Description

A 750 Ohm 1/4W 5% Through Hole Resistor is a specific type of resistor with the following characteristics:

Resistance Value (750 Ohms):

This resistor has a resistance of 750 ohms, providing moderate opposition to the flow of electrical current. It is typically used in applications where precise control of current or voltage is needed, such as current-limiting for LEDs, voltage dividers, or biasing circuits for transistors and operational amplifiers. A 750-ohm resistor is often found in medium-power circuits where you need to regulate current flow or set specific voltage levels.

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. This power rating is appropriate for low- to medium-power applications where the resistor does not generate excessive heat. The 1/4W rating ensures the resistor operates within safe limits for typical applications without the risk of overheating or failure.

Tolerance (5%):

The 5% tolerance means that the actual resistance can vary by ±5% from the nominal value of 750 ohms. As a result, the actual resistance could range from 712.5 ohms to 787.5 ohms. This tolerance is typical for general-purpose resistors and is acceptable for most designs where slight variations in resistance do not significantly affect the circuit's performance.

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 components are favored for their strong and reliable mechanical and electrical connections, making them ideal for both prototyping and permanent circuit assemblies. This type of mounting is particularly useful when the resistor needs to be easily replaced or modified.

Applications:

• Current Limiting: A 750-ohm resistor is often used to limit current in circuits, such as in series with LEDs to prevent excessive current from damaging sensitive components.
• Voltage Division: It is commonly used in voltage divider circuits, where it helps reduce the input voltage to lower, more manageable levels suitable for other parts of the circuit.
• Impedance Matching: In audio, RF (radio frequency), or communication circuits, a 750-ohm resistor can be used for impedance matching, ensuring efficient signal transfer and minimizing reflections between components.
• Power Regulation: It can be used in power regulation circuits to control the flow of voltage or current, helping to maintain proper operation of other components in the system.

Summary:

The 750 Ohm 1/4W 5% Through Hole Resistor is a general-purpose resistor used in a variety of applications, such as current limiting, voltage division, impedance matching, and power regulation. With its 1/4W power rating, it is well-suited for low- to medium-power circuits, while the 5% tolerance provides an acceptable range of accuracy for most designs. The through-hole mounting ensures durable and reliable connections, making it ideal for both prototyping and final circuit assemblies where ease of modification, repair, and replacement is necessary.
