Description

The 470 Ohm 1/2W 5% Through Hole Resistor is a reliable and commonly used resistor in various electronic circuits. With a resistance value of 470 ohms, a power rating of 1/2 watt (0.5W), and a 5% tolerance, it is ideal for applications such as current limiting, voltage regulation, and signal conditioning. The through-hole mounting design ensures secure and reliable placement in printed circuit boards (PCBs), making it suitable for both prototyping and mass production.

Key Specifications:

• Resistance: 470 ohms

  • The 470 ohm resistance value is commonly used in circuits where moderate current regulation is required, such as in LED circuits, voltage dividers, and signal processing.

• Power Rating: 1/2 watt (0.5W)

  • This resistor has a 1/2 watt power rating, meaning it can safely dissipate up to 0.5 watts of electrical power without overheating. It is suited for low-to-medium power circuits, ensuring optimal operation within its rated limits.

• Tolerance: ±5%

  • The 5% tolerance means that the actual resistance value can vary by up to 5% from the nominal value. For the 470 ohm resistor, the actual resistance could range from 446.5 ohms to 493.5 ohms.

• Mounting Type: Through-hole

  • The through-hole mounting design allows the resistor's leads to be inserted into holes in the PCB, where they are soldered to form a stable and durable electrical connection. This design is widely used for both prototype development and production assemblies.

Applications:

• Current Limiting:
  The 470 ohm resistor is commonly used in current-limiting applications, especially in circuits with LEDs, to protect components from excessive current that may cause damage.
