The SHT1-200C075DE has a high electrical isolation rating of up to 200kV, which makes it suitable for use in High Voltage circuits, such as HVAC equipment. Additionally, the device is RoHS compliant, and is UL recognized for safety applications.

The Working Principle of SHT1-200C075DE

The SHT1-200C075DE is a voltage-controlled, SMT resistor whose resistance is determined by the applied voltage. It consists of a resistor element and a voltage-sensing element. The resistor element consists of a carbon composition substrate and two resistive metal layers made from aluminum or nickel-chrome covered materials. The voltage sensing element is an oxide-filled gap in the metal layer, which determines the resistance of the resistor element at a given voltage.

When voltage is applied to the resistor, current passes through the resistor element which causes a voltage drop across the resistor. This voltage drop is then sensed by the voltage-sensing element, and the change in resistance is proportional to the applied voltage. The value of the resistor can be adjusted by either increasing or decreasing the applied voltage.

The SHT1-200C075DE is a temperature-coated differential element, meaning the device has good thermal stability and temperature compensation. It has a very low tolerances of ±1.2%, making it suitable for use in critical applications where precise resistance values are required. Due to its high power rating, the resistor is also suitable for use in high-current circuits.

The SHT1-200C075DE provides reliable performance under extreme conditions, such as high temperatures, shock, and vibration. The device is also highly reliable and provides excellent long-term stability. Additionally, the device is available in various shapes and sizes, including surface mount and axial-lead packages.

In conclusion, the SHT1-200C075DE is a high-power, temperature-coated chassis mount resistor, suitable for a variety of applications including high voltage circuits, medical devices, automotive, power supplies, and test equipment. The device has excellent power rating, temperature compensation, voltage-controlled resistance, and long-term stability.
