PTC Resettable Fuses

PTC resettable fuses are also known as Polymer Positive Temperature Coefficient (PPTC) devices. They are semiconductor devices made of polymers that are often used in power supplies and electronic circuits. The main advantages of PTC resettable fuses are that they are fast acting, reliable, and self-resetting, making them a good choice for a variety of applications. In this article, we’ll discuss the 1812L270SLPR application field and working principle.

Applications of 1812L270SLPR PTC Fuses

The 1812L270SLPR resettable fuse is often used in applications where there is a risk of short circuiting or over-currents. It is a suitable choice for controlling current in high-efficiency lighting, home electronic appliances, automotive and industrial electronic circuits. In addition, it is also found in medical electronics products and LED driver applications. The fuse can also be used as a safety feature in power supply applications, providing protection against the risk of over-currents.

Working Principle of 1812L270SLPR PTC Fuses

The PTC resettable fuse works through a heat-activated process; when the current passes through the device, it generates heat to increase the resistance of the device over time. When the temperature reaches a certain level, the resistance of the fuse increases significantly, limiting the amount of current passing through it. This limits the current flowing through the device, preventing it from overheating or short circuiting. When the current drops below a certain level, the resistance of the fuse will decrease, allowing the current to pass through again.

Advantages of 1812L270SLPR PTC Fuses

The 1812L270SLPR resettable fuse provides several advantages not found in other types of fuses. These include fast response time, high surge current capability and long service life. Furthermore, it offers increased safety due to its self-resetting nature, making it a good choice for applications that require a high level of safety.

The 1812L270SLPR resettable fuse is a low-cost solution that provides reliable and safe protection against over-currents and short circuiting. It is a versatile device with a variety of applications, making it a good choice for a variety of projects.
