Description

The 270 Ohm 1/2W 5% Through Hole Resistor is a reliable and widely used resistor in electronic circuits. Offering a resistance of 270 ohms, a power rating of 1/2 watt (0.5W), and a 5% tolerance, this resistor is ideal for applications where moderate current limiting, voltage regulation, and signal conditioning are required. Its through-hole mounting ensures a secure and stable connection to printed circuit boards (PCBs), making it suitable for both prototyping and production environments.

Key Specifications:

• Resistance: 270 ohms

  • The 270 ohm resistance value is commonly used in circuits that require current limiting, voltage division, or controlling current flow in a controlled manner to prevent damage to other components.

• Power Rating: 1/2 watt (0.5W)

  • The 1/2 watt power rating ensures that this resistor can safely dissipate up to 0.5 watts of power without risk of overheating, making it suitable for low-to-medium power applications.

• Tolerance: ±5%

  • The 5% tolerance means that the actual resistance value can vary by up to 5% from the nominal value. For the 270 ohm resistor, the actual resistance can range from 256.5 ohms to 283.5 ohms.

• Mounting Type: Through-hole

  • The through-hole mounting design allows for easy insertion of the resistor's leads through holes in the PCB. These leads are soldered in place to provide a reliable electrical connection. This style is widely used for both prototyping and mass production.

Applications:

• Current Limiting:
  The 270 ohm resistor is commonly used to limit current flow through sensitive components, such as LEDs and transistors, preventing them from being damaged by excess current.

• Voltage Regulation:
  This resistor is frequently used in voltage regulation circuits, helping to control the flow of current and maintain a stable voltage level across various parts of the circuit.

• Power Distribution:
  The 270 ohm resistor is ideal for power distribution systems, ensuring proper voltage and current levels are delivered to each component in the circuit without overloading the system.

• Signal Processing and Filtering:
  This resistor is used in signal conditioning and filtering circuits, helping to reduce noise, smooth signals, and stabilize voltage in applications such as audio amplification, RF systems, and sensor-based 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 exact dimensions may vary slightly depending on the manufacturer.

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

Summary:
The 270 Ohm 1/2W 5% Through Hole Resistor is a versatile and reliable component for various electronic applications.
