SMD Resistor 100ohm (101) (0805) (10pcs)

Description

SMD Resistor 100Ω (101) OHM (0805) (10pcs)

The SMD Resistor 100Ω (101) OHM (0805) is a surface-mount device (SMD) resistor with a resistance value of 100 ohms (100Ω). It comes in the 0805 package size, making it compact and suitable for use in high-density printed circuit boards (PCBs). This resistor is typically supplied in packs of 10 pieces, making it ideal for small projects, repairs, or prototyping.

Key Features:

1. Resistance Value:

   • 100Ω (100 ohms).

   • The “101” code follows the 3-digit resistor code:

     • 10 represents the base value (10).

     • 1 is the multiplier (10¹), so the resistance value is 10 × 10¹ = 100Ω.

2. Package Size:

   • 0805: The 0805 package dimensions are 0.08″ x 0.05″ (2.0mm x 1.25mm). The 0805 package is ideal for modern, compact PCB designs with limited space for components.

3. Quantity:

   • Supplied in packs of 10 pieces, making it convenient for small-scale applications, repairs, and prototyping.

4. Tolerance:

   • Typically ±5%, meaning the actual resistance value can vary by up to 5% from the nominal value. Higher precision resistors with ±1% tolerance are also available depending on the manufacturer.

5. Power Rating:

   • 0.125W (1/8 watt) is the standard power rating for 0805 resistors. It is suitable for low-power applications, but ensure the resistor’s power rating matches your circuit’s requirements.

6. Composition:

   • Made from metal oxide, carbon film, or thick film materials, which provide stable performance, durability, and reliability in a variety of electronic applications.

Applications:

1. Current Limiting:

   • The 100Ω resistor is commonly used for current-limiting applications, such as limiting current in LED circuits or sensor circuits, to prevent damage to components by controlling excessive current flow.

2. Voltage Dividers:

   • Used in voltage divider circuits to set specific voltage levels, useful for biasing components like transistors or op-amps, or for analog signal conditioning.

3. Signal Conditioning:

   • Can be used for signal conditioning, including applications that require impedance matching, voltage attenuation, or current sensing in both analog and digital circuits.

4. Pull-up/Pull-down Resistors:

   • The 100Ω resistor is commonly used in digital circuits as a pull-up or pull-down resistor to ensure the state of a signal line is defined when no active device is driving it.

5. Filtering:

   • In combination with capacitors or inductors, this resistor can be part of RC (Resistor-Capacitor) or RLC (Resistor-Inductor-Capacitor) filters, helping to define the cutoff frequency for low-pass, high-pass, or band-pass filters.

6. Biasing and Amplification:

   • The 100Ω resistor can be used in biasing circuits for transistors or amplifiers, ensuring stable operation and setting the appropriate operating point for these components.

Advantages:

• Compact Size (0805): The 0805 package is small and space-efficient, making it suitable for high-density PCBs in modern electronics.

• Cost-Effective: SMD resistors are inexpensive and easy to produce in large quantities, making them cost-effective for both prototyping and mass production.

• Reliability: SMD resistors are typically more reliable than their through-hole counterparts, especially in automated assembly processes, as they are less prone to damage.

• Stable Performance: These resistors provide consistent resistance values over time and under different operating conditions, ensuring reliable circuit behavior.
