Description

A 220 Ohm 1/4W 5% Through Hole Resistor is a specific type of resistor with the following characteristics:

Resistance Value (220 Ohms):

This resistor has a resistance of 220 ohms, meaning it offers moderate opposition to the flow of electrical current. A 220-ohm resistor is typically used in various applications that require current limiting, voltage division, and signal conditioning. It is suitable for low- to medium-power circuits, such as limiting current in LED circuits, creating voltage dividers, and controlling current in various analog or digital circuits.

Power Rating (1/4W):

The 1/4 watt (0.25W) power rating indicates that this resistor can safely dissipate up to 0.25 watts of heat without damage. The 1/4W power rating is ideal for most low-power applications where the current flowing through the resistor is not high enough to generate significant heat. It ensures the resistor operates within safe thermal limits, making it suitable for general-purpose circuits.

Tolerance (5%):

The 5% tolerance means that the actual resistance value could vary by ±5% from the nominal value of 220 ohms. Therefore, the actual resistance could range from 209 ohms to 231 ohms. This tolerance is typical for general-purpose resistors and is generally acceptable for most circuit applications where precise resistance values are not critical.

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. This mounting style provides a secure, durable connection and is widely used for both prototyping and finalized circuit assemblies. It is especially useful when the circuit may need to be modified, repaired, or components replaced over time.

Applications:

• Current Limiting: A 220-ohm resistor is commonly used to limit the current flowing through components, such as LEDs, to prevent damage from excessive current.
• Voltage Division: It can be used in voltage divider circuits to reduce an input voltage into smaller, desired levels for other components or stages of the circuit.
• Impedance Matching: In audio, RF (radio frequency), or communication circuits, a 220-ohm resistor can be used for impedance matching to ensure efficient signal transfer and minimize reflections between components.
• Power Regulation: The resistor can also be employed in power regulation circuits to control voltage and current levels, ensuring that other components receive the appropriate power supply.

Summary:

The 220 Ohm 1/4W 5% Through Hole Resistor is a general-purpose resistor used in a variety of applications, including current limiting, voltage division, impedance matching, and power regulation. The 1/4W power rating ensures it can safely handle low-power circuits, while the 5% tolerance offers reasonable accuracy for most general-purpose applications. The through-hole mounting design ensures a reliable and durable connection, making it ideal for both prototyping and finalized designs where component durability, ease of modification, and replacement are important.
