PTC Resettable Fuses, commonly known as Polymer Positive Temperature Coefficient Resettable Fuses, are devices designed to protect circuits from excessive current. Taking B59860C0130A070 as an example, this part of the PTC Resettable Fuses family uses a small zinc-metal-oxide resistance element as the sensing element for an overcurrent situation. When overcurrent flows through, the zinc-metal-oxide element heats up and acts as a temperature-sensitive switch in the circuit. This switch will then switch to its high-impedance state, thereby tripping the circuit and limiting further current flow. This self-resetting PTC fuse can reset simply by cooling off, which is a great benefit compared to traditional magnetic circuit breakers.

The B59860C0130A070 PTC Resettable Fuses are typically used to protect power supplies, computer systems, and portable electronics from potential current damage caused by short circuit, inrush current, static electricity buildup, or other overload conditions. The device can handle a voltage range of 6V-36V DC and has an internal impedance of 0.1 ohms. It has a trip current of 103A and a hold current of 7.3A. The device is also designed to withstand 65A (1A -8/20μs) of surge current.

The working principle of the B59860C0130A070 PTC Resettable Fuse is simple. When connected appropriately in a circuit, the zinc-metal-oxide element acts as a temperature-sensitive switch and triggers when current overload occurs. This triggers the switch to its high-impedance state, thereby tripping the circuit, and cutting off further current flow. Once the over-current situation is corrected, the device can be reset simply by cooling off and the device is ready to protect the circuit again.

The B59860C0130A070 PTC Resettable Fuses are ideal for use in applications such as computer power supplies, laptops, LCD displays, routers, 3D printers, robotic arms, telecommunication systems, solar systems, and in many other high-current applications.

In conclusion, the B59860C0130A070 PTC Resettable Fuses are designed to protect circuits from excessive current. The device uses a small zinc-metal-oxide resistance element as the sensing element to trigger the switch to its high-impedance state in the event of an overload. The device will then reset itself simply by cooling off. The device is suitable for use in a variety of high-current applications such as laptops, computers, solar systems, and more.
