Description

A 75 Ohm 1/4W 5% Through Hole Resistor is a specific type of resistor with the following characteristics:

Resistance Value (75 Ohms):

This resistor has a resistance of 75 ohms, which provides a moderate level of resistance to the flow of electrical current. A 75-ohm resistor is commonly used in applications where controlling current flow, creating voltage dividers, or regulating power dissipation is needed. It is often used in low- to medium-power circuits, such as current-limiting applications (e.g., LEDs), voltage divider networks, and signal processing circuits.

Power Rating (1/4W):

The 1/4 watt (0.25W) power rating means this resistor is designed to safely dissipate up to 0.25 watts of heat. This is more than enough for typical low-power applications, where the resistor will not dissipate excessive heat. The 1/4W rating ensures that the resistor can handle moderate current levels without the risk of overheating, making it suitable for a wide range of standard applications.

Tolerance (5%):

The 5% tolerance means that the actual resistance can vary by ±5% from the nominal value of 75 ohms. The actual resistance could therefore range from 71.25 ohms to 78.75 ohms. This tolerance is typical for general-purpose resistors and is acceptable in most circuits where high precision is 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 solid mechanical and electrical connection, making it ideal for prototyping, assembling, or finalizing durable circuit designs. It's especially useful when the components may need to be replaced or modified over time.

Applications:

• Current Limiting: A 75-ohm resistor is frequently used in circuits to limit the current, such as in series with LEDs or other components that need to have their current flow regulated to prevent damage.
• Voltage Division: It can be used in voltage divider networks, where it helps divide the input voltage into smaller, specific voltages that can be fed to other parts of the circuit.
• Impedance Matching: In audio or RF (radio frequency) applications, a 75-ohm resistor can be used for impedance matching, ensuring that the components in the circuit work together efficiently, reducing signal reflections and maximizing signal transfer.
• Power Regulation: The resistor can also be part of power regulation circuits to control voltage and current, ensuring the safe operation of sensitive components.

Summary:

The 75 Ohm 1/4W 5% Through Hole Resistor is a reliable, general-purpose resistor that can be used in various applications such as current limiting, voltage division, impedance matching, and power regulation in low- to medium-power circuits. The 1/4W power rating ensures it can safely dissipate heat under typical operating conditions, while the 5% tolerance offers sufficient accuracy for most standard applications. The through-hole mounting design ensures a durable and stable connection, making it ideal for both prototyping and finalized circuit designs, where component durability and ease of replacement or modification are required.
