Product Information

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. All color-coded resistors (regardless of how many bands they have) have at least two digit bands, one multiplier band, and one tolerance. This is the structure of a four band resistor color code; five and six band resistors add to this basic structure.

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. 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. The fourth band indicates the tolerance values. A Gold band is used in this example, 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.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. resistor: Used for LED, so within 1-2 kohm range, any resistor could be used. Only brightness intensity would decrease.

A 1/4-watt power rating is a common specification for resistors used in low-power electronic circuits. It indicates that the resistor can safely handle up to 0.25 watts of power without experiencing significant temperature rise. It is important to ensure that the power dissipated in the resistor remains within this specified limit to avoid thermal damage or deviation from the resistor's performance characteristics. 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.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. 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.

resistors are used for 3.3V supply protection. Higher value may not be recommended as they would be limiting the current required. Slightly smaller value than specified could be used but should not go beyond 10%. 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). 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. 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. 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).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. 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.

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. The 2200-ohm resistor is commonly represented using the numerical value of 2200 ohms or as 2.2k (kilo-ohms). It is a standard resistor value that is widely available in electronic component stores.

Please note:

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. 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. 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.
