Detailed Information

The 10 ohm resistor strikes a balance between low resistance and manageable power dissipation. It's commonly used in digital circuits for pull-down applications, current limiting for LEDs in high-voltage systems, and as a base resistor in transistor circuits. Its moderate resistance value makes it suitable for applications where you need to limit current without creating significant voltage drops.

💡 Pro Tips

  • Good choice for pull-down resistors in 5V systems
  • Check power rating when used for current limiting
  • Consider using 1% tolerance for precision applications
  • Suitable for most general-purpose low-resistance needs
