The TS250-130F-RC-B-0.5-2 is a type of PTC resettable fuse which provides overcurrent protection for a variety of electrical and electronic applications. This type of fuse has become increasingly popular for its numerous advantages over traditional fuses. This article will discuss the application field of the TS250-130F-RC-B-0.5-2 and its working principle.

Application Field

The TS250-130F-RC-B-0.5-2 has a variety of applications, from consumer electronics such as digital cameras, GPS units, and laptops to industrial applications such as motors, robotics, and solar power systems. PTC resettable fuses offer the benefit of being overcurrent protection and self-resettable. This means that once an overcurrent has occurred, the fuse will automatically reset itself as long as the current does not exceed the fuse’s maximum ratings, allowing the circuit to remain in operation. They are also safer and more reliable than traditional fuses as the chances of an open circuit is minimized and the risk of fire from arcing is eliminated.

Due to their unique characteristics, PTC resettable fuses are also used in the automotive industry, providing overcurrent protection in vehicles’ electrical systems. For example, they are often used in areas such as starter motor circuits, audio systems, and airbag deployment systems, where an extra layer of protection is needed to ensure the safety of passengers.

Working Principle

PTC resettable fuses have an unrestricted overcurrent current response, which means that the fuse will respond to any overcurrent as soon as it is detected. The fuse contains a special plastic resistor which is connected in series with the primary winding of an electromagnet. When the overcurrent flows through the fuse, the heat generated by the current causes the plastic resistor to increase in resistance. This results in a dramatic increase in the current through the primary winding of the electromagnet and an increase in the magnetic field. This, in turn, causes the contacts of the electromagnet to open, thus interrupting the circuit and protecting it from further damage.

When the current returns to a safe level, the electromagnet’s contacts will close again, allowing the circuit to resume normal operation. This process happens quickly and is very efficient in protecting the circuit from the overcurrent.

The TS250-130F-RC-B-0.5-2 PTC resettable fuse is a reliable and effective way to protect a circuit from overcurrents. It offers numerous advantages over traditional fuses, including increased safety, protection, and reliability. Furthermore, the ability of the fuse to self-reset makes it especially suitable for protecting circuitry that is experiencing frequent overcurrents. Therefore, the TS250-130F-RC-B-0.5-2 are suited for a variety of automotive, consumer, and industrial applications.
