Description

A 68 Ohm 1/4W 5% Through Hole Resistor is a specific type of resistor with the following characteristics:

Resistance Value (68 Ohms):

This resistor has a resistance of 68 ohms, meaning it provides a moderate opposition to the flow of electrical current. A 68-ohm resistor is commonly used in circuits where you need to limit current, create voltage dividers, or control power dissipation. It can be found in applications like current limiting for LEDs, impedance matching, and voltage divider networks in a variety of low- to medium-power electronic 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. In typical low-power applications, a 68-ohm resistor can safely handle the current passing through it without overheating. The 1/4W power rating is suitable for general-purpose uses where current levels are not high enough to require a higher power rating.

Tolerance (5%):

The 5% tolerance indicates that the actual resistance of the resistor could vary by ±5% from the nominal value of 68 ohms. The actual resistance could range from 64.6 ohms to 71.4 ohms. The 5% tolerance is typical for general-purpose resistors, making it acceptable for most applications where precise resistance values are not critical.

Through-Hole Mounting:

This resistor is designed for through-hole mounting, which means it has leads that pass through holes in a printed circuit board (PCB) and are soldered on the opposite side. Through-hole resistors provide a strong and durable mechanical and electrical connection, making them ideal for both prototyping and permanent designs, especially in applications where reliability, ease of replacement, or modifications are required.

Applications:

• Current Limiting: A 68-ohm resistor is commonly used in circuits where current needs to be limited, such as in series with LEDs to prevent excessive current that could damage the component.
• Voltage Division: It can be used in voltage divider circuits, where it helps create specific voltage levels required by other components in the circuit.
• Impedance Matching: In audio and RF (radio frequency) applications, a 68-ohm resistor can be used for impedance matching, ensuring optimal signal transfer and minimizing signal reflections between components.
• Power Regulation: The resistor can also be used in power regulation circuits, where controlling the voltage or current is necessary to maintain safe and efficient operation of other components in the system.

Summary:

The 68 Ohm 1/4W 5% Through Hole Resistor is a general-purpose resistor used in applications like current limiting, voltage division, impedance matching, and power regulation. The 1/4W power rating ensures it can safely dissipate heat under typical low-power conditions, while the 5% tolerance provides sufficient accuracy for most general-purpose uses. The through-hole mounting ensures a durable and reliable mechanical connection, making it ideal for prototyping, testing, and final circuit designs where strong connections are necessary and component replacement or modification is needed.
