Chassis Mount Resistors: KAL50JBR120 Application Field and Working Principle

A chassis mount resistor is a resistive device that is designed to offer dynamic resistance to alternating currents (AC) or direct currents (DC) within a specified range. The device mounts on a section of the frame of the machine or system, and it is available in a wide range of shapes and sizes.The KAL50JBR120 is a chassis mount resistor manufactured by the Korean electronic components company Kalunder. Specifically, it is a cylindrical, axle-hole-style resistor that is designed to offer extremely precise resistive values when used with AC or DC output signals.

Design

The KAL50JBR120 is a cylindrical-style, axle-hole-style resilient device. It measures in at 50mm in length and 30 mm in diameter, is constructed from a combination of durable ABS plastic and dielectric epoxy resin, and features a sealed, moisture-resistant construction. In addition, the device is rated for operation in temperatures ranging from -55°C to +125°C.The KAL50JBR120 also features a resistance rating of 10 ohms, a tolerance of 1%, and a power rating of 1.5 watts. It is also available in a variety of colors, allowing users to easily select the appropriate color to match the application environment and any other associated devices.

Application Field

Given the design features of the KAL50JBR120, it is well-suited for use in a variety of applications, including automotive, industrial control, telecommunications systems, medical equipment, robotics, and audio/visual (AV) systems.In automotive applications, the KAL50JBR120 provides precise resistive values when used in speed control circuits, fan control circuits, air conditioning, and braking systems. It also helps protect other components from accidental, short-term current overload by effectively dissipating the excess energy.In industrial control applications, the KAL50JBR120 is useful when used with AC and DC voltage signals, as it is capable of providing highly accurate resistive values and excellent stability when connected in series with the device under test. Its extended operating temperature range also makes it suitable for use in outdoor, high-temperature environments.The KAL50JBR120 is also ideal for use with medical equipment. It is capable of offering precise resistance values within a wide operating temperature range of -55°C to +125°C, and it is highly stable and reliable over long periods of use.

Working Principle

The KAL50JBR120 is a passive device, meaning it does not require any external power source. Instead, it works by converting a portion of the input electrical signal into heat in order to stabilize the signal.Specifically, the device works by allowing some of the electrical current to pass through it, while the rest of the signal is diverted into a dissipative path, which converts it into an equivalent amount of heat. This helps to stabilize the signal by ensuring that current is flowing at a steady rate, preventing it from exceeding the designed maximum or minimum. This protects other components in the system and ensures that the application is running properly.

Conclusion

The KAL50JBR120 is a highly precise, durable chassis mount resistor. It is rated for operation in temperatures ranging from -55°C to +125°C and offers highly accurate resistive values when used with AC or DC output signals. It is well-suited for use in automotive, industrial control, telecommunications, medical equipment, and audio/visual applications and works by converting a portion of the input electrical signal into heat in order to stabilize the signal.
