Chassis Mount Resistors – KAL50FB1K50 Application Field and Working Principle

Chassis mount resistors are electrically resistant components used for controlling and regulating electric current in varied and different electronic circuits. KAL50FB4K50 is one of such chassis mount resistors and its application field and working principle will be discussed in the following.

Application Field of KAL50FB4K50

KAL50FB4K50 is chiefly used in circuit boards of avionics-related equipment. The robust device ensures that circuit traces conveniently lead to the surface mount device within the circuit board without any difficulties, legging, and tip-off. The product similarly assigned section includes an inner shield which frequently allows for it to function as a heat sink, letting the resistor to be properly driven while being securely placed into a circuit board\'s circuit trace. The improved insulation scores higher than regular materials, making it ideal for the purpose of avoiding electromagnetic induction in the circuit board.The KAL50FB4K50 is applicable to all kinds of devices, from conventional fixed carrier boards to highly flexible products, like those replying to printed circuit boards. These built-in components are highly valued because of their excellent heat resistance and their matchless versatility with regards to customizable shape and functioning. KAL50FB4K50 is also found in some of the most challenging applications like high-speed systems, automotives, and handheld portable tools.

Working Principle of KAL50FB4K50

The basic structure of the product is composed of two major components: a metal plate and a ceramic substrate. The metal plate is connected to a power source for allowing current to flow, while the ceramic substrate is made of material like an alumina-based oxide ceramic that is composed of dielectric layers.The plate acts as an electrical contact point, while the substrate acts as an insulating barrier between the electrostatic charges and electro-magnetic field. This helps to establish a thermal barrier as the higher the temperature the higher the resistance. As the voltage applied to the plate increases, it increases the electric current resistant through the surface. The current, in turn, causes the temperature of the device to rise, thus effectively counteracting the voltage supplied and helping to regulate the voltage in the circuit.KAL50FB4K50 is also distinctive in design, being a surface mount resistor that offers low profile geometry and space-saving installation capabilities, available in standard and custom shapes. Its high thermal conductivity makes it suitable to withstand high temperatures in various applications.In conclusion, the KAL50FB4K50 is a sturdy chassis mount resistor that can be applied on avionics-related equipment. Its construction is made of a metal plate and a ceramic-based substrate, which together form a thermal barrier to reduce resistance and regulate voltage thus ensuring uninterrupted operation. It is available in varying shapes and designs, making it suitable for use in high-speed systems, automated machines, and portable electronic tools.
