The working principle of the RL20S621GRSL through-hole resistor is based on the Joule heating effect. This effect causes heat to be generated inside the resistor, thus increasing its resistance value. As the temperature inside the resistor increases, the resistance of the resistor also increases, eventually reaching a steady-state or thermal equilibrium. The temperature of the resistor is then maintained at a constant level, and the resistance value remains constant. The resistance value is not affected by thermal shock or mechanical shock, making this type of resistor very reliable for applications where high precision is required.

In addition to its high reliability, the RL20S621GRSL through-hole resistor also has a number of other features that make it suitable for use in challenging applications. For example, the resistor has a temperature coefficient of 0.05%, which is suitable for temperature control applications. Additionally, the peak pulse power rating of the resistor is 2 Watts, and it is available in a wide range of resistance values to meet the specific requirements of various applications. The integrated self-heating system of this resistor also ensures that the resistor remains at a constant temperature.

In conclusion, the RL20S621GRSL through-hole resistor is a highly reliable and cost-effective resistor that can be used in a wide variety of applications. Its resistance values are adjustable, ensuring that it is suitable for many applications that require precision.
