Chassis Mount Resistors: TE500B3R9J Application Field and Working Principle

Chassis mount resistors, also known as chassis mount resistors or chassis mount artards, are specialized type of resistors. They are like general resistors, but they are specifically suited for use in the confines of a connector or buildingstructures, where it is necessary to reduce space taken up by the resistor or its related wiring. TE500B3R9J is a type of chassis mount resistor. This article explores the application scope and working principle of TE500B3R9J. TE500B3R9J are non-inductive high power surface mount resistors. They are typically used in applications such as automotive, industrial, and commercial, including motor controller, forklift, agricultural machinery, military, aerospace, medical, security, and communication systems etc. TE500B3R9J resistors offer high power dissipation capability (PTC; PxT Clamp) when compared to traditional chip resistors. TE500B3R9J also have superior stability due to its construct shape and design, and have a wide working voltage range, offering high reliability that resistors should have in such critical applications.Therefore, this type of resistors offers a good choice for volume production with their extremely low internal resistance, high accuracy and stability. Furthermore, the non-inductive types are preferred for applications where high-frequency ripple currents are present. This is because they reduce phase shifting and EMI noise.The working principle of TE500B3R9J resistors is based on the material thermistor: thermistor has characteristics that the electrical resistance changes along with the temperature or temperature changes. TE500B3R9J utilizes this property by using three pieces of copper, heat dissipation plate, heating resistance plate and temperature sensitive material. When the components are exposed to voltage, the heating resistance plate will generate heat aaccording to the voltage, and then the heat will be passed on to the temperature sensitive material, thus inducing current to flow. When the voltage is lowered, the heat will dissipate to the heat dissipation substrate, leading to decreasing the temperature of the temperature sensitive material and the electrical resistance dropping back to the original value. Moreover, TE500B3R9J boasts multiple advantages, such as high power dissipation capability, high accuracy traceability, fast response time and so on. They are optimal for applications with high power loads, like power switching/protection circuits, gate control, motor control, high power charge and discharge circuits, as well as winding/unwinding motor applications.To sum up, TE500B3R9J are chassis mount resistors with application scope in automotive, industrial and commercial systems. They are known for high power dissipation capability and superior stability. Furthermore, they offer fast response time and high accuracy traceability. With the advantages described above, TE500B3R9J are the superior choice in high power load applications.
