PTC (Positive Temperature Coefficient) resettable fuses are secondary protection devices that are used to protect circuits from overloads and short-circuiting. The most common type of PTC resettable fuse is the CMF-RL25U-0, which is designed for low-voltage applications. It is a low-cost solution to electrically isolating and protecting circuits from high current surges. It is also known for its low thermal inertia, which helps to reduce the amount of power dissipation during transient overloads.
Application Field
The CMF-RL25U-0 is most commonly used for low-voltage applications such as low-voltage DC power supplies, handheld electronics, and other consumer electronics. It is also used in automotive, industrial, and medical applications. It can be used to protect against current surges as well as to limit inrush current in AC-DC power supplies.
Working principle
The CMF-RL25U-0 works by limiting the maximum current flow allowed through the fuse. It is a high-performance device with a fast response time that is designed to protect against overcurrents and short-circuits. When the maximum current flows through the fuse, it generates heat, and the PTC element in the fuse expands, reducing the cross-sectional area of the fuse. This reduces the current flow and thus prevents damage to the protected circuit. Once the overload has been cleared and the current flow returns to normal, the PTC element cools and contracts, allowing the cross-sectional area of the fuse to return to its original size and the fuse to become operational again.
The CMF-RL25U-0 is a reliable device and can be used for a wide range of applications. It is designed for low-cost protection of low-voltage DC circuits and is a popular and cost-effective solution for applications requiring secondary protection of circuits from current surges.
