PTC resettable fuses, or Polymer-Positive Temperature Coefficient Resettable Fuses, are a type of electricity-limiting components that provide dual-level protection for equipment, systems, and components. They are designed to protect against both excessive current draw, as well as overvoltage. The B59890C0160A051 is a PTC resettable fuse used in a wide variety of applications, and it has a unique and effective working principle.

The B59890C0160A051 works by combining two temperature-dependent mechanisms. In the first mechanism, there is a polymeric material that has a highly temperature-sensitive resistance. When exposed to a current above a certain threshold level, the temperature of the polymer will rapidly increase, causing its resistance to increase. This increased resistance limits the current that can flow through the component. In the second mechanism, another temperature-dependent property of the polymer causes it to have a positive temperature coefficient, meaning that when the temperature of the polymer increases, its resistance quickly increases. This prevents any further increases in current.

The B59890C0160A051 is used in many applications such as consumer electronics, automotive systems, security systems, lighting systems, and computer power supplies. In consumer electronics, it is used as a protection device to limit the current draw on components that do not have a fuse or other over-current protection. In automotive systems, it is used as an electrical current limiter, protecting the wiring and components from over-current conditions. In security systems, the PTC fuse is used to protect the control system from overvoltage conditions, preventing damage to sensitive components and wires. In lighting systems, it is used to protect sensitive lighting components from over-current conditions. In computer power supplies, the PTC fuse is used to protect the circuitry from over-temperature conditions.

The working principle of the B59890C0160A051 is simple yet effective. When exposed to a current above a preset threshold, it quickly limits the current flow, protecting the circuitry from damage. The fuse then resets itself and is ready for use again. This makes it one of the most reliable and cost-effective protection mechanisms available on the market today.

The B59890C0160A051 is a reliable and efficient PTC resettable fuse that has been designed for use in a wide variety of applications. It combines two temperature-dependent mechanisms to provide dual-level protection, and it is designed to protect against both excessive current draw, as well as overvoltage. It is a cost-effective and reliable protection device that is easy to install and use. As such, it is an excellent choice for protecting sensitive electronics and systems from damage due to over-current and overvoltage.
