Description

The 150K Ohm 1/2W 5% Through Hole Resistor is a highly reliable component commonly used in electronic circuits to limit current, divide voltage, or filter signals. With a resistance of 150K ohms (150,000 ohms), a power rating of 1/2 watt (0.5W), and a 5% tolerance, this resistor is perfect for moderate power applications. The through-hole mounting design ensures a secure and stable connection to printed circuit boards (PCBs), making it suitable for both prototype development and mass production.

Key Specifications:

• Resistance: 150K ohms (150,000 ohms)

  • The 150K ohm resistor is used in applications that require a higher resistance to control current flow or scale down voltage in a circuit. It's commonly found in voltage divider circuits, signal conditioning, and filtering applications.

• Power Rating: 1/2 watt (0.5W)

  • This resistor can safely dissipate up to 0.5 watts of power, making it ideal for low-to-medium power circuits where the power dissipation is within safe limits.

• Tolerance: ±5%

  • The 5% tolerance means that the actual resistance can vary by 5% from the nominal value. For the 150K ohm resistor, the actual resistance could range from 142,500 ohms to 157,500 ohms.

• Mounting Type: Through-hole

  • The through-hole mounting design allows the resistor's leads to be inserted into holes in the PCB, where they are soldered to form a reliable electrical connection. This mounting method is common for both prototype and mass production circuits.

Applications:

• Current Limiting:
  The 150K ohm resistor is used to limit the current flowing through circuits to protect sensitive components like LEDs, transistors, or microcontrollers from excessive current.

• Voltage Regulation:
  This resistor is used in voltage regulation circuits to help stabilize voltage levels, preventing voltage fluctuations from damaging sensitive components.

• Voltage Divider Circuits:
  The 150K ohm resistor is frequently used in voltage divider circuits, which are designed to reduce voltage levels to safe and usable values for sensors, analog-to-digital converters (ADC), and other measurement systems.

• Signal Processing and Filtering:
  The 150K ohm resistor plays a critical role in signal processing applications, including noise reduction and filtering circuits. It helps stabilize signals in audio amplifiers, radio frequency (RF) circuits, and other systems.

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. However, dimensions may vary slightly based on the manufacturer.

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

Summary:
The 150K Ohm 1/2W 5% Through Hole Resistor is a versatile and reliable component ideal for various electronic applications. With a 150K ohm resistance, 1/2 watt power rating, and 5% tolerance, this resistor is perfect for use in moderate power circuits. The through-hole mounting design ensures easy and secure installation into PCBs, making it suitable for both prototyping and mass production. Whether used for current limiting, voltage regulation, voltage division, or signal processing, this resistor offers consistent and reliable performance across a wide range of electronic circuits.
