Hnstshop Mall introduces the identification method of color ring resistors. Color ring resistors are the earliest and most traditional resistors widely used in various power supplies and controllers. Because the color ring resistance is different from the chip resistance, with only the color ring on the surface and no other resistance values printed on the screen, the color ring resistance is mainly recognized through the color ring.

The resistance value of the five ring resistor can be identified through the following steps:
1. Observe the color coding of the resistor: A five ring resistor is usually composed of five colored bands. Each band represents a number or multiplier, with the first band, second band, third band, fourth band, and fifth band from left to right.
2. Determine the color of the first band: The first band represents the first digit of the resistance. You can use a resistance value and color comparison table to determine the corresponding number.
3. Determine the color of the second band: The second band represents the second digit of the resistance. Similarly, use a comparison table to determine the corresponding numbers.
4. Determine the color of the third band: The third band represents the multiplier of the resistance. The multiplier determines the order of magnitude of the resistance value. A comparison table can help you determine the multiplier.
5. Determine the color of the fourth band (optional): The fourth band is usually silver or gold, indicating the tolerance of resistance. Silver represents a tolerance of ± 10%, while gold represents a tolerance of ± 5%. If there is no fourth band, the tolerance is ± 20%.
6. Determine the color of the fifth band (optional): The fifth band is usually silver or gold, representing the temperature coefficient of resistance. Silver represents a temperature coefficient of ± 100ppm/° C, while gold represents a temperature coefficient of ± 50ppm/° C. If there is no fifth band, it means that the temperature coefficient is zero.
Through the above steps, you can identify the resistance value of the five ring resistor based on its color coding. Please note that this is a common method, but in practical operation, it is important to ensure that the correct comparison table and accurate color recognition are used.
