Product Information

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. Amplifier Biasing: In amplifier circuits, the 2.2k ohm resistor is employed in biasing networks. It helps establish the required bias voltage levels for proper transistor or operational amplifier operation, ensuring stable and accurate amplification. 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). By incorporating a 2200-ohm resistor into a circuit, engineers and designers can precisely control the behavior of the circuit, ensuring safe and efficient operation. Creating a precise 2.2k ohm resistor from scratch is a complex and specialized process that often requires advanced manufacturing techniques and equipment. It involves careful control of resistor material, size, and other factors to achieve the desired resistance value. So making your own 2.2k ohm resistor is not practical for most people.

A 2200-ohm resistor is an electrical component that is used to impede the flow of electric current in a circuit. It is designed to offer a resistance of 2200 ohms, which means that it restricts the amount of current that can pass through it. Resistors are passive components that dissipate electrical energy in the form of heat when current flows through them. resistor: As they are behaving for pull-up functions, could be used in the range of 10-12 kohm, it will not impact your circuit. A 2.2k ohm 1/4-watt resistor refers to a resistor with a resistance value of 2.2 kilo-ohms (2200 ohms) and a power rating of 1/4 watt. The power rating specifies the maximum power the resistor can dissipate without overheating or getting damaged. Resistor color codes consist of digits followed by a multiplier and a tolerance value. Four band resistors have two bands for digits, while five band resistors have three bands for digits. Six band resistors also add a temperature coefficient. 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.In the realm of electronics, resistors play a vital role in controlling and regulating the flow of electric current. Among the diverse range of resistors available, the 2200-ohm resistor, commonly represented as 2.2k, holds significance. This article aims to explore the definition of the 2200-ohm resistor, decipher its color code, and shed light on its various applications in electronic circuits. By unraveling the intricacies of this essential component, we can deepen our understanding of its functionality and unleash its potential in electrical engineering. Yes, there are specialized variants of the 2200-ohm resistor available to meet specific application requirements. For example, precision resistors with tighter tolerance values (e.g., 1% or 0.1%) may be used in applications where precise resistance values are crucial. Additionally, temperature-compensated resistors or high-temperature resistors may be used in environments with extreme temperature conditions to maintain stable resistance values.

Start by identifying the last band first. On four and five band resistors, the last band is usually gold or silver and should be separated from the other bands by a small gap. This band gives us the tolerance of the 2.2k Ohm resistor. On six band resistors, the last two bands should be tightly grouped, and the first four bands should be tightly grouped. There should be a noticeable gap between the fourth and fifth band.A 2.2k ohm 1-watt resistor refers to a resistor with a resistance value of 2.2 kilo-ohms (2200 ohms) and a power rating of 1 watt. The power rating indicates the maximum power that the resistor can safely dissipate without overheating or getting damaged. 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. Voltage Dividers: In voltage divider circuits, the 2.2k ohm resistor is often used in conjunction with other resistors to create a specific output voltage. By strategically placing the 2.2k ohm resistor in the divider network, it helps in dividing the input voltage and generating the desired output voltage. Resistors are essential in electronic circuits for various purposes. They can be used to limit current flow, divide voltages, and provide load resistance, among other applications. The 2200-ohm resistor is often used in circuit designs where a specific resistance value is required to achieve the desired electrical characteristics or to protect components from excessive current. 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.

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. They are read exactly the same way as five band resistors, except that the (additional) last band tells us the temperature coefficient. Color Four band resistors have two bands for the value, one for the multiplier, and one for the tolerance.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. 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. As a result, the resistance value of the resistor with the color bands of Red Red Gold Gold is 2.2 Ohm with ±5% tolerance. Recomendation Analog-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). 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%.

The gold band indicates the tolerance level, which specifies the acceptable range of the resistor's actual resistance value. The fourth band indicates the tolerance values. A Gold band is used in this example, giving us a tolerance of 5%. 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. 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). 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.

These features collectively contribute to the functionality and reliability of the 2.2k ohm resistor, making it suitable for a wide range of applications in electronic circuits, such as voltage dividers, current-limiting circuits, signal conditioning, and many other circuit designs that require precise resistance values. 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.
