The through-hole mounting design makes it easy to integrate into printed circuit boards (PCBs), ideal for both prototyping and mass production environments.

Key Specifications:

• Resistance: 1,000 ohms (1K)

  • The 1K ohm resistance value is commonly used in many types of circuits, including voltage dividers, current-limiting circuits, and signal conditioning applications. It is ideal for circuits where moderate current regulation is required.

• Power Rating: 1/2 watt (0.5W)

  • This resistor is rated to safely dissipate 1/2 watt (0.5W) of electrical power without overheating. This power rating is suitable for low-to-medium power circuits, ensuring optimal performance within its rated limits.

• Tolerance: ±5%

  • The 5% tolerance means that the actual resistance value can vary by up to 5% from the nominal value. For a 1K ohm resistor, the actual resistance can range between 950 ohms and 1,050 ohms.

• Mounting Type: Through-hole

  • The through-hole mounting type allows the resistor's leads to be inserted through holes in a PCB, where they are soldered into place, forming a stable and secure electrical connection. This mounting style is commonly used for both prototype and production applications.
