Description

A 56 Ohm 1/4W 5% Through Hole Resistor is a specific type of resistor with the following characteristics:

Resistance Value (56 Ohms):

This resistor has a resistance of 56 ohms, meaning it provides a moderate level of opposition to the flow of electrical current. It’s commonly used in circuits where you need to limit current, divide voltage, or regulate power. A 56-ohm resistor is typically found in applications like current limiting for LEDs, voltage dividers, and other low- to medium-power 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 without being damaged. For a 56-ohm resistor, this is well-suited for low-power applications where the current passing through the resistor is not high enough to generate significant heat. The 1/4W rating ensures that the resistor operates within safe thermal limits in typical use.

Tolerance (5%):

The 5% tolerance means that the actual resistance of the resistor can vary by ±5% from the nominal value of 56 ohms. The actual resistance could therefore range from 53.2 ohms to 58.8 ohms. This tolerance level is typical for general-purpose resistors and is suitable for most circuits where precise resistance is not a strict requirement.

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 resistors provide a solid mechanical and electrical connection, making them ideal for applications where durability, reliability, and ease of replacement or modification are important.

Applications:

• Current Limiting: A 56-ohm resistor is often used to limit current in circuits, such as in series with LEDs to prevent overcurrent that could damage the component.
• Voltage Division: It can be used in voltage divider circuits, where it helps divide the input voltage into specific, lower voltage levels required for other components.
• Impedance Matching: In audio and RF (radio frequency) circuits, a 56-ohm resistor is commonly used for impedance matching, ensuring efficient signal transfer and reducing signal reflections between components.
• Power Regulation: The resistor may also be used in power regulation circuits to control the flow of current and voltage, ensuring that other components receive the correct power levels.

Summary:

The 56 Ohm 1/4W 5% Through Hole Resistor is a general-purpose resistor that is suitable for applications like 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 provides enough accuracy for most applications. The through-hole mounting design ensures reliable and durable connections, making it ideal for both prototyping and finalized circuit designs, especially where component replacement or modification may be required.
