Description

A 82 Ohm 1/4W 5% Through Hole Resistor is a specific type of resistor with the following characteristics:

Resistance Value (82 Ohms):

This resistor has a resistance of 82 ohms, which offers moderate opposition to the flow of electrical current. A 82-ohm resistor is commonly used in circuits for current limiting, voltage division, or power dissipation control. It's often used in applications like LED current limiting, signal conditioning, and voltage divider circuits, especially in low- to medium-power electronics.

Power Rating (1/4W):

The 1/4 watt (0.25W) power rating means that this resistor can safely dissipate up to 0.25 watts of heat. The 1/4W rating is suitable for typical low-power circuits, where the resistor won't dissipate significant heat. This ensures that the resistor operates safely under standard conditions, without overheating when handling moderate current levels.

Tolerance (5%):

The 5% tolerance means that the actual resistance value of the resistor can vary by ±5% from the nominal value of 82 ohms. The actual resistance could therefore range from 77.9 ohms to 86.1 ohms. The 5% tolerance is common for general-purpose resistors and is acceptable in most circuits that don't require extremely tight resistance control.

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 mounting ensures a solid, durable connection and is ideal for applications where the resistor may need to be replaced or the circuit modified. It's commonly used in both prototyping and final circuit designs.

Applications:

• Current Limiting: A 82-ohm resistor is often used to limit the current flowing through a circuit, particularly when used in series with LEDs to prevent excessive current that could damage the LED or other sensitive components.
• Voltage Division: It can be part of a voltage divider network, helping to create specific voltage levels required by other components in the circuit.
• Impedance Matching: In audio, RF (radio frequency), or communication circuits, a 82-ohm resistor is useful for impedance matching, optimizing signal transfer and reducing reflections between components.
• Power Regulation: The resistor can be used in power regulation circuits to control the voltage or current being supplied to other components in the system.

Summary:

The 82 Ohm 1/4W 5% Through Hole Resistor is a general-purpose resistor that is widely used in circuits for current limiting, voltage division, impedance matching, and power regulation. The 1/4W power rating ensures it can handle moderate currents without overheating, while the 5% tolerance provides sufficient accuracy for most applications. The through-hole mounting design offers a reliable and durable connection, making it ideal for both prototyping and finalized circuit designs where component stability, reliability, and ease of modification are needed.
