B59502R0130B010

PTC Resettable Fuses are commonly used in many different types of electronic devices, usually to protect the device from short-circuiting, over-current, and overload. The B59502R0130B010 is a type of Polymeric Positive Temperature Coefficient (PPTC) Resettable Fuse, and is used for a variety of applications. This article will focus on the application field and working principle of the B59502R0130B010.

Application Field of the B59502R0130B010

The B59502R0130B010 has a wide range of applications, particularly in industrial, automotive, and consumer electronics. It is commonly used in switching power supplies, power supplies of TVs and computer monitors, inverters, electric tools, and charge pumps. This device is also used as an over-current protection in devices such as Lithium battery packs, DC Motors, Lighting Systems, and DC/DC Converters. Furthermore, this PTC Resettable Fuse is often used in many home appliances, including microwaves, kitchen appliances, air conditioners, fans, printers, and vacuum cleaners.

Working Principle of the B59502R0130B010

The B59502R0130B010 uses a sense fuse technology that responds to both over-current and over-temperature conditions. This device contains a ceramic body coated with a polymeric material that acts as the resistive element. Above the Curie point temperature the resistivity of this material increases, resulting in a rapid increase in the resistance and thus limiting the current.

The device is designed with a certain trip current and a temperature range. When the current that passes through the device exceeds the trip current of the fuse, the temperature and resistivity of the device rises. This increase in resistivity causes the current to be limited, protecting the device from damage. When the temperature is reduced below the Curie point temperature, the resistivity decreases and the device is reset. This allows the device to be used for repeated over-current protection.

Conclusion

The B59502R0130B010 is a PTC Resettable Fuse used for a wide variety of applications. This device is commonly used in products such as switching power supplies, power supplies of TVs and computer monitors, inverters, electric tools, and charge pumps. It works by using a sense fuse technology that responds to both over-current and over-temperature conditions, limiting the current to protect the device from damage when needed. With its wide variety of applications and unique working principle, the B59502R0130B010 is an excellent choice for PTC resettable fuse protection.
