258GDQSJD20E

Electrical, Specialty Fuses

The 258GDQSJD20E is a type of electrical, specialty fuse. This kind of unit has a wide range of applications, from protecting electrical circuitry to acting as a safety device used to avoid possible fire or electric shock hazards. It also plays an important role in the capability of a circuit to detect dangerous shock and ground faults. This article aims to provide an overview of its application field and working principle.

Application Field

The 258GDQSJD20E fuse has the ability to protect a variety of electrical circuits. Its low IR drop element helps it to prevent overloading or short circuits in circuits with low power and low voltage. In general, it is suitable for use in power supplies, power converters, and low voltage DC circuits. It is also used in a variety of transformers, AC motors, and other circuits with higher current rating. The fuse also has the capacity to protect low voltage-drop devices, such as LEDs, circuit switches, and quartz crystals.

Working Principle

The 258GDQSJD20E works by interrupting the current flow in a circuit when the current exceeds its rated amperage or in case of a short circuit. It does so by creating an open circuit with an elemnt that melts when the fuse blows. During normal operation, there is no contact between the free fuse element and the holder. However, when the current flowing through the circuit exceeds the rated rating amperage, the free element melts and creates contact between the free element and the holder, thus creating an open circuit and breaking the circuit.

The 258GDQSJD20E is designed to operate at a specific temperature and this is indicated by its temperature coefficient, which signifies the temperature at which the fuse will blow. Generally, the higher the temperature coefficient, the higher the temperature operation and the quicker the blow time.

In conclusion, the 258GDQSJD20E is an important device for protecting electrical circuitry from damage due to overloading or short circuits. It is an element used in a wide range of applications and its working principle is based on creating an open circuit when the current exceeds its rated amperage. It is important to note that the fuse\'s temperature coefficient should be taken into account before selecting a fuse for a particular application.
