PTC Resettable Fuses are widely used in electronic protection. They are simple, reliable, and effective in providing overcurrent protection for both low and high loads. The RXEF030S-2 is a compact PTC resettable fuse designed for protection against overcurrent. It consists of a single chip PTC element and substrate that is rated to handle up to 30 A and can reset itself upon the removal of fault current.

The RXEF030S-2 has a compact form factor and low profile design making it well suited for applications where space is limited. The PTC element has a wide operating temperature range and low leakage current. It has a low hold current of 0.062 A and a high operating current of 30 A. The device is suitable for reverse voltage blocking, reverse current blocking, and surge current protection.

The RXEF030S-2 has a number of applications in portable electronics, telecommunications, consumer electronics, industrial and automotive systems, and computer peripherals. It can provide reliable protection for a range of applications such as batteries, LED lights, motors, power controllers, and circuit breakers. It is particularly well suited for high load surges or low voltage circuits.

The working principle of the RXEF030S-2 is based on the use of a PTC element in combination with a substrate. The PTC element is a semiconductor material with a very low resistance when the current is below a certain threshold. When the current exceeds the threshold, the resistance of the material increases and the device acts as a high-impedance switch. This in turn causes the current through the device to drop and the device resets itself once the fault current is removed.

The RXEF030S-2 is designed with an internal electronic protection circuit that monitors the current in the PTC element. In normal operation, the circuit prevents any current from exceeding the operating current. When an overload occurs, the current in the PTC element rises and exceeds the operating current, triggering the internal protection circuit and limiting the amount of current that can flow. This provides protection against both overcurrent and short circuits, ensuring that the device will not be damaged in the event of a fault.

In addition to providing protection against overcurrent and short circuits, the RXEF030S-2 also has a number of features that make it well suited for use in sensitive applications. It has a fast response time of less than 1µsec, which minimizes the risk of damage to sensitive components. In addition, it has an overshoot voltage protection that prevents voltages from exceeding a certain level in the event of a fault.

The RXEF030S-2 is a reliable and robust PTC resettable fuse that provides effective protection against overcurrent and short circuits. It has a wide operating temperature range and low leakage current. Its low hold current and high operating current make it ideal for a range of applications. The fast response time and overshoot voltage protection further enhance its reliability.
