Polymer positive temperature coefficient (PTC) resettable fuses are a type of thermal protection device that provide protection from overcurrent and overvoltage. They are widely used in a variety of applications in industrial, commercial, and consumer electronics. The PRG18BC2R2MM1RB PTC resettable fuse is one such device which is designed for high current applications.

The PRG18BC2R2MM1RB is a radial lead, surface mount device designed for use in circuits where high current capacity and resettable protection is required. It features a current rating of 18A, voltage rating of 250V, and operating temperature range of -55 to +125⁰C. The device is constructed from a high temperature Polyurethane with a varnished copper wire, and has two expanding terminals on either side of the center body for easier mounting and increased contact area.

The working principle of the PRG18BC2R2MM1RB is based on the characteristics of a positive temperature coefficient (PTC) device. When there is an overcurrent or overvoltage condition, the temperature of the device increases which causes the element to expand and increase resistance. This increased resistance limits the current through the device and helps protect it from damage. When the fault condition is removed, the device will cool, resulting in a decrease in resistance and allowing the circuit to operate normally.

The PRG18BC2R2MM1RB is commonly used in applications such as power buses, inverters, DC/DC converters, and automotive electronic control systems. It is also used in consumer electronics and applications where reliable and resettable overcurrent protection is required. This device can also be used as a thermal cutout or self-resetting fuse for DC circuits on high current circuit boards.

In summary, the PRG18BC2R2MM1RB PTC resettable fuse is a high current device that provides reliable overcurrent and overvoltage protection. It is a surface mount device with two expanding terminals for easy mounting and increased contact area. It can be used in a variety of industrial, commercial, and consumer electronics applications including power buses, inverters, DC/DC converters, automotive electronic control systems, and high current circuit boards.
