Understanding the Value of a 5-Band Resistor: A Comprehensive Guide

When dealing with electrical components, understanding the value of resistors is a fundamental skill. In the case of a 5-band resistor, deciphering its color code can seem challenging, but it's actually quite straightforward once you understand the pattern.

Color Code Chart for 5-Band Resistors

The color code for a 5-band resistor uses five bands of color to indicate the resistance value, tolerance, and sometimes the multiplier. Here's a common color code chart:

Color Value Yellow 4 Black 0 Red 2 Brown 1

Deciphering the 5-Band Resistor: Yellow Black Red Black Brown

Let's take a closer look at a specific 5-band resistor: one with the color bands yellow, black, red, black, and brown. Here's how you can interpret its value:

First Three Digits (Yellow, Black, Red): Start with the first three bands. Yellow (4), Black (0), and Red (2) represent the first three significant digits. Therefore, the first part of the value is 402. Multiplicand (Black): The fourth band, which is again black, indicates that there is no multiplication factor (1). Tolerance (Brown): The fifth band, brown, represents the tolerance of the resistor, which is 1%.

Putting it all together, the resistor has a value of 402 ohms with a tolerance of 1%. This means the actual resistance likely lies within a range of 401.62 ohms to 402.38 ohms (402 ohms ± 1%).

Understanding Odd Resistor Values

While the value of 402 ohms may seem unusual, it is a valid reading. If you are unsure about the color bands or suspect a mistake, double-check the colors and the chart. Sometimes, manufacturers use non-standard band arrangements or use the resistor's color code to indicate other parameters.

Conclusion

Understanding the color code of a 5-band resistor is crucial for any electronics enthusiast or professional. By following the chart and rules we've outlined, you can easily decode any 5-band resistor and ensure that you're working with the correct electrical components.
