Additional Information

When handling resistors, it is essential to ensure that the leads are not bent or damaged, as this can affect the component's performance and reliability.

Resistors should be stored in a cool, dry place, away from direct sunlight and moisture.

It is recommended to follow proper soldering techniques when assembling circuits with resistors to ensure reliable connections and minimize the risk of damage.

Packaging Information

The 4.7k Ohm Resistor is supplied in a pack of 10 resistors, carefully packaged to prevent damage during transportation and storage. The packaging may vary depending on the manufacturer and supplier, but it typically includes a plastic or paper tape reel or a small plastic bag with a label indicating the component's specifications.

Pin Configuration

Component Documentation: 4.7k Ohm Resistor (Pack of 10)
Introduction:
The 4.7k Ohm Resistor is a passive electronic component that offers a fixed resistance value of 4.7 kilohms to the electrical circuit. It is commonly used in various IoT applications, including voltage dividers, signal attenuation, and impedance matching. This documentation provides a detailed overview of the component's pins and how to connect them.
Pinout:
A standard 4.7k Ohm Resistor has two pins, labeled as follows:
Pin 1:
Function: One end of the resistor
Description: This pin is one terminal of the resistor, which provides a connection point for the circuit.
Connection: Connect to a voltage source, signal source, or another component in the circuit.
Pin 2:
Function: Another end of the resistor
Description: This pin is the other terminal of the resistor, which provides a connection point for the circuit.
Connection: Connect to a load, ground, or another component in the circuit.
Connecting the Pins:
To connect the pins of the 4.7k Ohm Resistor, follow these steps:
1. Identify the pins: Verify the pin labels (Pin 1 and Pin 2) on the resistor package.
2. Determine the connection: Based on your circuit design, decide which component or point in the circuit to connect Pin 1 and Pin 2 to.
3. Connect Pin 1: Attach Pin 1 to the desired voltage source, signal source, or component in the circuit.
4. Connect Pin 2: Attach Pin 2 to the desired load, ground, or component in the circuit.
Important Notes:
The resistor is a non-polarized component, meaning it can be connected in either direction in the circuit.
Ensure the resistor is connected to the correct points in the circuit to avoid damage or incorrect operation.
The 4.7k Ohm Resistor has a limited power rating; do not exceed the maximum power dissipation to avoid overheating or damage.
Example Circuit:
Here is a simple example circuit to illustrate the connection of the 4.7k Ohm Resistor:
| Component | Pin 1 Connection | Pin 2 Connection |
| --- | --- | --- |
| 4.7k Ohm Resistor | 5V Power Supply | LED Anode (via another resistor) |
| LED | Resistor Pin 2 | Ground |
In this example, the 4.7k Ohm Resistor is used to limit the current flowing through the LED, while another resistor is used to drop the voltage to the LED's required level. The resistor is connected between the 5V power supply and the LED anode, with the other end of the resistor connected to the LED anode via another resistor.
Remember to always follow proper safety precautions and consult relevant datasheets or documentation for specific circuit design and implementation.
