Product Information:

A resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element. Resistors act to reduce current flow, and, at the same time, act to lower voltage levels within circuits. In electronic circuits, resistors are used to limit current flow, to adjust signal levels, bias active elements, and terminate transmission lines among other uses.

220 Ω / 220 R / 220 E / 220 Ohm:

Features:

  • Resistance: 220Ω
  • Tolerance: 5%.
  • Power rating: 1/4Watt.

Applications:

  • Voltage limiter.
  • Current Limiter.
  • DIY projects requiring impedance matching.

Resistor Colour Code:

Value 220 Ω
Type 4 Band Colour Code System
Colour Code RedRedBrownGold
Multiplier Brown, 10
Tolerance Gold Band ±5%

 

Test With Digital Multimeter:

 

1) 220 Ohm Resistor color code:

Red, Red, Brown, Gold

Band Color Value
1st Red
2
2nd Red
2
3rd Brown
10
4th gold
+-5%
  1st digit 2
2nd digit 2
3rd multiplier: x10
220 Ohm
tolerance: +-5%

2) It is calculated as:

(link of calculating resistor by color code in detail)

1st band= Red= 2(1st digit)

2nd band= Red= 2(2nd digit)

3rd band= Brown= 10(multiplier)

4th band= Gold= ±5% (tolerance)

Therefore, 22×10±5%  ==> 220Ω  ==> 0.22kΩ

And tolerance considered as ==> 5%of220 ==>11Ω

Final assumed value of 220Ω resistor is between 209 to 231Ω

 

3) Resistor color code 220 Ohm 5% tolerance:

Red, Red, Brown, Silver

4) It is calculated as:

1st band= Red= 2(1st digit)

2nd band= Red= 2(2nd digit)

3rd band= Brown= 10(multiplier)

4th band= Gold= ±5% (tolerance)

Therefore, 22×10±10%  ==> 220Ω  ==> 0.22kΩ

And tolerance considered as ==> 5%of220 ==>22Ω

Final assumed value of 220Ω resistor is between 198 to 242Ω

5) Caution for 220 ohm resistor code:

If resistor contains Brown and Red color in bands then check it, because, red and brown appears to be very similar when it is placed in a circuit.

6) Other methods:

Use a DMM to take the value of resistor best method to do so. But digital multimeter does not read proper values when a resistor is on PCB or connected to other components, in such situation color code is reliable
