SMD Resistor 33KΩ (333) OHM (0805) (10pcs)

The SMD Resistor 33KΩ (333) OHM (0805) is a surface-mount device (SMD) resistor with a resistance value of 33,000 ohms (33KΩ). It is housed in an 0805 package, making it suitable for compact and high-density circuit designs. This resistor is typically supplied in packs of 10 pieces, making it ideal for prototyping or small-volume production.

Key Features:

1. Resistance Value:
   • 33KΩ (33,000 ohms).
   • The “333” code is the standard 3-digit code for this resistance value:
     • 33 represents the base value (33).
     • 3 is the multiplier (10³), so 33 × 1,000 = 33,000 ohms.
2. Package Size:
   • 0805 size: The dimensions of the package are 0.08″ x 0.05″ (2.0mm x 1.25mm). The 0805 package is one of the most common sizes used in modern electronics for high-density applications, allowing for a good balance between size and ease of handling.
3. Quantity:
   • Supplied in 10 pieces, suitable for small projects, repairs, or prototyping.
4. Tolerance:
   • Typically ±5%, although it may vary depending on the manufacturer. This tolerance indicates the possible deviation from the nominal resistance of 33KΩ.
5. Power Rating:
   • Usually 0.125W (1/8 watt) for 0805 size resistors. However, check the datasheet for specific details, as the power rating should align with your circuit’s requirements to avoid overheating.
6. Composition:
   • Made from materials like metal oxide, carbon film, or thick film, providing good stability and reliability across a variety of applications.

Applications:

1. Voltage Dividers:
   • Commonly used in voltage divider circuits to set precise voltage levels for transistor biasing, op-amp circuits, or other analog components.
2. Signal Conditioning:
   • Used in signal conditioning applications, such as current limiting, attenuation, and filtering in both analog and digital circuits.
3. Pull-up/Pull-down Resistors:
   • Essential in digital circuits to maintain the defined logic level (high or low) when no active driver is present. This is crucial in applications like logic gates and microcontroller input pins.
4. LED Current Limiting:
   • This resistor is often used to limit the current going to LEDs, preventing them from burning out by ensuring that only the appropriate amount of current flows through them.
5. Sensor Circuits:
   • Can be used in sensor circuits for biasing or conditioning the output of sensors such as thermistors or photodiodes, particularly in analog-to-digital conversion.
6. Signal Filtering:
   • Used in filter circuits like low-pass or high-pass filters to define cutoff frequencies for audio or RF circuits.
7. Impedance Matching:
   • In communication circuits, it is used for impedance matching to ensure maximum signal transfer between components.

Advantages:

• Compact Size (0805): The 0805 package is small enough to fit into high-density designs while still offering sufficient handling capability for automated placement.
• High Precision: These SMD resistors are highly accurate and stable, making them ideal for precise applications.
• Reliability: SMD resistors are less prone to mechanical damage compared to traditional through-hole resistors.
• Cost-Effective: Because of their small size and suitability for automated manufacturing processes, these resistors are cost-effective for mass production.
• Low Inductance: With low inductance, they are ideal for high-frequency applications where signal distortion needs to be minimized.
