PTC Resettable Fuses, or Polymer Positive Temperature Coefficient Resettable Fuses, are a form of self-resetting fuse that offer both over-temperature and short-circuit protection to electronic components and computer systems. PTC Resettable Fuses are composed of a ceramic core material and a metal or copper heat sink. When an over-current or short-circuit condition occurs, the core material becomes resistive and increases in temperature, causing the heat sink to draw off the current, thereby preventing the damage that would be caused by a standard fuse. PTC Resettable Fuses are one-time devices, meaning that once they are heat-activated, they will remain in an inactive state until the temperature returns to normal.

The 0ZRC0375FF1A PTC Resettable Fuse is a fast-acting, 250mA, resettable fuse, measuring 3.6mm by 4mm by 0.6mm with a thermal rating of 6A. It features a high tolerance for current inrush, making it ideal for applications such as LCD backlighting for TVs and computer monitors. Additionally, the 0ZRC0375FF1A can be used in the applications detailed below:

• Automotive Chargers and Batteries
• Set-Top Boxes
• Power Supplies
• Adapters
• GPS Devices
• Printers and Copiers

The 0ZRC0375FF1A PTC Resettable Fuse is a one-time device, meaning that once it is activated, it will remain in an inactive state until the current returns to normal. Additionally, the 0ZRC0375FF1A has a low voltage dropping capability, making it ideal for applications with a wide input voltage range.

The 0ZRC0375FF1A PTC Resettable Fuse is constructed from high grade ceramic and comes in a compact SMD package, making it easy to install in printed circuit boards. It also has a low rooftop voltage, which makes it ideal for use in low voltage systems. Additionally, this fuse has a low holding voltage, which helps to ensure steady current flow and prevents any current leakage. Furthermore, the 0ZRC0375FF1A PTC Resettable Fuse is resistant to vibration and shock, making it ideal for use in automotive, audio, and medical electronics applications.

The working principle of a 0ZRC0375FF1A PTC Resettable Fuse is fairly simple. When a fault or overload occurs, the high-temperature thermistor (thermally activated fuse) increases in resistance, limiting the flow of current. This causes the heat sink to draw off the current, thus, preventing damage caused by a standard fuse. It also prevents current leakage, ensuring steady current flow. Once the fault or overload condition has cleared, the 0ZRC0375FF1A PTC Resettable Fuse will reset itself and return to its low resistance state, allowing the current to flow again.

The 0ZRC0375FF1A PTC Resettable Fuse is an ideal device for providing over-temperature and short-circuit protection in a variety of applications. Its fast-acting, low voltage dropping, and high tolerance for current inrush make it ideal for use in LCD backlighting, automotive chargers and batteries, set-top boxes, and power supplies, among many other applications. Additionally, its compact SMD package and low rooftop voltage make it perfect for use in low voltage systems. The 0ZRC0375FF1A PTC Resettable Fuse works by activating when a fault or overload occurs, increasing in resistance, and causing the heat sink to draw off the current. Once the fault or overload condition has cleared, the fuse will reset itself and return to its low resistance state, allowing the current to flow again.
