Description

The 4K7 Ohm (4.7K) 1/2W 5% Through Hole Resistor is a widely used electronic component designed to provide specific resistance values in circuits that require current regulation, voltage division, and signal conditioning. With a resistance of 4.7K ohms (4,700 ohms), a power rating of 1/2 watt (0.5W), and a 5% tolerance, this resistor is ideal for use in moderate power applications. The through-hole mounting design ensures easy and reliable integration into printed circuit boards (PCBs), making it suitable for both prototyping and large-scale production.

Key Specifications:

• Resistance: 4.7K ohms (4,700 ohms)

  • The 4.7K ohm resistor is commonly used in circuits that require moderate resistance for controlling current or scaling voltage. It is frequently used in voltage divider circuits, signal conditioning, and filtering applications.

• Power Rating: 1/2 watt (0.5W)

  • With a 1/2 watt power rating, the resistor is capable of dissipating up to 0.5 watts of electrical power without overheating, making it ideal for low-to-medium power circuits.

• Tolerance: ±5%

  • The 5% tolerance means that the actual resistance value can vary by 5% from the nominal value. For the 4.7K ohm resistor, the actual resistance could range between 4,465 ohms and 4,935 ohms.

• Mounting Type: Through-hole

  • The through-hole mounting design allows the resistor's leads to pass through holes in the PCB, where they are soldered to ensure a stable electrical connection. This design is suitable for both prototyping and high-volume manufacturing.

Applications:
