Chassis Mount Resistors

Chassis Mount Resistors, also known as trimmer resistors, are variable resistors that are used to control or adjust levels of frequency, voltage, current, or temperature. They are designed for installation in electronic devices and are typically mounted on a printed circuit board (PCB). The KAL250FB1R00 is a type of chassis mount resistor which is characterized by its small size, low height, and high-precision resistance. It is capable of withstanding harsh environmental conditions and can offer a wide range of resistance values.

KAL250FB1R00 Application Field

The KAL250FB1R00 adjustable resistor is a low-cost, thick-film resistor with a precision tolerance of 0.1%. It is designed for use in a variety of electronic applications including industrial computers, telecommunication systems, medical equipment, and consumer products. It offers high power dissipation and is capable of sustaining a temperature range of -55°C to 125°C. In addition, it provides excellent contact protection against external moisture and chemicals, making it suitable for long-term use in humid and dust-filled environments.

KAL250FB1R00 Working Principle

The KAL250FB1R00 adjustable resistor uses a thin-film resistive element combined with a thick-film resistive layer. This design helps to minimize lead impedance and reduce the influence of temperature changes. The resistor features a top-adjusting screw to provide accurate and stable control over its resistance value. The top of the resistor is made from a wide-range of materials such as aluminum, brass, phosphor bronze, stainless steel, and other non-magnetic metals. The screw has a height of only 1mm, which prevents it from interfering with the circuit’s other components. The KAL250FB1R00 adjustable resistor offers a low-profile, high-precision solution for controlling resistance values in a variety of electronic applications. It is designed with a precision tolerance of 0.1% and is highly resistant to changes in temperature and humidity. Its top-adjusting screw helps to ensure accurate and reliable adjustment of resistance values. In addition, the KAL250FB1R00 can withstand harsh environmental conditions and is suitable for long-term use in a variety of electronic applications.
