PTC Resettable Fuses, commonly referred to as polyfuses, are considered to be a reliable form of overcurrent protection, especially in the presence of lightning or other disturbances. These types of safety devices are designed to protect circuits against overcurrents and short circuits for industrial and consumer applications.

Among them, the MF-RHT100-AP is a surface mount, polymeric positive temperature coefficient (PPTC) resettable fuse specifically designed for the transient overcurrent protection of automotive applications in today’s small form factor products. These MF-RHT100-AP devices are designed to provide high current over current protection for a wide range of power supplies, motors, consumer electronics and many other applications.

The MF-RHT100-AP operates by allowing an overcurrent to flow until the current reaches a predetermined level. The heat generated by the current then increases the temperature of the device and causes it to open. When the fault is removed, the device will reset and allow current to flow again. This resetting process can be repeated many times, making this type of fuse a reliable over current protection device.

The main features of the MF-RHT100-AP include its high current rating (100A at 32V DC maximum), low power consumption (<1 mA @ 5V DC), low temperature coefficient, and its fast activation time of less than 1 millisecond. The device is also rated for a wide operating temperature range (-40 °C to +125 °C) and is qualified according to AEC-Q200 and SAE J1284.

The main applications of the MF-RHT100-AP are in automotive and industrial applications. In the automotive sector, the device can be used to protect devices such as power supplies, motors, battery backup systems, and other types of electrical current. In industrial applications, the device can be used in high power installations, such as those found in wind turbines, electrical substations, and other large current applications. The device is also suitable for consumer electronics, such as personal computers, laptops, tablets, and other consumer electronic products.

In summary, the MF-RHT100-AP is specifically designed to provide overcurrent and short circuit protection for automotive and industrial applications, utilizing its fast response time and high current rating. This type of PTC Resettable Fuse is suitable for many types of applications, ranging from consumer electronics to high-power installations including wind turbines and substations. The device is also qualified to AEC-Q200 and SAE J1284.
