Description

A 470 Ohm 1/4W 5% Through Hole Resistor is a specific type of resistor with the following characteristics:

Resistance Value (470 Ohms):

This resistor has a resistance of 470 ohms, which means it offers moderate opposition to the flow of electrical current. It is commonly used in various electronic circuits to control the amount of current that flows, to create voltage dividers, or to provide impedance matching. A 470-ohm resistor is often found in low- to medium-power applications, such as limiting current to LEDs, setting bias points for transistors, or as part of analog signal processing.

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 without overheating or being damaged. This power rating is suitable for low-power applications where the current flowing through the resistor does not generate excessive heat. The 1/4W rating ensures the resistor can handle typical currents in low- to medium-power circuits without risking failure due to heat buildup.

Tolerance (5%):

The 5% tolerance means the actual resistance can vary by ±5% from the nominal value of 470 ohms. Therefore, the actual resistance could range from 446.5 ohms to 493.5 ohms. This tolerance is typical for general-purpose resistors and is acceptable for most applications where precise resistance values are not critical.

Through-Hole Mounting:

This resistor is designed for through-hole mounting, which means it has leads that pass through holes in a printed circuit board (PCB) and are soldered on the opposite side. Through-hole components are widely used because they provide strong, reliable mechanical and electrical connections. They are especially useful in both prototyping and production designs where ease of modification or replacement is important.

Applications:

• Current Limiting: A 470-ohm resistor is frequently used to limit current in circuits, such as in series with LEDs to ensure they do not receive too much current, which could damage them.
• Voltage Division: It is often used in voltage divider circuits to reduce the voltage to a desired level, providing different voltage rails to various parts of a circuit.
• Impedance Matching: In audio, RF (radio frequency), or communication circuits, a 470-ohm resistor can be used to match the impedance between components to ensure efficient signal transfer and reduce reflections.
• Power Regulation: This resistor can be used in power regulation circuits, where it helps control the amount of voltage or current flowing through other parts of the circuit, ensuring stable operation.

Summary:

The 470 Ohm 1/4W 5% Through Hole Resistor is a versatile, general-purpose resistor used in a variety of electronic applications, such as current limiting, voltage division, impedance matching, and power regulation. With a 1/4W power rating, it is designed to handle low-power circuits, while the 5% tolerance ensures acceptable accuracy for most general-purpose designs. The through-hole mounting ensures secure and reliable connections, making it a reliable choice for both prototyping and final circuit designs where durability, ease of repair, or modification is important.
