Chassis Mount Resistors are preferred in applications where power dissipation, size, and reliability are of primary importance. The choice of Chassis Mount Resistors depends upon the environment in which the resistor will be operating. The PFU1000-100KJ1 series is a popular choice for applications with medium-to-high power dissipation, requiring an element that is small in size and has reliable performance.

The PFU1000-100KJ1 Application Field

The PFU1000-100KJ1 series is a widely used, reliable and cost-effective resistive solution for power electronic applications. Its chassis-mounted design is a perfect fit for a wide range of applications, including motor, machine, control, and power systems. It is ideal for noise or corrosion suppression, protection against over-voltage or under-voltage, and for balancing or smoothing applications. This device can also be used in areas such as lighting solutions, haptic solutions, and even aerospace applications. The PFU1000-100KJ1 series is designed with power levels ranging from 100 up to 1,000 Watts, with resistance values from 10mΩ up to 0.1Ω, offering a broad array of uses.

Construction and Design

The PFU1000-100KJ1 series is constructed using ultra-fully-diffused (UFD) metal-oxide semiconductor field-effect transistors (MOSFETs), with resistance element made of various low-temperature coefficient (LTC) materials. Its robust construction ensures uniform temperature distribution and high resistance stability over life. Its air-insulated design eliminates noise from adjacent circuitry, improving Isolation and protection. The PFU1000-100KJ1 series also helps to minimize the risk of fire, as compared to systems that use metal-clad resistors.

Working Principle

Chassis Mount Resistors like the PFU1000-100KJ1 series are operating on the principles of thermal and electrical resistance. When an electrical current flows through the resistor, the contacts or plates heat up, generating thermal energy. This energy is dissipated in the form of heat, which is conducted away from the resistor by the mounting plate and chassis. On the other hand, an electric current flowing through the resistor experiences a resistive force caused by the contact of the electrical components. The resistance element ensures that a precise amount of electrical energy is lost, providing the desired current limit.

Advantages and Features

The PFU1000-100KJ1 series is designed to provide a reliable current limiting and temperature controlling solution. Its highly efficient thermal design eliminates the need for a fan or other cooling system, as its non-inductive construction reduces noise interference from other components. Additionally, its wide range of available resistance values makes it perfect for customizing current flows for various applications. The series also offers excellent voltage-breakdown characteristics, helping to protect sensitive components from damage. It is rated for currents up to 100 Amps, and can easily be integrated into almost any power last environment.

Conclusion

The PFU1000-100KJ1 series of Chassis Mount Resistors is a reliable, efficient, and cost-effective solution for many current limiting and temperature controlling applications. Offering a wide range of resistance values and voltage-breakdown characteristics, it can easily be integrated into almost any power last environment. Its robust construction ensures uniform temperature distribution and high resistance stability over life, helping to protect sensitive components from damage.
