Description

A 240 Ohm 1/4W 5% Through Hole Resistor is a specific type of resistor with the following characteristics:

Resistance Value (240 Ohms):

This resistor has a resistance of 240 ohms, providing a moderate level of opposition to the flow of electrical current. It is commonly used in circuits where current needs to be controlled, such as limiting current in LED circuits, voltage dividers, or signal processing applications. With its resistance value, it helps reduce the current flow and maintain safe operating conditions for various components in a circuit.

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 being damaged. This rating is ideal for low-power applications, where the current passing through the resistor is not high enough to generate excessive heat. The 1/4W power rating ensures that the resistor remains within safe thermal limits during typical usage.

Tolerance (5%):

The 5% tolerance means that the actual resistance could vary by ±5% from the nominal value of 240 ohms. Therefore, the actual resistance could range from 228 ohms to 252 ohms. This tolerance is typical for general-purpose resistors and is suitable for most applications where high precision is not critical, allowing for a balance between cost and performance.

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 components provide strong mechanical and electrical connections, making them ideal for both prototyping and finalized circuit assemblies. This type of mounting ensures durability and is often used when modifications or replacements may be needed in the future.

Applications:

• Current Limiting: A 240-ohm resistor is commonly used in series with components like LEDs to limit the current and prevent overcurrent that could damage the component.
• Voltage Division: It can be used in voltage divider circuits, where it helps split an input voltage into smaller, more manageable levels for feeding other parts of the circuit.
• Impedance Matching: In audio, RF (radio frequency), or communication circuits, a 240-ohm resistor is useful for impedance matching to ensure efficient signal transfer and minimize signal reflections.
• Power Regulation: It can be used in power regulation circuits to control current or voltage levels, ensuring that other components operate within their specified limits.

Summary:

The 240 Ohm 1/4W 5% Through Hole Resistor is a versatile, general-purpose resistor used for current limiting, voltage division, impedance matching, and power regulation in low- to medium-power circuits. The 1/4W power rating ensures it can safely handle typical low-power currents without generating excessive heat, while the 5% tolerance offers reasonable accuracy for most general-purpose applications. The through-hole mounting ensures a strong, reliable connection, making it ideal for both prototyping and finalized designs where component durability, ease of replacement, or modification is important.
