# How do you read a resistor code?

## How do you read a resistor code?

Always read resistors from left to right. – Resistors never start with a metallic band on the left. If you have a resistor with a gold or silver band on one end, you have a 5% or 10% tolerance resistor. Position the resistor with this band on the right side and again read your resistor from left to right.

## What J means in resistor?

G = +- 2% J = +- 5% K = +- 10% M = +- 20%

What is M in resistor?

Every 1,000,000 Ohms is known as a Megohm (Mega = one million), abbreviated to the capital letter “M”. As a couple of examples; a 4,700 Ohm resistor would be written as either 4.7K or 4K7, and 5,600,000 Ohms would be written as 5.6M or 5M6.

What EIA 96?

The EIA-96 System Therefore the EIA-96 marking system has been created. It is based on the E96-series, thus aimed at resistors with 1% tolerance. In this system, the marking exists out of three digits: 2 numbers to indicate the resistor value and 1 letter for the multiplier.

### What is a 4R7 resistor?

4R7 Resistor color code / 4.7 Ω (Ohms)

### How to identify resistor?

1/8 Watt Resistor – 1.8 x 3 x 28: It handles 13.88 mA when connected to 9 V source

• 1/4 Watt Resistor – 2.5 x 6.5 x 28: It handles 27.77 mA when connected to 9 V source
• 1/2 Watt Resistor – 3.2 x 8.5 x 28: It handles 55.55 mA when connected to 9 V source
• 1 Watt Resistor – 5 x 11 x 28: It handles 111.11 mA when connected to 9 V source
• How to decode a resistor?

Decide which band is the first band.

• Look up the color of the first band in the column labeled “1st digit” and find the number associated with that color.
• Look up the color of the second band in the column labeled “2nd digit” and find the number associated with that color.

RED: 2

• GREEN: 5
• BLUE: 6
• VIOLET: 7
• GREY: 8
• WHITE: 9. But this is not for all colors. From right to left the second color is multiplier.
• RED: 100
• GREEN: 100000
• BLUE: 1000000
• GOLD: 0.1

B = 0.1%

• C = 0.25%
• D = 0.5%
• F = 1%
• G = 2%
• J = 5%
• K = 10%
• M = 20%
