Chassis Mount Resistors includes many different types of resistors, each with its own unique set of features and capabilities. One of the most commonly used resistors in this category is the KAL25FB250R. This resistor is well-suited to several electronic applications, and it has some unique characteristics that make it ideal for a range of purposes. In this article, we will explore the application field and working principle of the KAL25FB250R.

Application Field of KAL25FB250R

The KAL25FB250R is a popular choice for many applications. It is used in a variety of systems, including automotive, medical, and industrial applications. Some of the most common uses of these resistors are in motor assemblies, power converters, noise filters, high-frequency switching filters, and pre-charge circuits. The KAL25FB250R can also be used in automotive applications, such as airbag systems, fuel injectors, and ECUs. In addition, the KAL25FB250R has been used in high-frequency power supplies, conditioners for audio and video applications, and LED drivers.

Some of the advantages of using these resistors are their high reliability, long-term stability, and RoHS compliance. Furthermore, the KAL25FB250R features a high-voltage capability (up to 750V) and a low inductance (down to 0.4 nH). This feature makes it well-suited for high-frequency applications such as RF amplifiers, filters, and oscillators.

Working Principle of KAL25FB250R

The KAL25FB250R is a high-quality chassis mount resistor, meaning that it is designed to be mounted on the chassis of an electronic device. This type of resistor is often used as a surge protection component, since it can safely dissipate excess current without damaging the rest of the circuit. The working principle of the KAL25FB250R is relatively simple. It is made up of two main components, the resistor element and the mounting foot. The resistor element is the main active part of the resistor, and it is responsible for dissipating the energy that is generated by the current passing through the resistor.

The resistor element is composed of a semi-conductive material that has a predetermined resistance value. This resistance value is determined by the type and size of the resistor element, and it is usually printed on the component itself. When current flows through the resistor element, it generates heat, which is dissipated by the mounting foot. The mounting foot is an insulating casing that physically attaches the KAL25FB250R to the chassis. It also serves as an additional means of dissipating heat.

The KAL25FB250R also has an additional feature known as a shorting loop. This loop allows the resistor to protect itself in the event of a failure. If the resistor element is overloaded, the current is diverted through the shorting loop, which prevents the resistor from being damaged.

Conclusion

The KAL25FB250R is a highly reliable and versatile chassis mount resistor. It is used in a variety of applications, including automotive, medical, and industrial. The resistor element dissipates the energy generated by the current, and the mounting foot attaches the resistor to the chassis. The KAL25FB250R also has an additional shorting loop, which helps to protect the resistor from overloading. In summary, the KAL25FB250R is a reliable, durable, and RoHS compliant chassis mount resistor that is well-suited to many applications.
