Application Field

The RWR89S15R4FRS70 is an ultra-high power as well as a high-precision resistor that is suitable for use in a wide range of industries, such as power, energy, automotive, aerospace, and transport. It is widely used in applications that require extreme precision and high stability in voltage or current, such as in medical device applications. In addition, it is also suitable for high-end communications technologies, including Wi-Fi, Bluetooth, and UWB. Furthermore, its high-power rating of up to 200W makes it suitable for use in larger applications such as high-power motor drives.

Working Principle

The RWR89S15R4FRS70 is a four-terminal resistor with its working principle being based on the interaction of magnetic fields. It uses four terminals called the main power, heater, sense, and secondary heater terminals. The main power terminal is where the electrical power is supplied, and then the heater terminal is the voltage source used to maintain the resistor’s temperature. Through the sense terminal, the current and voltage are sensed and applied to the secondary heater terminal to control the power dissipated by the resistor. This combination of terminals allows the RWR89S15R4FRS70 to achieve an extremely high-precision level.

Conclusion

The RWR89S15R4FRS70 is a reliable and durable through-hole resistor that can be used in a wide range of applications. Its high-power rating, high-stability, and low-noise features make it the ideal choice for applications that require extreme precision. This article has explained the application field and the working principle of this resistor.
