PTC Resettable Fuses are a type of thermal protection device which can receive protection against current overload, short circuit, and over temperature in various electronic systems. The B59073R0080B010 is a PTC Resettable Fuse that is designed to protect high-power applications like power converters, LED lighting, and motor drives. This PTC has a high thermal cycling capability for life cycle warranties so it can handle frequent thermal cycles from overcurrent or over temperature events without failure. This PTC is also designed for fast self-resetting for applications with multiple overloads over the life of the product.

B59073R0080B010 Application field
The B59073R0080B010 is designed for uses such as power supplies, LED lighting, motor drives, switching power supplies, power converters, aviation connectors, and automotive power modules. This PTC is capable of operating under temperatures ranging from -40°C to +125°C and provides reliable current protection even in harsh thermal environments.

B59073R0080B010 Working Principle
The B59073R0080B010 utilizes a polymeric Positive Temperature Coefficient (PTC) to provide overcurrent protection. This PTC melts at temperatures above its nominal rated trip current and as it melts, it increases its resistance, reducing the current to a safe level. Once the current is reduced, the PTC cools and its resistance returns to its normal low state. This action of melting and cooling can be repeated multiple times, providing a short-term protection system for applications with multiple overloads.

When an overcurrent or over-temperature event occurs, the B59073R0080B010 PTC heats up and its resistance increases rapidly. This rapid increase in resistance restricts the flow of current and reduces it to a safe level. The PTC then cools and its resistance returns to its normal low level. This action is repeated multiple times providing short-term protection to the application.

The B59073R0080B010 PTC is specifically designed for high power applications and can carry currents up to 5 amps. It is also capable of withstanding up to 4 kgf of pull force and can operate under high vibration environments. It has a fast reset time of 8 ms and can operate over a wide temperature range of -40°C to +105°C. This PTC also has a high thermal cycling capability so it can withstand multiple thermal cycles without any permanent damage.

The B59073R0080B010 PTC Resettable fuse is a reliable and cost-effective solution for high power applications. It is capable of providing protection against current overload, short circuit, and over-temperature events. This PTC can also withstand multiple thermal cycles without any permanent damage. It is highly reliable and provides reliable current protection in harsh environments.
