Description

The 100K Ohm 1/2W 5% Through Hole Resistor is an essential component in electronic circuits, commonly used for current limiting, voltage division, and signal processing. With a resistance value of 100K ohms (100,000 ohms), a power rating of 1/2 watt (0.5W), and a 5% tolerance, this resistor is ideal for moderate power applications. The through-hole mounting design ensures a secure connection on printed circuit boards (PCBs), making it suitable for both prototyping and production use.

Key Specifications:

• Resistance: 100K ohms (100,000 ohms)

  • The 100K ohm resistor is typically used in circuits where higher resistance is needed to limit current or scale down voltage. It is widely used in voltage divider circuits, signal conditioning, and other applications that require controlling voltage or current flow.

• Power Rating: 1/2 watt (0.5W)

  • This resistor can safely dissipate 0.5 watts of electrical power without overheating, making it suitable for low-to-medium power circuits.

• Tolerance: ±5%

  • The 5% tolerance means the actual resistance value can vary by 5% from the nominal value. For the 100K ohm resistor, the actual resistance could range from 95,000 ohms to 105,000 ohms.

• Mounting Type: Through-hole

  • The through-hole mounting design features metal leads that are inserted through holes in the PCB, ensuring a stable and reliable electrical connection through soldering. This mounting type is commonly used in both prototype and mass production circuits.

Applications:

• Current Limiting:
  The 100K ohm resistor is frequently used in current-limiting applications to protect sensitive components such as LEDs, transistors, and microcontrollers by reducing the amount of current flowing through the circuit.

• Voltage Regulation:
  This resistor is used in voltage regulation circuits to help maintain a stable voltage level, preventing voltage fluctuations from damaging electronic components.

• Voltage Divider Circuits:
  The 100K ohm resistor is often used in voltage divider circuits, where it is paired with other resistors to reduce higher voltage levels to safe and usable levels for sensors, analog-to-digital converters (ADC), or other measurement systems.

• Signal Processing and Filtering:
  The 100K ohm resistor plays a key role in signal processing and filtering applications. It helps stabilize and filter signals in systems such as audio amplifiers, RF circuits, and noise reduction circuits.

Physical Characteristics:

• Size:
  The 1/2 watt resistor typically measures around 1/4 inch (6.35 mm) in length and 1/8 inch (3.18 mm) in diameter. However, dimensions may slightly vary depending on the manufacturer.

• Construction:
  The resistor has a cylindrical body with metal leads extending from both ends. These leads are inserted into holes in the PCB and soldered to form a stable, reliable electrical connection.

Summary:
The 100K Ohm 1/2W 5% Through Hole Resistor is a dependable and versatile electronic component. With a 100K ohm resistance, 1/2 watt power rating, and 5% tolerance, this resistor is perfect for moderate power applications.
