Description

A 150 Ohm 1/4W 5% Through Hole Resistor is a specific type of resistor with the following characteristics:

Resistance Value (150 Ohms):

This resistor has a resistance of 150 ohms, meaning it provides a moderate level of opposition to the flow of electrical current. A 150-ohm resistor is commonly used in a wide variety of applications, such as current limiting, voltage division, and signal processing. It is often employed in low- to medium-power circuits, including LED current-limiting, voltage divider networks, and filtering applications.

Power Rating (1/4W):

The 1/4 watt (0.25W) power rating indicates that the resistor can safely dissipate up to 0.25 watts of heat. This power rating is ideal for typical low-power circuits where the current passing through the resistor is not large enough to produce significant heat. It ensures that the resistor will operate safely without overheating under normal conditions in most general-purpose circuits.

Tolerance (5%):

The 5% tolerance means that the actual resistance value of the resistor could vary by ±5% from the nominal value of 150 ohms. Therefore, the actual resistance could range from 142.5 ohms to 157.5 ohms. This tolerance is typical for general-purpose resistors and is suitable for most applications where precision is not extremely 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. Through-hole mounting provides a strong, reliable electrical and mechanical connection, making it a popular choice for both prototyping and permanent circuit designs. It’s especially useful when the components may need to be replaced or modified in the future.

Applications:

• Current Limiting: A 150-ohm resistor is frequently used in series with components like LEDs to limit the current, ensuring that the component doesn’t receive too much current that could cause damage.
• Voltage Division: It can be used in voltage divider circuits, where it helps create specific voltage levels that are needed by other components in the circuit.
• Impedance Matching: In audio, RF (radio frequency), or communication circuits, a 150-ohm resistor may be used for impedance matching to ensure efficient signal transfer and minimize signal reflections between components.
• Power Regulation: The resistor can also be used in power regulation applications to help control the current or voltage levels that other parts of the circuit need for stable operation.

Summary:

The 150 Ohm 1/4W 5% Through Hole Resistor is a general-purpose resistor commonly used for current limiting, voltage division, impedance matching, and power regulation in low- to medium-power circuits. With a 1/4W power rating, it can safely dissipate heat under typical operating conditions. The 5% tolerance provides reasonable accuracy for most general-purpose applications. The through-hole mounting ensures a stable and durable connection, making it ideal for both prototyping and finalized circuit designs where component reliability and ease of modification or replacement are important.
