SMD Resistor 100Kohm (104) (0805) (10pcs)

Description

SMD Resistor 100KΩ (104) OHM (0805) (10pcs)

The SMD Resistor 100KΩ (104) OHM (0805) is a surface-mount device (SMD) resistor with a resistance value of 100,000 ohms (100KΩ). It is designed in an 0805 package that allows it to fit in high-density circuit boards, ideal for compact and modern electronic designs. The resistor is typically provided in packs of 10 pieces, making it suitable for prototyping, repairs, or small-volume production.

Key Features:

1. Resistance Value:

   • 100KΩ (100,000 ohms).

   • The “104” code is the standard 3-digit code for this resistance value:

     • 10 represents the base value (10).

     • 4 is the multiplier (10⁴), so 10 × 10,000 = 100,000 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 widely used for its balance of compact size and easy handling, suitable for automated PCB placement.

3. Quantity:

   • Supplied in 10 pieces, perfect for small projects or quick repairs.

4. Tolerance:

   • Typically ±5%, though this may vary by manufacturer. This means the resistance can vary by up to 5% above or below the nominal value of 100KΩ.

5. Power Rating:

   • 0.125W (1/8 watt) for most 0805 resistors, which is appropriate for low-power applications. Be sure to verify the specific power rating based on your circuit needs.

6. Composition:

   • The resistor is usually made from materials like metal oxide, carbon film, or thick film, ensuring reliability and stable performance in a variety of environments.

Applications:

1. Voltage Dividers:

   • The 100KΩ resistor is ideal for voltage divider circuits, where it helps in creating precise voltage levels for biasing transistors or op-amps.

2. Signal Conditioning:

   • Used in signal conditioning circuits, including current-limiting, attenuation, and filtering of analog or digital signals.

3. Pull-up/Pull-down Resistors:

   • Commonly used in digital circuits as pull-up or pull-down resistors, ensuring a defined logic level when no active device is driving a signal.

4. LED Current Limiting:

   • Helps to limit the current flowing to an LED, protecting the LED from excessive current that could damage it.

5. Sensor Circuits:

   • Used in sensor circuits for biasing or conditioning sensors such as thermistors or photodiodes, especially in analog-to-digital conversion applications.

6. Signal Filtering:

   • Suitable for use in low-pass or high-pass filters to define the cutoff frequency for specific signal processing applications, including audio or RF circuits.

7. Impedance Matching:

   • In communication circuits, it can be used for impedance matching, ensuring efficient signal transfer between components.

Advantages:

• Compact Size (0805): The 0805 package is small and perfect for high-density designs, where space is limited.

• High Precision: Offers accurate resistance values for precise circuit behavior.

• Reliability: SMD resistors like the 100KΩ (104) are robust and durable, offering good performance even in harsh environments.

• Cost-Effective: These resistors are ideal for high-volume manufacturing due to their small size, ease of placement, and low cost.

• Low Inductance: With low inductance compared to through-hole resistors, these are ideal for high-frequency circuits.
