Description

The 1 Ohm 1/2W 5% Through Hole Resistor is a standard, general-purpose resistor widely used in various electronic circuits. It has a resistance value of 1 ohm, a power rating of 1/2 watt (0.5W), and a 5% tolerance. Designed for through-hole mounting, this resistor is ideal for use in power circuits, current sensing, and voltage regulation applications.

Key Specifications:

• Resistance: 1 ohm

  • The 1 ohm resistance is often used in circuits that require a low resistance value for current sensing, voltage drop control, or power regulation applications.

• Power Rating: 1/2 watt (0.5W)

  • The resistor can safely dissipate up to 1/2 watt (0.5W) of power, making it suitable for low to moderate power applications that do not require high heat dissipation.

• Tolerance: ±5%

  • The resistance value can vary by up to 5% from the nominal value, meaning the actual resistance could range between 0.95 ohms and 1.05 ohms.

• Mounting Type: Through-hole

  • The through-hole mounting design ensures strong mechanical connections by having metal leads pass through holes in a printed circuit board (PCB), where they are soldered on the opposite side. This type of mounting is ideal for prototyping and assembly in devices that require durable connections.

Applications:

• Current Sensing:
  The 1 ohm resistor is often used in current sensing circuits, where the small voltage drop across the resistor can be measured to determine the current flowing through the circuit.

• Power Regulation:
  It can be used in power supply circuits, voltage regulation, or current limiting applications where maintaining a controlled, low resistance helps ensure efficient energy use.

• Voltage Drop Minimization:
  This resistor is useful for applications where minimizing voltage loss is essential, such as in battery-powered systems or circuits that require high energy efficiency.

• General-Purpose Use:
  With a 1/2 watt power rating and 5% tolerance, it is versatile for use in various general-purpose applications, including amplifiers, signal processing, and voltage or current regulation circuits.

Physical Characteristics:

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

• Construction:
  The resistor is cylindrical with two metal leads that extend from both ends, which are inserted into the PCB and soldered for a secure electrical connection.

Summary:
The 1 Ohm 1/2W 5% Through Hole Resistor is a reliable, low-resistance component used in applications such as current sensing, power regulation, and voltage drop minimization. Its 1/2 watt power rating and 5% tolerance make it a versatile component for various low-power circuits. The through-hole design ensures durability and reliability in both prototype and final circuit designs.
