SMD Resistor 22Kohm (223) (0805) (10pcs)

Description

SMD Resistor 22KΩ (223) OHM (0805) (10pcs)

The SMD Resistor 22KΩ (223) OHM (0805) is a surface-mount device (SMD) resistor with a resistance value of 22,000 ohms (22KΩ). It is designed in the 0805 package size, which is a standard size for compact electronic components. These resistors are typically sold in packs of 10 pieces, making them ideal for small projects, repairs, or prototyping.

Key Features:

1. Resistance Value:

   • 22KΩ (22,000 ohms).

   • The “223” code follows the 3-digit resistor code:

     • 22 represents the base value (22).

     • 3 is the multiplier (10³), making the resistance value 22 × 10³ = 22,000Ω.

2. Package Size:

   • 0805: The dimensions of the 0805 package are 0.08″ x 0.05″ (2.0mm x 1.25mm). This size is perfect for modern, compact, and high-density PCBs where space is a concern.

3. Quantity:

   • Supplied in packs of 10 pieces, which is ideal for small batches, repairs, or prototyping.

4. Tolerance:

   • Typically ±5%. This means that the actual resistance can vary by up to 5% from the nominal value. For higher precision, manufacturers might offer ±1% tolerance.

5. Power Rating:

   • 0.125W (1/8 watt). This is the standard power rating for 0805 resistors. Ensure that the resistor’s power rating is appropriate for your specific application to avoid overheating.

6. Composition:

   • Made from metal oxide, carbon film, or thick film, ensuring good stability and reliable performance over time.

Applications:

1. Voltage Dividers:

   • 22KΩ resistors are commonly used in voltage divider circuits, helping create specific voltage levels that are used for biasing transistors, op-amps, and other analog or digital components.

2. Current Limiting:

   • It can be used to limit current in circuits, such as in LED circuits or sensor protection circuits, preventing excess current from damaging sensitive components.

3. Pull-up/Pull-down Resistors:

   • In digital circuits, the 22KΩ resistor is often used as a pull-up or pull-down resistor to ensure the state of a signal line when no active device is driving it.

4. Signal Conditioning:

   • Used in signal conditioning circuits to filter, attenuate, or adjust signals, often in analog-to-digital conversion applications.

5. Filter Circuits:

   • It can be used in RC (Resistor-Capacitor) or RLC (Resistor-Inductor-Capacitor) filters, where the 22KΩ resistor sets the cutoff frequency and controls the frequency response in both audio and radio-frequency circuits.

6. Biasing and Amplification:

   • The 22KΩ resistor is used in biasing circuits for amplifiers or transistors, providing a stable operating point for linear components.

Advantages:

• Compact Size (0805): The 0805 size ensures that the resistor is small and can fit into tight spaces, which is ideal for high-density PCBs.

• Cost-Effective: SMD resistors are affordable and easy to handle in mass production, making them cost-effective for both prototyping and manufacturing.

• Reliability: SMD resistors offer consistent performance over time and are less prone to damage compared to through-hole resistors, especially in automated assembly environments.

• Precision: SMD resistors like the 22KΩ have stable resistance values, ensuring reliable circuit behavior.
