47 Ohm 1/4W 5% Copper Wire Through-Hole Resistor:

The 47 Ohm 1/4W 5% Copper Wire Through-Hole Resistor is a versatile, general-purpose electronic component commonly used for controlling the flow of electrical current in a variety of circuits. Below is a breakdown of its specifications:

1. Resistance Value (47 Ohms):

The 47 ohm resistance value means this resistor offers 47 ohms of opposition to the current flow. While higher than a low-value resistor (like a 2 ohm), this value still permits a moderate amount of current to pass through compared to much higher resistances.

• This resistor is typically used when you need a moderate current-limiting feature, especially in applications like signal conditioning, biasing circuits, and power supplies.
• It’s commonly used in LED circuits, motor drivers, and voltage divider networks where a moderate resistance is required to achieve the desired performance.

2. Power Rating (1/4W or 0.25W):

The 1/4 watt (0.25W) power rating indicates that this resistor can safely dissipate up to 0.25 watts of power as heat without exceeding its thermal limits.

• This power rating is standard for most general-purpose resistors, making it suitable for low-to-moderate-power applications.
• It's essential to ensure that the resistor doesn’t exceed this power rating, as overheating can cause damage to the component and potentially the surrounding circuitry.

3. Tolerance (5%):

The 5% tolerance means that the actual resistance value of this resistor can deviate by up to ±5% from its nominal value of 47 ohms.

• In practice, this means the resistance could vary between 44.65 ohms and 49.35 ohms.
• The 5% tolerance is typical for general-purpose resistors and is acceptable for most common circuits. However, if your application requires high precision, resistors with tighter tolerances (such as 1% or 0.5%) may be preferred.

4. Copper Wire Construction:

This resistor uses copper wire as the material for its internal resistance element. Copper is known for its high conductivity and low resistance, making it an ideal choice for many resistor types.

• The copper wire construction helps improve the overall efficiency of current flow, ensuring minimal loss within the resistor.
• Copper wire resistors are often more cost-effective than their metal oxide or metal film counterparts, making them popular in budget-conscious designs while still offering solid performance.

5. Through-Hole Mounting:

This resistor is designed for through-hole mounting, meaning it has two metal leads that go through holes in the PCB and are soldered on the other side.

• Through-hole resistors are easy to handle, solder, and replace, which is why they are commonly used in traditional PCB designs.
• This type of mounting is also known for its durability, as the leads create a more robust connection to the PCB compared to surface-mount components.

6. Applications:

The 47 Ohm resistor is used in a wide range of applications, such as:

• Current Limiting: In LED circuits or other low-power devices where controlling the amount of current is essential for proper operation and to avoid damaging components.
• Voltage Division: It can be part of a voltage divider network when paired with other resistors to achieve a specific output voltage.
• Signal Filtering: It can be used in combination with capacitors or inductors to filter out unwanted noise in power supplies or audio circuits.
• Biasing: In amplifier or transistor circuits, it can be used to set the correct operating point for active devices.
• Pull-up/Pull-down Resistor: It can also function as a pull-up or pull-down resistor in digital logic circuits, ensuring that inputs to microcontrollers or logic gates maintain a defined state when not actively driven.

7. Summary:

The 47 Ohm 1/4W 5% Copper Wire Through-Hole Resistor is a general-purpose component suited for applications where moderate current regulation is needed. Its 47-ohm resistance, 1/4W power rating, and 5% tolerance make it ideal for low to moderate power circuits. The through-hole design provides robust and reliable connections in traditional PCB designs, and the copper wire construction ensures solid conductivity and efficient performance.

This resistor is widely used in circuits requiring current limiting, voltage division, filtering, and biasing, among many other tasks. It's a reliable and cost-effective choice for a variety of common electronics applications.
