Description

The 22K Ohm 1/2W 5% Through Hole Resistor is a commonly used electronic component designed for a variety of applications, including current limiting, voltage division, and signal processing. With a resistance value of 22K ohms (22,000 ohms), a power rating of 1/2 watt (0.5W), and a 5% tolerance, this resistor is well-suited for low-to-medium power circuits. Its through-hole mounting design allows for secure integration into printed circuit boards (PCBs), making it ideal for both prototyping and production environments.

Key Specifications:

• Resistance: 22K ohms (22,000 ohms)

  • The 22K ohm resistor is ideal for circuits requiring higher resistance to control current flow or reduce voltage levels. It is commonly used in voltage divider circuits, signal conditioning, and filtering applications.

• Power Rating: 1/2 watt (0.5W)

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

• Tolerance: ±5%

  • The 5% tolerance means the actual resistance value may vary by 5% from the nominal value. For the 22K ohm resistor, the resistance could range from 20,900 ohms to 23,100 ohms.

• Mounting Type: Through-hole

  • The through-hole mounting design allows the resistor’s leads to be inserted through holes in the PCB, where they are soldered to form a stable and reliable electrical connection. This type of mounting is used for both prototype designs and large-scale production.

Applications:

• Current Limiting:
  The 22K ohm resistor is commonly used in current-limiting applications to protect sensitive components, such as LEDs or transistors, from excessive current by controlling the flow of current through the circuit.

• Voltage Regulation:
  This resistor is also used in voltage regulation circuits to ensure a stable voltage supply for sensitive components by limiting voltage fluctuations.

• Voltage Divider Circuits:
  The 22K ohm resistor is ideal for voltage divider circuits, which are used to scale down higher voltages to a lower, safe value for sensors, analog-to-digital converters (ADC), or other measurement devices.

• Signal Processing and Filtering:
  The 22K ohm resistor is often used in signal processing and filtering applications, helping to stabilize or filter signals in systems such as audio amplifiers, RF circuits, and noise reduction systems.

Physical Characteristics:

• Size:
  The 1/2 watt resistor typically measures about 1/4 inch (6.35 mm) in length and 1/8 inch (3.18 mm) in diameter, although the exact size may vary depending on the manufacturer.

• Construction:
  The resistor features a cylindrical body with metal leads extending from both ends. These leads pass through holes in the PCB and are soldered to create a stable, reliable connection.

Summary:
The 22K Ohm 1/2W 5% Through Hole Resistor is a versatile and reliable component used in a variety of electronic circuits. With a resistance of 22K ohms, a 1/2 watt power rating, and a 5% tolerance, this resistor is ideal for moderate power applications. The through-hole mounting design ensures easy and secure integration into PCBs for both prototyping and mass production. Whether used for current limiting, voltage regulation, voltage division, or signal processing, this resistor offers consistent and dependable performance across a wide range of electronic applications.
