Through Hole Resistors have been around for decades, and their varieties and applications have grown exponentially as technology has advanced. One of the most popular types of resistor is the PTF65200R00AXR6. This Through-Hole Resistor is designed for the application of relay protection in high-voltage systems.

The PTF65200R00AXR6 consists of a ceramic body with an outer metal sleeve and electrical insulation ring. The internal resistor alloy is used to provide the necessary current limit. This resistor is also available in a variety of mounting configurations to meet most circuit applications.

PTF65200R00AXR6 is suitable for use in low voltage and temperature high power circuits and motor drive circuits. The resistor is designed to provide reliable overcurrent protection and switching times of up to 4ms in high voltage systems. It can be used in combination with other resistors to provide protection against prolonged overvoltage and current transients.

The main feature of the PTF65200R00AXR6 is its overcurrent protection capability. The resistor consists of two layers of ceramic material with an outer metal sleeve and an electrical insulation ring. When the resistor is overloaded, the internal resistor alloy melts, and the external diode is activated to regulate the current limiting voltage and reduce the load on the circuit. This action ensures that the temperature rise of the resistor is maintained within the recommended range.

The PTF65200R00AXR6 has an operating temperature range of -55 to 125 Celsius, and a maximum permissible overcurrent limit of 500VAC. It can handle up to 30A of current, and the temperature rating is calculated using the Joule’s law. It also has a very low thermal resistance, which means that the heat generated by the resistor is dissipated quickly.

The PTF65200R00AXR6 has a wide range of applications. It is commonly used in power supplies, motor drives and switching circuits. It can also be used in low voltage circuits and low-power, high-frequency applications. It is also used in safety-critical and other special applications due to its high reliability and current limiting capabilities.

In conclusion, the PTF65200R00AXR6 is a high-power Through-the-Hole Resistor designed for the protection of relay protection circuits in high-voltage systems. It has a operating temperature range of -55 to 125 Celsius, and a maximum permissible overcurrent limit of 500VAC. It can handle up to 30A of current and has a very low thermal resistance, making it suitable for a wide range of applications.
