Component Name

470 Ohm Resistor (Pack of 10)

Description

The 470 Ohm Resistor is a pack of 10 axial-lead resistors, each with a resistance value of 470 ohms. Resistors are passive electronic components that oppose the flow of electric current in a circuit. They are commonly used to regulate voltage, current, and signal levels in a wide range of applications, including electronic circuits, microcontrollers, and IoT devices.

Functionality

The primary function of the 470 Ohm Resistor is to reduce the voltage or current in an electrical circuit. When connected in series with other components, the resistor absorbs or dissipates excess energy, preventing damage to sensitive components or circuits. The resistor's resistance value determines the amount of voltage or current it can handle, making it an essential component in many electronic designs.

Pin Configuration

  • Component Documentation: 470 Ohm Resistor - (Pack of 10)
  • Overview
  • The 470 Ohm Resistor is a passive electronic component used to control the flow of electrical current in a circuit. It is a type of fixed resistor, meaning its resistance value is fixed at 470 Ohms. This pack includes 10 individual resistors, making it a convenient option for various IoT projects.
  • Pinout and Connection Guide
  • The 470 Ohm Resistor has two terminals or pins, which are identical and interchangeable. There is no distinction between the positive and negative terminals, as the resistor is a passive device that does not have polarity.
  • Pin 1: Terminal 1
  • Function: One end of the resistor
  • Connection: Connect to a circuit node or component that requires a resistance of 470 Ohms
  • Note: This terminal is identical to Terminal 2 and can be used interchangeably
  • Pin 2: Terminal 2
  • Function: The other end of the resistor
  • Connection: Connect to a circuit node or component that requires a resistance of 470 Ohms
  • Note: This terminal is identical to Terminal 1 and can be used interchangeably
  • Connection Structure:
  • When connecting the 470 Ohm Resistor in a circuit:
  • 1. Identify the circuit node or component that requires a resistance of 470 Ohms.
  • 2. Connect one terminal (either Pin 1 or Pin 2) to the identified circuit node or component.
  • 3. Connect the other terminal (either Pin 1 or Pin 2) to another circuit node or component that completes the circuit.
  • 4. Ensure the resistor is properly seated and secured in the circuit to prevent damage or electrical shorts.
  • Example Connection Scenario:
  • Suppose you want to connect the 470 Ohm Resistor in a simple LED circuit to limit the current flowing through the LED. You can connect one terminal of the resistor to the positive leg of the LED and the other terminal to the output of a voltage source (e.g., a battery or a microcontroller's output pin).
  • In this example, the 470 Ohm Resistor would be connected as follows:
  • Pin 1 (Terminal 1): Connect to the positive leg of the LED
  • Pin 2 (Terminal 2): Connect to the output of the voltage source (e.g., a battery or a microcontroller's output pin)
  • By following these connection guidelines, you can effectively use the 470 Ohm Resistor in your IoT projects to control current flow and ensure the reliability of your circuits.
