Product Information

Band One – 1 st Digit: The first digit of the resistance value. The first band on a 2.2k ohm resistor is red, which corresponds to a value of 2. One difficulty is that the 2.2k ohm resistor is easy to confuse with a 220 ohm resistor, so keep this in mind and verify using the color code or a multimeter if possible. Therefore, a 2.2k-ohm resistor with this color code would have a resistance value of 2200 ohms or 2.2 kilo-ohms, with a tolerance of 5% (gold band). As a result, the resistance value of the resistor with the color bands of Red Red Red Gold is 2.2k Ohm with ±5% tolerance. Recomendation

If the fourth band is silver, the tolerance is 10% and the total resistance is 2.2kΩ ± 10% Ω. The actual resistance will be between 1980 Ω (2.2k Ω – 220 Ω) and 2420 Ω (2.2k Ω + 220 Ω). They are read exactly the same way as five band resistors, except that the (additional) last band tells us the temperature coefficient. ColorAnalog-to-Digital Conversion: The 2.2k ohm resistor can be used in voltage divider networks as part of analog-to-digital conversion circuits. It helps in scaling down the input voltage range to match the operating range of an analog-to-digital converter (ADC). For the most accurate and up-to-date pricing information, it is recommended to consult an electronic component supplier or an online retailer that specializes in resistors. They will provide you with specific pricing based on your requirements and current market conditions. Current Limiting: The 2.2k ohm resistor is frequently employed as a current-limiting resistor. By connecting it in series with an LED or other components, it restricts the flow of current to a safe and desired level, preventing damage to the components. The third band is the multiplier. Multiply the value designated by the first two bands with the multiplier to find the full value of the resistor. Band Three – Multiplier: Takes the digits and multiplies them by a value given by this band. The actual multiplier is 10 n, where n is a value that corresponds to the color of the band. In this case, the third band is red, which corresponds to the number 2. Therefore the multiplier is 10 2 = 100.

Company policy is that we do not under any circumstances issue instructions to our couriers to leave deliveries unattended when no one is at the delivery location. Band Four – Tolerance: Gives the value of the tolerance for the resistor. The most common values are 5% (designated by a gold band), and 10% (designated by a silver band). This example uses a gold band, giving us a tolerance of 5%.To produce resistors with consistent resistance values such as 2.2k ohms requires a highly controlled manufacturing process in specialized facilities. These processes involve precision equipment and techniques such as thin film deposition, laser trimming and quality control testing to ensure resistors meet specified resistance tolerances and performance standards. Four band resistors have two bands for the value, one for the multiplier, and one for the tolerance. The color of the first band indicates the value of the first significant digit. The first band is Red, which corresponds to the value 2. A 1-watt power rating signifies that this resistor can handle up to 1 watt of power without experiencing significant temperature rise. This higher power rating makes it suitable for applications where higher power levels are involved, such as in power supply circuits, amplifiers, or circuits that require significant current flow.

In a six band resistor, the last two bands (i.e. the fifth and sixth bands) should be closely spaced, with a gap between the fourth and fifth bands. Band Two – 2 nd Digit: The second digit of the resistance value. This band is also red, which again corresponds to the value 2. This is added to the right of the first digit (from band one). The voltage limitations of a 2200-ohm resistor depend on factors such as its power rating and construction. Typically, a 1/4-watt 2200-ohm resistor can handle voltages within the range of a few volts to tens of volts, while a 1-watt 2200-ohm resistor can withstand higher voltages, potentially up to a few hundred volts. It is important to consider the power rating and voltage requirements of your specific application when selecting a resistor. Resistance must be measured with the power off so ensure that the circuit is disconnected and that all energy storing devices (batteries, capacitors) are disconnected or discharged. 4-Band vs. 5-Band vs. 6-Band 2.2k Ohm Resistor Color Code Signal Conditioning: The 2.2k ohm resistor is used in signal conditioning circuits to modify or adapt signals to suit the requirements of subsequent circuitry. It can be part of filter networks, attenuators, or voltage dividers to condition signals for optimal processing.

New Passive Components

The color code for a 2.2k-ohm resistor typically consists of four color bands. Each color represents a specific numerical value or multiplier. The standard color code for a 2.2k-ohm resistor is: The third color band represents a decimal multiplier by which the first two digits must be multiplied to obtain the resistance value of the resistor. Takes the digits and multiplies them by a value given by this band. The actual multiplier is 10 n, where n is the value of the band color. In this case, the third band is Gold which corresponds to the number -1. Therefore the multiplier is 10 -1 = 0.1. For most practical purposes, it is more feasible and reliable to obtain commercially manufactured 2.2k ohm resistors from electronic component suppliers. These resistors are readily available, affordable, and manufactured under controlled conditions that ensure their accuracy and performance.
