0LGR003.H

Fuses are devices that protect electrical circuits against overloads and short circuits. They contain a small strip of metal, which melts and opens the circuit if the current becomes too high. The 0LGR003.H is a type of fuse that can be used in a variety of applications. In this article, we will look at the application field and working principle of the 0LGR003.H.

Application Field

The 0LGR003.H is a chip-type fuse, and is often used in circuit boards and other small electronic devices. It is particularly suitable for automotive and industrial applications, where space is at a premium. Other applications include phones, games consoles, audio-visual equipment, computers and other devices.

The 0LGR003.H is a Type 2 fuse, which means it is designed to protect the circuit from overloads. This means that it will trip if the current exceeds the rated value, and will open the circuit to prevent damage to the components. It also has a high breaking capacity, meaning it is able to trip at higher currents than other fuses.

The 0LGR003.H is also a resettable fuse, which means it will reset itself once the current has fallen below a certain level. This makes it especially suitable for scenarios where the current fluctuates rapidly or where the current is likely to remain above the rated value for extended periods of time.

Working Principle

The 0LGR003.H is a resettable chip fuse, meaning it has two components: a resistor and a thermal fuse element. The resistor is designed to reduce the current passing through the fuse, while the thermal fuse element trips the fuse if the current exceeds the rated value.

When the current passes through the resistor, some of the energy is converted into heat. This heat is then dissipated into the thermal fuse element, which is made from a special material that melts at a specific temperature. When the temperature rises above this threshold, the element melts and opens the circuit. This opens the circuit for a fraction of a second, allowing the current to drop below the rated value before the element resets itself.

The 0LGR003.H also has a number of other features that make it suitable for a variety of applications. It has self-limiting characteristics, meaning it can withstand short-term overloads without opening the circuit. It also has a low temperature coefficient, meaning it is less likely to open the circuit due to temperature changes. In addition, it is also UL certified, meaning it meets the highest industry standards for safety.

Conclusion

The 0LGR003.H is a resettable chip fuse that is suitable for a variety of applications. It offers a high breaking capacity and can withstand short-term overloads without opening the circuit. In addition, it is UL certified, meaning it meets the highest industry standards for safety. As a result, it is a popular choice for automotive, industrial and other electronic applications.
