Its through-hole mounting design ensures secure and reliable integration into printed circuit boards (PCBs), making it suitable for both prototyping and mass production.

Key Specifications:

• Resistance: 10K ohms (10,000 ohms)

  • The 10K ohm resistor is a versatile component used in circuits where a higher resistance is needed to control current flow or scale voltage. It is commonly used in voltage divider circuits, signal conditioning, and current-limiting applications.

• Power Rating: 1/2 watt (0.5W)

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

• Tolerance: ±5%

  • The 5% tolerance means that the actual resistance can vary by 5% from the nominal value. For the 10K ohm resistor, the actual resistance could range from 9,500 ohms to 10,500 ohms.

• Mounting Type: Through-hole

  • The through-hole mounting type allows the resistor’s leads to pass through holes in the PCB and be soldered to form a secure electrical connection. This mounting style is popular for both prototype designs and mass production.
