What is a color ring resistor and how to correctly identify it? 1

Color ring resistor is an EM78P153SNJ resistor that uses color coding to indicate its resistance, tolerance, and sometimes temperature coefficient. This encoding method is convenient for quickly and intuitively identifying the characteristics of resistors, especially in situations where space is limited or it is not convenient to print numbers. Color ring resistors are usually represented by coating different colored rings on the insulator of the resistor to indicate different values.diode

The identification method of color ring resistors is usually based on standard color coding. The following are the steps on how to correctly identify color ring resistors:

1. Understand color coding:diode

Each color represents a specific number, and the following is a standard color code table:

Black: 0

● Brown: 1

● Red: 2

Orange: 3

● Yellow: 4

Green: 5

● Blue: 6

Purple (or Violet): 7

● Grey: 8

● White: 9diode
