Introduction: PTC Resettable fuses, also known as polymeric positive temperature coefficient (PPTC) fuses, are electronic protection devices designed to protect the circuit from a fault current or an overload. The fuse will trip and reset automatically depending on the current passing through it.

MINIASMDC075F/24-2 application field and working principle:The MINIASMDC075F/24-2 is a PTC resettable fuse designed for a high ambient temperature, up to 155°C. It is suitable for use in automotive, industrial, marine, and military applications. The fuse limits the peak current, which helps to avoid circuit board component damage and increases the safety level. The fuse is designed with two terminals, and can be used in either a low power or high power circuit. It has an operating voltage of up to 24 volts and a continuous operating temperature range from -55°C to 155°C.

The fuse works by sensing the current flowing through it. When the current reaches the predetermined cut-off point, the element inside the fuse is heated up so much that it melts and disconnects the circuit. This will cause a drop in current before it reaches the point where it can cause any damage. After the current drops, the fuse will cool down and reset. The amount of time it takes for the fuse to reset depends on the rated value of the current, the ambient temperature, and other factors.

The fuse also features an internal short-circuit protection and an over temperature protection. The internal short-circuit protection prevents the circuit from being damaged by a high current short circuit. The over temperature protection helps protect the fuse from high temperature environments, which can cause damage to the fuse element.

The fuse also has a wide variety of operating characteristics which can be used in circuits with low, medium, or high currents. It can also be used in a variety of applications such as motor vehicle electronics, aerospace, and industrial applications. In addition, it is verified to international UL, IEC, and CSA standards.

Advantages:

• The fuse provides effective overcurrent protection and circuit operation.
• The reset time is fast, and the circuit can be reset within 1-3 milliseconds.
• It features an internal short-circuit protection and an over temperature protection.
• It is verified to international UL, IEC, and CSA standards.
• It can be used in a variety of applications such as motor vehicle electronics, aerospace, and industrial applications.

Conclusion:The MINIASMDC075F/24-2 is a PTC resettable fuse designed for a high ambient temperature, up to 155°C. It is suitable for a wide variety of applications, and it is verified to international UL, IEC, and CSA standards. The fuse provides effective overcurrent protection and circuit operation, and features an internal short-circuit protection and an over temperature protection.
