Resistor Color Code Chart: A Comprehensive Guide to 100k Ohm Resistors
Introduction
Resistors are a crucial component in electronic circuits, and understanding their color code is essential for building and repairing electronic devices. In this article, we will focus on the 100k ohm resistor color code chart, which is a common value used in many electronic applications.
Resistor Color Code Chart
A resistor color code chart is a table that shows the corresponding colors for each digit of the resistor's value. The chart consists of five columns, each representing a digit in the resistor's value.
Band 1: First Digit
The first band represents the first digit of the resistor's value. The colors and their corresponding digits are:
| Color | Digit |
|---|---|
| Black | 0 |
| Brown | 1 |
| Red | 2 |
| Orange | 3 |
| Yellow | 4 |
| Green | 5 |
| Blue | 6 |
| Violet | 7 |
| Grey | 8 |
| White | 9 |
Band 2: Second Digit
The second band represents the second digit of the resistor's value. The colors and their corresponding digits are the same as the first band.
Band 3: Multiplier
The third band represents the multiplier, which is the power of 10 by which the first two digits should be multiplied. The colors and their corresponding multipliers are:
| Color | Multiplier |
|---|---|
| Black | 1 |
| Brown | 10 |
| Red | 100 |
| Orange | 1000 |
| Yellow | 10,000 |
| Green | 100,000 |
| Blue | 1,000,000 |
| Violet | 10,000,000 |
| Grey | 100,000,000 |
| Gold | 0.1 |
| Silver | 0.01 |
Band 4: Tolerance
The fourth band represents the tolerance, which is the percentage of error allowed in the resistor's value. The colors and their corresponding tolerances are:
| Color | Tolerance |
|---|---|
| Brown | ±1% |
| Red | ±2% |
| Green | ±0.5% |
| Blue | ±0.25% |
| Violet | ±0.1% |
| Grey | ±0.05% |
| Gold | ±5% |
| Silver | ±10% |
Band 5: Temperature Coefficient
The fifth band represents the temperature coefficient, which is the change in resistance per degree Celsius. The colors and their corresponding temperature coefficients are:
| Color | Temperature Coefficient |
|---|---|
| Brown | 100 ppm/K |
| Red | 50 ppm/K |
| Orange | 15 ppm/K |
| Yellow | 25 ppm/K |
| Green | 20 ppm/K |
| Blue | 10 ppm/K |
| Violet | 5 ppm/K |
100k Ohm Resistor Color Code Chart
Using the resistor color code chart, we can determine the color code for a 100k ohm resistor:
| Band | Color | Value |
|---|---|---|
| 1 | Brown | 1 |
| 2 | Black | 0 |
| 3 | Red | 100 |
| 4 | Gold | ±5% |
| 5 | Brown | 100 ppm/K |
The color code for a 100k ohm resistor is therefore: Brown-Black-Red-Gold-Brown.
Conclusion
Understanding the resistor color code chart is essential for building and repairing electronic devices. By using the chart, you can easily determine the value of a resistor, including the 100k ohm resistor, and ensure that your electronic projects are accurate and reliable.
