Description

A 22K Ohm 2W 5% Through Hole Resistor is a type of fixed resistor widely used in electronic circuits for current limitation, voltage division, and signal conditioning. It has a resistance value of 22,000 ohms (22KΩ), which makes it suitable for a wide range of applications in both low and medium-power circuits.

Key Features:

• Resistance Value: 22KΩ, indicating that the resistor offers 22,000 ohms of resistance to the flow of electrical current. The resistance value determines how much current will flow for a given applied voltage according to Ohm’s law (I = V/R).

• Power Rating: 2W (2 watts). This refers to the maximum amount of power the resistor can safely dissipate without being damaged. Resistors with higher power ratings are used in circuits with larger currents or voltages. The 2W rating allows this resistor to be used in medium-power applications where heat dissipation is a concern.

• Tolerance: 5%, which means the actual resistance value can vary by ±5% from the nominal value of 22KΩ. This tolerance range is typical for general-purpose resistors and is often acceptable for most consumer electronics applications where precise resistance isn't critical.

• Through Hole Mounting: This resistor features a through-hole design, which means it has metal leads on both ends that are designed to be inserted into holes in a printed circuit board (PCB) and soldered in place. This type of mounting is common in traditional and DIY electronic projects, providing a stable mechanical connection to the board.

• Construction: Typically constructed with a ceramic core and coated with a resistive material. The ceramic body helps in heat dissipation, allowing the resistor to handle higher power without overheating. The resistor is often encased in a protective epoxy or paint that ensures it remains durable and resistant to environmental factors.

• Applications: These resistors are used in a wide range of applications such as:

  • Voltage dividers
  • Signal conditioning circuits
  • Filtering applications
  • Current-limiting circuits
  • Audio electronics
  • Low-power power supply circuits

Physical Characteristics:

• Size: These resistors are typically compact, with a size that allows them to fit into standard PCB spaces for through-hole components.
• Color Code: 22KΩ resistors typically follow the standard resistor color code, which for 22KΩ is Red, Red, Orange, Gold (Red = 2, Red = 2, Orange = multiplier of 1,000, Gold = ±5% tolerance).

This resistor is a reliable, versatile component suitable for general-purpose use in both commercial and hobbyist electronics. Whether you're building simple circuits or more complex devices, the 22K Ohm 2W 5% Through Hole Resistor ensures consistent performance while helping control current and voltage in your designs.
