Description

A 680 Ohm 1/4W 5% Through Hole Resistor is a specific type of resistor with the following characteristics:

Resistance Value (680 Ohms):

This resistor has a resistance of 680 ohms, which provides a moderate opposition to the flow of electrical current. It is commonly used in circuits that require current limiting, voltage division, or impedance matching. A 680-ohm resistor can be found in a wide variety of low- to medium-power applications, such as LED circuits, signal processing, and analog or digital circuitry that requires stable current flow.

Power Rating (1/4W):

The 1/4 watt (0.25W) power rating means that the resistor can safely dissipate up to 0.25 watts of heat without risk of damage. This power rating is well-suited for low-power circuits where the resistor is not exposed to high currents or excessive heat. The 1/4W rating ensures the resistor performs reliably and safely under typical operating conditions in most general-purpose electronic designs.

Tolerance (5%):

The 5% tolerance means that the actual resistance value could vary by ±5% from the nominal value of 680 ohms. As a result, the actual resistance could range from 646 ohms to 714 ohms. This tolerance is standard for general-purpose resistors and is acceptable for most applications where precise resistance is not critical but where consistency is still important.

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 to the opposite side. Through-hole components are typically used for their durability and strong mechanical connections, making them ideal for both prototyping and permanent circuit assemblies. This type of mounting is particularly useful when the resistor may need to be replaced or modified later.

Applications:

• Current Limiting: A 680-ohm resistor is often used in series with LEDs or other current-sensitive components to limit the current passing through them, preventing damage from excessive current.
• Voltage Division: It is frequently used in voltage divider circuits to reduce a higher voltage to a lower, more manageable level, which can be useful for feeding lower voltage signals to other parts of the circuit.
• Impedance Matching: In audio, RF (radio frequency), and communication circuits, a 680-ohm resistor can be used to match the impedance between components, ensuring efficient signal transfer and minimizing reflection.
• Power Regulation: It can also be employed in power regulation circuits to control the current or voltage delivered to other parts of a circuit, helping to maintain stable operation.

Summary:

The 680 Ohm 1/4W 5% Through Hole Resistor is a versatile, general-purpose resistor suitable for a wide range of electronic applications such as current limiting, voltage division, impedance matching, and power regulation. With its 1/4W power rating, it is designed to handle low-power circuits, while the 5% tolerance ensures that it provides sufficient accuracy for most typical designs. The through-hole mounting makes it durable and reliable, making this resistor a solid choice for both prototyping and production environments where ease of repair, modification, and replacement is important.
