Description

The 270K Ohm 1/2W 5% Through Hole Resistor is a high-quality electronic component used in various applications requiring resistance values of 270K ohms (270,000 ohms). With a power rating of 1/2 watt (0.5W) and a 5% tolerance, this resistor is ideal for low-to-medium power circuits. The through-hole mounting type ensures that the resistor provides a reliable and secure connection to printed circuit boards (PCBs), making it suitable for both prototypes and mass production.

Key Specifications:

• Resistance: 270K ohms (270,000 ohms)

  • The 270K ohm resistor is ideal for applications requiring moderate resistance to limit current or scale down voltage. It is commonly used in voltage divider circuits, signal conditioning, filtering, and other electronic designs.

• Power Rating: 1/2 watt (0.5W)

  • The resistor can safely dissipate up to 0.5 watts of electrical power, making it perfect for circuits with moderate power requirements where heat dissipation is manageable.

• Tolerance: ±5%

  • The 5% tolerance means the actual resistance value can vary by 5% from the nominal value. For the 270K ohm resistor, the resistance could range from 256,500 ohms to 283,500 ohms.

• Mounting Type: Through-hole

  • The through-hole mounting design uses metal leads that pass through holes in the PCB, allowing for a secure electrical connection once the leads are soldered. This mounting style is common in both prototype and production PCBs.

Applications:

• Current Limiting:
  The 270K ohm resistor is useful for limiting current in circuits, helping to protect sensitive components such as LEDs, transistors, and microcontrollers from excessive current that could cause damage.

• Voltage Regulation:
  This resistor is commonly used in voltage regulation circuits to maintain stable voltage levels and prevent voltage spikes or fluctuations from affecting sensitive electronic components.

• Voltage Divider Circuits:
  The 270K ohm resistor is a key component in voltage divider circuits, where it helps reduce high voltage levels to lower, safe levels suitable for measurement devices, sensors, and analog-to-digital converters (ADC).

• Signal Processing and Filtering:
  The 270K ohm resistor plays a role in signal processing and filtering applications, helping to stabilize and filter signals in circuits such as audio amplifiers, radio frequency (RF) systems, and noise reduction circuits.

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, though exact dimensions may vary slightly depending on the manufacturer.

• Construction:
  The resistor consists of a cylindrical body with metal leads extending from both ends. These leads pass through holes in the PCB and are soldered to provide a secure, stable connection.

Summary:
The 270K Ohm 1/2W 5% Through Hole Resistor is a reliable and versatile component ideal for use in moderate power applications. With a 270K ohm resistance, 1/2 watt power rating, and 5% tolerance, this resistor is well-suited for voltage regulation, current limiting, voltage division, and signal processing applications.
