PTC Resettable Fuses are a type of fuse designed with self-resetting properties, meaning that the fuse will trip or “open” after a certain amount of current passes through it, and will then automatically recent when the current passes below a predetermined level. This ability makes them desirable in many different applications, including the PRG18BB471MS1RB fuse, which is designed to provide circuit protection for 12-volt automotive systems.

PRG18BB471MS1RB Application Field

The PRG18BB471MS1RB belongs to a family of PTC fuses designed for use in the automotive market. This fuse has a hold current rated up to 4.7 Amps and a rated voltage of 125VAC. This fuse is suitable for use in a wide variety of 12-volt automotive applications, including automotive electric windows, motors, and starter circuits.

PRG18BB471MS1RB Working Principle

The PRG18BB471MS1RB functions by using a polymeric positive temperature coefficient (PPTC), which increases its resistance with increasing temperature. This behavior prevents the current from exceeding a set level, thus providing protection against hazardous short-circuit conditions. The PPTC also exhibits self-resetting properties, meaning that the fuse will reset itself after the temperature drops. The PRG18BB471MS1RB has a thermal cutoff temperature of 150°C, which will trip the fuse if the current exceeds 4.7 Amps at any time.

The PRG18BB471MS1RB is a very reliable and suitable fuse for most 12-volt automotive applications. It provides circuit protection in a variety of scenarios, including over current, short circuit, and overload protection. In addition, the PRG18BB471MS1RB is RoHS compliant and is UL recognized.

In conclusion, the PRG18BB471MS1RB is a reliable PTC resettable fuse that is designed to provide circuit protection in a variety of 12-volt automotive applications. This fuse has self-resetting properties, a hold current of 4.7 Amps, and a thermal cutoff temperature of 150°C. In addition, it is RoHS compliant and UL recognized, so it provides a safe and reliable form of circuit protection.
