Description

A 2.2 Ohm 1/4W 5% Through Hole Resistor is a specific type of resistor with the following characteristics:

Resistance Value (2.2 Ohms):

This resistor has a resistance of 2.2 ohms, meaning it provides a moderate amount of opposition to the flow of electric current in a circuit. The 2.2 ohm resistance is suitable for limiting current, voltage division, or controlling power dissipation in a variety of applications, particularly in low-power circuits where a precise resistance is required.

Power Rating (1/4W):

The 1/4 watt (0.25W) power rating means the resistor is designed to safely dissipate up to 0.25 watts of heat without overheating or being damaged. While the resistor does present some resistance to current flow, the relatively low power rating indicates that it is intended for use in low-power applications. It ensures that the resistor can handle heat generated by current flow without failure.

Tolerance (5%):

The 5% tolerance indicates that the actual resistance of the resistor could vary by as much as ±5% from the nominal 2.2 ohms. This tolerance range is typical for general-purpose resistors and means that the resistor will usually fall within the range of 2.09 ohms to 2.31 ohms. While there is some variation, the resistor is still accurate enough for most standard applications.

Through-Hole Mounting:

This resistor is designed for through-hole mounting, meaning it has leads that pass through holes in a printed circuit board (PCB) and are soldered on the opposite side. Through-hole resistors are widely used in applications where mechanical strength, durability, and ease of repair are important. This mounting style ensures a stable connection and is especially useful in prototyping or situations where the component might be replaced or modified in the future.

Applications:

• Current Limiting: The 2.2 ohm resistor is commonly used to limit current in low-power circuits, such as LED drivers or other small electronic devices.
• Voltage Division: It can be used in voltage divider circuits, where precise resistance is needed to create specific voltage levels for other components.
• Filtering and Decoupling: This resistor might also be used in filter circuits to control noise or provide load balancing.
• Power Distribution: In some cases, it could be used to distribute or share power evenly between components or sections of a circuit.

Summary:

The 2.2 Ohm 1/4W 5% Through Hole Resistor is typically used in circuits where moderate current limiting, voltage division, or filtering is required. The 1/4W power rating and 5% tolerance ensure that the resistor can safely dissipate heat in low-power applications while maintaining a reasonable level of accuracy. Through-hole mounting makes it ideal for durable and easily replaceable connections on a printed circuit board.
