Description

The 330 Ohm 1/2W 5% Through Hole Resistor is a widely used electronic component that offers a resistance of 330 ohms, a power rating of 1/2 watt (0.5W), and a 5% tolerance. It is ideal for applications that require current limiting, voltage regulation, and signal conditioning. The through-hole mounting ensures a stable and reliable connection to printed circuit boards (PCBs), making it suitable for both prototyping and mass production.

Key Specifications:

• Resistance: 330 ohms

  • The 330 ohm resistance value is commonly used for controlling the current flow in a variety of circuits, including power supply systems, LED circuits, voltage dividers, and signal conditioning applications.

• 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 well-suited for low-to-medium power circuits.

• Tolerance: ±5%

  • The 5% tolerance indicates that the actual resistance can vary by up to 5% from the nominal value. For the 330 ohm resistor, the actual resistance could range from 313.5 ohms to 346.5 ohms.

• Mounting Type: Through-hole

  • The through-hole mounting design allows the resistor's leads to be inserted through holes in the PCB. The leads are then soldered in place, ensuring a stable and durable electrical connection. This mounting type is ideal for both prototyping and production applications.

Applications:

• Current Limiting:
  The 330 ohm resistor is commonly used in circuits where current limitation is necessary, such as in LED circuits, where it helps to prevent excessive current that could damage the LEDs.

• Voltage Regulation:
  This resistor is often used in voltage regulation circuits to help control the flow of current and maintain a stable voltage across various components in the system.

• Power Distribution:
  The 330 ohm resistor is suitable for power distribution systems, helping to regulate the flow of current and voltage to prevent overloading components and ensuring stable operation.

• Signal Processing and Filtering:
  This resistor is also used in signal processing applications, where it helps in filtering signals, reducing noise, and stabilizing voltage levels in circuits such as audio amplifiers, RF (radio frequency) systems, and sensor circuits.

Physical Characteristics:

• Size:
  A 1/2 watt resistor typically measures around 1/4 inch (6.35 mm) in length and 1/8 inch (3.18 mm) in diameter, although the exact dimensions may vary slightly depending on the manufacturer.

• Construction:
  The resistor features a cylindrical body with metal leads extending from each end. These leads pass through the PCB holes and are soldered to form a secure electrical connection.
