Description

The 1K5 Ohm (1.5K) 1/2W 5% Through Hole Resistor is a reliable and versatile electronic component commonly used for current regulation, voltage division, and signal conditioning in electronic circuits. With a resistance of 1.5K ohms (1,500 ohms), a power rating of 1/2 watt (0.5W), and a 5% tolerance, this resistor is ideal for moderate power applications. The through-hole mounting design ensures that the resistor is securely integrated into printed circuit boards (PCBs), making it suitable for both prototypes and mass-produced electronic products.

Key Specifications:

• Resistance: 1.5K ohms (1,500 ohms)

  • The 1.5K ohm resistor is commonly used in circuits where a moderate level of current limiting is needed or where precise voltage division is required. It is widely used in power regulation, signal processing, and voltage divider networks.

• Power Rating: 1/2 watt (0.5W)

  • With a 1/2 watt power rating, this resistor can safely dissipate 0.5 watts of electrical power without overheating, making it suitable for low-to-medium power circuits.

• Tolerance: ±5%

  • The 5% tolerance means that the actual resistance value may vary by 5% from the nominal value. For the 1.5K ohm resistor, this translates to an actual resistance range of 1,425 ohms to 1,575 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 form a secure electrical connection. This mounting style is commonly used for both prototype development and high-volume manufacturing.

Applications:

• Current Limiting:
  The 1.5K ohm resistor is frequently used in circuits where it is essential to limit the amount of current flowing to sensitive components, such as in LED circuits or protecting electronic components from excessive current.

• Voltage Regulation:
  This resistor is often used in voltage regulation applications to maintain a stable voltage in various parts of a circuit by controlling the flow of current.

• Voltage Divider Circuits:
  The 1.5K ohm resistor is widely used in voltage divider circuits where it helps scale down voltage levels for measurement systems, sensors, or analog-to-digital conversion.

• Signal Processing and Filtering:
  It is used in signal conditioning circuits, audio amplifiers, RF systems, and sensor circuits to reduce noise, stabilize voltage levels, and filter unwanted signals.

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 features a cylindrical body with metal leads extending from both ends. These leads pass through holes in the PCB and are soldered in place to form a stable electrical connection.

Summary:
The 1K5 Ohm (1.5K) 1/2W 5% Through Hole Resistor is a versatile component used in a wide range of applications such as current limiting, voltage regulation, signal processing, and voltage division. With its 1.5K ohm resistance, 1/2 watt power rating, and 5% tolerance, it is ideal for low-to-medium power circuits. The through-hole mounting design ensures a secure connection to PCBs, making it suitable for both prototyping and commercial production. Whether used in LED circuits, voltage regulation systems, or signal processing applications, this resistor provides dependable and consistent performance.
