Product Information

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. All resistors have a tolerance value, which means that the value is unlikely to be exactly 2.2k Ohms. Higher quality resistors have tighter tolerances. 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. 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. 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.

Four band resistors have two bands for the value, one for the multiplier, and one for the tolerance. 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.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. 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 color of the second band indicates the value of the second significant digit. This band is Red, which corresponds to the value 2. This is added to the right of the first digit (from band one). Therefore the digits from band one and band two are: 22. Five percent of 2.2k Ω is 110 Ω. This means that the actual resistance value could be anywhere from 2090 Ω (2.2k Ω – 110 Ω) to 2310 Ω (2.2k Ω + 110 Ω). Six band resistors add another color band at the end of the resistor that tells us the temperature coefficient. This is an indication of how sensitive the resistor is to temperature changes.In a five band resistor, the first four bands tell us the nominal value of the resistor. Note that a five band resistor’s extra band is used to add a digit to the nominal value. You can think of it as an extra digit band at the front, with the other bands retaining the same function as those of a four band resistor. The fifth band identifies the tolerance. They are read exactly the same way as five band resistors, except that the (additional) last band tells us the temperature coefficient. Color It is important to note that prices fluctuate over time due to factors such as supply and demand, market conditions, and specific suppliers. Also, buying in bulk or from a wholesaler may offer a discounted price compared to buying individual resistors. 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.

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. It is important to select a resistor with a power rating that matches or exceeds the power requirements of the circuit to ensure reliable operation. Using a resistor with a power rating lower than what the circuit demands may result in overheating, potential failure, or alteration of its resistance value.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. 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 Red which corresponds to the number 2. Therefore the multiplier is 10 2 = 100.

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. 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. 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.You can use a multimeter to measure the resistance, but note that it will also vary with temperature. Resistors dissipate energy as heat, so temperature is an important consideration. In 6 band resistors, the temperature dependence is given by the last band (more on this below). 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. Pull-up and Pull-down Resistors: In digital circuits, the 2.2k ohm resistor acts as a pull-up or pull-down resistor. It ensures that inputs to digital devices have a stable voltage level when they are not actively driven by other components, thereby preventing floating inputs.
