric motors, new and hybrid vehicles, automotive electronics, LED lighting, entertainment audio/video equipment, and more.

The RUSB110 is also a popular choice for consumer electronics, due to its ability to quickly respond to and recover from overvoltage. The low voltage of the RUSB110 helps it accurately detect and respond to spikes or shorts in the circuit, which helps protect the sensitive components of consumer electronics from damage.

In summary, the RUSB110 is an excellent resettable fuse for a variety of applications. It is able to quickly detect and respond to overvoltage and overcurrent events, protecting both the system and sensitive components from damage. Additionally, its low self-reset voltage and case temperature resistance make it a great choice for any application where resettable fuses are necessary.
