02200003DRT2P

Fuses are an essential component of safety within electronic systems and are designed to prevent malfunction and damage from current overloads and short circuits. 02200003DRT2P is a type of fuse specifically designed to safeguard semiconductors against the damaging effects of over voltage and short-circuiting. This article will provide an overview of the application field and working principle of 02200003DRT2P.

Application Field

The 02200003DRT2P can be used to protect high power DC circuits, AC circuits, electronic control systems, converters, switching power-supplies, motors, radiators, and lighting systems from over voltage and short-circuits. It is often found in data centres, industrial equipment, electrical appliances, and automotive applications. With its high current-overload protection and fast response, the 02200003DRT2P is well-suited to protect demanding applications.

Working Principle

The 02200003DRT2P is a type of resettable fuse, also known as a Polymer Positive Temperature Coefficient (PPTC) fuse. A PPTC fuse consists of a polymer element sandwiched between two conductors and is designed to respond quickly to an over voltage or short-circuit event. When the current through the device reaches the specified overload value, the polymer element heats up and quickly expands, causing the two conductors to separate and interrupt the current flow. When the current is removed, the polymer element cools and contracts, allowing the two conductors to reconnect and allowing the current to flow again.

Despite its fast response to an over voltage or short-circuit event, the 02200003DRT2P is very reliable and offers very low standby power losses, making it suitable for various mission-critical applications. Furthermore, the device is also designed to be much more resistant to rapid voltage transients, compared to other types of resettable fuses.

Conclusion

In conclusion, the 02200003DRT2P is a type of resettable fuse specifically designed to protect circuits against the damaging effects of over voltage and short-circuiting. It can be used to protect high power DC circuits, AC circuits, electronic control systems, converters, switching power-supplies, motors, radiators, and lighting systems. Its fast response time and reliable protection make it suitable for mission-critical applications and it is often found in data centres, industrial equipment, electrical appliances, and automotive applications.
