RLR20C7R50GRR36

Through hole resistors are non-discrete electronic components used to control the current flow in a circuit. They help to prevent excessive current from damaging components, and can also be used for voltage division and other applications. The RLR20C7R50GRR36 is one type of through-hole resistors, often used for high voltage and power applications. In this article, we will discuss its application field and working principle.

Application Field

The RLR20C7R50GRR36 is designed for high voltage and power applications. This type of resistor is made from a special material that can withstand voltages up to 1.4kV. It has an operating temperature range of -55°C to +125°C, and is able to dissipate power up to 400W at 25°C. It can be used in various applications, such as lighting, telecom, power supply, and medical device components. The RLR20C7R50GRR36 is also UL Recognized, cUL Recognized, and RoHS Compliant.

Working Principle

The RLR20C7R50GRR36 is an NTC (Negative Temperature Coefficient) resistor. This means that the resistance of the component increases as the temperature decreases. This allows the resistor to regulate the current flow in a circuit, preventing excessive current from damaging the components. As the temperature increases, the resistance drops, allowing more current to flow. The resistance of the RLR20C7R50GRR36 can be adjusted by changing the voltage applied to the element.

The RLR20C7R50GRR36 is also designed to dissipate heat effectively. This is done by using a heat sink, or a special mounting plate that dissipates the heat from the component. The heat generated by the resistor is conducted away by the heat sink, preventing the component from overheating.
