PTC Resettable Fuses, also known as polyfuse, are a type of self-resetting fuse widely used in a variety of electrical and electronic applications. PFMD.260.2 is a type of resettable fuse that is designed to protect components from current overloads. It is suitable for use in a variety of circuit protection applications, including industrial, medical, consumer, automotive, and communication devices.

The PFMD.260.2 is a highly reliable device with a rated current of up to 6.0 A. It also has a wide temperature range of -55°C to 130°C and an operating time of less than 0.1 seconds. Furthermore, it has a low self-resistance, which allows for a fast recovery time. This self-resetting fuse is made of an encapsulating material that contains a micro-sized, self-resettable temperature-sensitive polymer with a dielectric strength.

The working principle of the PFMD.260.2 is based on the PTC (Positive Temperature Coefficient) effect. When an over-current is detected, the temperature of the fuse increases rapidly, triggering a PTC switch, which limits the current by reducing its flow. This causes the PTC element to become a resistor with a very high resistance. As long as the over-current condition persists, the resistance remains high, preventing any further current flow. When the over-current situation has been eliminated, the PTC element cools, restoring it to a low-resistance state and allowing current to flow normally.

The PFMD.260.2 is commonly used in many industrial and consumer protection applications. It is often found in circuit boards, switches, and other electric devices that require protection from over-currents. It is also used in automotive systems as a protector for a variety of devices including alternators, fuel pumps, and relays. This self-resetting fuse is also used in many consumer electronic devices, such as computers and cell phones, as a safety measure in order to protect the device from power surges.

PFMD.260.2 PTC Resettable Fuses offer many advantages over traditional fuses, such as their fast response time, their low self-resistance, and their wide operating temperature range. They are also effective in providing a reliable protection against over-currents, allowing for a safe and secure operation in a variety of electrical and electronic systems.
