Description

The 6K8 Ohm (6.8K) 1/2W 5% Through Hole Resistor is an essential electronic component designed for various applications requiring resistance, voltage control, and signal conditioning. With a resistance value of 6.8K ohms (6,800 ohms), a power rating of 1/2 watt (0.5W), and a 5% tolerance, this resistor is ideal for low-to-medium power circuits. Its through-hole mounting design ensures easy integration into printed circuit boards (PCBs), making it suitable for both prototyping and large-scale production.

Key Specifications:

• Resistance: 6.8K ohms (6,800 ohms)

  • The 6.8K ohm resistor is typically used in circuits requiring a moderate resistance to control current or scale down voltage. It is commonly found in voltage divider circuits, signal processing, and filtering applications.

• Power Rating: 1/2 watt (0.5W)

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

• Tolerance: ±5%

  • The 5% tolerance means that the actual resistance can vary by 5% from the nominal value. For the 6.8K ohm resistor, the actual resistance could range from 6,460 ohms to 7,140 ohms.

• Mounting Type: Through-hole

  • The through-hole mounting design allows the resistor's leads to pass through holes in the PCB and be soldered to form a secure and stable electrical connection. This mounting style is commonly used in both prototyping and mass production environments.
