1. Application
YSE-R68 is an experimental resistor composed of multiple decimal switches connected in series. Each resistor element is connected between the contacts of the switch. The resistance between the two terminals can be changed by changing the electrical position of the switch to obtain various resistance values. It is suitable for schools, scientific research institutions, corporate R&D departments, etc. as a standard reference resistance value, precision adjustment of resistance in DC circuits, and instrument calibration.
