Description

A 47 Ohm 1/4W 5% Through Hole Resistor is a specific type of resistor with the following characteristics:

Resistance Value (47 Ohms):

This resistor has a resistance of 47 ohms, which provides a moderate opposition to the flow of electrical current. It is commonly used in circuits requiring current limiting, voltage division, or power regulation. A 47-ohm resistor can be found in applications such as LED current limiting, signal processing, and voltage divider networks in low- to medium-power circuits.

Power Rating (1/4W):

The 1/4 watt (0.25W) power rating means that this resistor is designed to safely dissipate up to 0.25 watts of heat. For most low-power applications, this power rating is more than adequate to ensure that the resistor operates efficiently and does not overheat. In typical use cases, the current flowing through the 47-ohm resistor will remain within the safe thermal limits, ensuring reliable performance.

Tolerance (5%):

The 5% tolerance means that the actual resistance value of the resistor can vary by ±5% from the nominal value of 47 ohms. This gives the resistor a range of 44.65 ohms to 49.35 ohms. This level of tolerance is typical for general-purpose resistors and is suitable for most applications where high precision is not 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 ensures a strong, stable mechanical and electrical connection, which makes the resistor ideal for both prototyping and permanent circuit designs, especially when durability, easy replacement, or modifications are important.

Applications:

• Current Limiting: A 47-ohm resistor is commonly used in circuits to limit current, such as in series with LEDs to protect them from excessive current that could damage the component.
• Voltage Division: It can be part of a voltage divider network, helping create specific voltage levels required by other components in the circuit.
• Impedance Matching: In audio and RF (radio frequency) applications, the 47-ohm resistor can be used to match impedance between components, ensuring efficient signal transfer and reducing signal reflections.
• Power Regulation: The resistor can also be used in power supply circuits where controlling the voltage or current is necessary to prevent overloading or to stabilize the circuit.

Summary:

The 47 Ohm 1/4W 5% Through Hole Resistor is a reliable, general-purpose resistor used in various applications such as current limiting, voltage division, and power regulation. The 1/4W power rating ensures safe operation in low-power applications, while the 5% tolerance provides adequate accuracy for most typical circuits. The through-hole mounting style guarantees a durable connection, making it ideal for prototyping and final circuit designs, especially in situations requiring strong mechanical connections or ease of modification.
