The 2K7 Ohm (2.7K) 1/2W 5% Through Hole Resistor is a standard and reliable electronic component that is commonly used in a variety of circuits requiring precise current control, voltage division, and signal conditioning. With a resistance of 2.7K ohms (2,700 ohms), a power rating of 1/2 watt (0.5W), and a 5% tolerance, this resistor is ideal for applications where moderate power and accuracy are required. The through-hole mounting design ensures secure and easy integration into printed circuit boards (PCBs).

Key Specifications:

• Resistance: 2.7K ohms (2,700 ohms)

  • The 2.7K ohm resistor is commonly used in circuits that need to regulate current or divide voltage. It is ideal for applications that involve moderate resistance values, such as power regulation, filtering, and signal conditioning.

• Power Rating: 1/2 watt (0.5W)

  • With a 1/2 watt power rating, this resistor is designed to dissipate up to 0.5 watts of electrical power without risk of overheating, making it suitable for circuits with low-to-medium power requirements.

• Tolerance: ±5%

  • The 5% tolerance means that the actual resistance can vary by 5% from the nominal value. For the 2.7K ohm resistor, the actual resistance can range between 2,565 ohms and 2,835 ohms.

• Mounting Type: Through-hole

  • The through-hole mounting design allows the resistor's leads to pass through holes in a PCB, where they are soldered to create a stable and secure electrical connection. This mounting type is commonly used in both prototyping and large-scale production.

Applications:

• Current Limiting:
  The 2.7K ohm resistor is often used in current-limiting applications, such as protecting LEDs or other sensitive components by ensuring that only a safe amount of current flows through them.

• Voltage Regulation:
  This resistor is commonly used in voltage regulation circuits to help maintain a consistent voltage across various components by controlling the amount of current flowing.

• Voltage Divider Circuits:
  The 2.7K ohm resistor is widely used in voltage divider circuits, which are used to scale down voltage levels for sensors, ADCs (Analog-to-Digital Converters), or other measurement systems.

• Signal Processing and Filtering:
  It is also used in signal processing, filtering, and noise reduction applications in audio circuits, RF systems, and other signal conditioning applications.

Physical Characteristics:

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

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