Description

A 180 Ohm 1/4W 5% Through Hole Resistor is a specific type of resistor with the following characteristics:

Resistance Value (180 Ohms):

This resistor has a resistance of 180 ohms, providing a moderate level of resistance to the flow of electrical current. A 180-ohm resistor is commonly used in circuits for applications such as current limiting, voltage division, signal conditioning, and filtering. It is suitable for low- to medium-power applications, such as limiting current in LED circuits, creating voltage dividers, and controlling the flow of signals in analog circuits.

Power Rating (1/4W):

The 1/4 watt (0.25W) power rating means the resistor can safely dissipate up to 0.25 watts of heat without damage. The 1/4W rating is typically used in circuits where the current and power levels are low, and ensures that the resistor can handle normal operating conditions without overheating. It is ideal for general-purpose applications that don’t involve significant power dissipation.

Tolerance (5%):

The 5% tolerance means that the actual resistance can vary by ±5% from the nominal value of 180 ohms. The actual resistance could therefore range from 171 ohms to 189 ohms. This tolerance is typical for general-purpose resistors and is acceptable in most situations where high precision is not critical. The resistor will still function well within the desired range in most typical circuits.

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 provides a reliable mechanical and electrical connection, making it suitable for both prototyping and final circuit assemblies. It's especially useful when the circuit may need modifications, repairs, or component replacements over time.

Applications:

• Current Limiting: A 180-ohm resistor can be used in series with LEDs or other components to limit the current and prevent excessive current flow that could damage the components.
• Voltage Division: It is commonly used in voltage divider circuits to split an input voltage into smaller, specific levels that can be fed to other parts of the circuit.
• Impedance Matching: In audio, RF (radio frequency), or communication circuits, a 180-ohm resistor may be used for impedance matching, ensuring efficient signal transfer and minimizing signal reflections between components.
• Power Regulation: It can be used in power regulation applications to control the flow of voltage or current, helping maintain safe operating conditions for other components in the circuit.

Summary:

The 180 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 safe operation in typical low-power applications, while the 5% tolerance provides acceptable accuracy for most circuits. The through-hole mounting ensures reliable and durable connections, making it ideal for both prototyping and final circuit designs where component reliability and easy modification or replacement are important.
