Description

A 22 Ohm 1/4W 5% Through Hole Resistor is a specific type of resistor with the following characteristics:

Resistance Value (22 Ohms):

This resistor has a resistance of 22 ohms, meaning it provides a moderate resistance to the flow of electrical current. A 22-ohm resistor is commonly used in circuits where you need to limit current, create voltage dividers, or control power dissipation. It's typically found in applications like LED current limiting, signal processing, power regulation, and in some audio or impedance matching circuits.

Power Rating (1/4W):

The 1/4 watt (0.25W) power rating means that the resistor is designed to safely dissipate up to 0.25 watts of heat without damage. For a 22-ohm resistor, the power dissipation will generally be low to moderate, making it well-suited for low-power circuits where the current passing through is not high enough to cause excessive heat buildup. This ensures safe operation in typical low-power applications.

Tolerance (5%):

The 5% tolerance means that the actual resistance of the resistor could vary by ±5% from the nominal value of 22 ohms. The actual resistance could therefore range between 20.9 ohms and 23.1 ohms. This level of tolerance is common in general-purpose resistors and is generally acceptable in most applications that do not require high precision.

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 into place. Through-hole mounting provides a strong mechanical connection, making the resistor more durable and easier to handle. It’s ideal for both prototyping and final designs where durability, reliability, and ease of modification are important.

Applications:

• Current Limiting: A 22-ohm resistor is often used in circuits where current needs to be limited, such as with LEDs or other low-power components that could be damaged by excessive current.
• Voltage Division: It can be part of a voltage divider network, where it helps create specific voltage levels required for other components in the circuit.
• Impedance Matching: In audio, RF (radio frequency), or other signal processing circuits, it may be used to match the impedance between components, optimizing signal flow and reducing signal reflections.
• Power Regulation: The resistor can be used in power supply circuits to regulate current flow, ensuring that components receive the correct voltage and current for safe operation.

Summary:

The 22 Ohm 1/4W 5% Through Hole Resistor is a general-purpose resistor ideal for current limiting, voltage division, impedance matching, and power regulation in low-power circuits. The 1/4W power rating ensures it can dissipate heat safely under typical circuit conditions, while the 5% tolerance ensures it performs accurately enough for most general-purpose applications. The through-hole mounting style provides durability and strong mechanical connections, making it suitable for both prototyping and final designs where easy replacement or modification is necessary.
