Description

The 33K Ohm 1/2W 5% Through Hole Resistor is an essential component in many electronic circuits, commonly used for current limiting, voltage division, signal processing, and filtering applications. With a resistance value of 33K ohms (33,000 ohms), a power rating of 1/2 watt (0.5W), and a 5% tolerance, this resistor is ideal for moderate power circuits. The through-hole mounting design ensures secure installation into printed circuit boards (PCBs), making it suitable for both prototype and mass production environments.

Key Specifications:

• Resistance: 33K ohms (33,000 ohms)

  • The 33K ohm resistor is commonly used in circuits where a higher resistance is needed to limit current or scale down voltage. It is widely applied in voltage divider circuits, signal conditioning, and filtering 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 the risk of overheating, making it ideal for low-to-medium power applications.

• Tolerance: ±5%

  • The 5% tolerance means the actual resistance can vary by 5% from the nominal value. For the 33K ohm resistor, the actual resistance could range from 31,350 ohms to 34,650 ohms.

• Mounting Type: Through-hole

  • The through-hole mounting design allows the resistor’s leads to be inserted through holes in the PCB and be soldered, ensuring a stable and reliable electrical connection. This type of mounting is commonly used in both prototype designs and large-scale production.
