The 470K Ohm 1/2W 5% Through Hole Resistor is a high-quality and reliable electronic component used in applications requiring higher resistance values. With a 470K ohm (470,000 ohms) resistance, a 1/2 watt (0.5W) power rating, and a 5% tolerance, this resistor is suitable for moderate power circuits where current and voltage regulation are essential. The through-hole mounting design ensures easy integration into printed circuit boards (PCBs) for secure and stable connections, making it ideal for both prototyping and mass production.

Key Specifications:

• Resistance: 470K ohms (470,000 ohms)

  • The 470K ohm resistor is used in circuits where high resistance is required to control the flow of current or to divide voltages. It's commonly found in signal processing, voltage regulation, and voltage divider applications.

• Power Rating: 1/2 watt (0.5W)

  • With a power rating of 0.5W, the resistor can safely dissipate moderate amounts of power without causing excessive heat buildup, making it suitable for circuits with moderate power demands.

• Tolerance: ±5%

  • The 5% tolerance means that the actual resistance value may vary by 5% from the nominal value. For the 470K ohm resistor, the actual resistance could range from 446,500 ohms to 493,500 ohms.

• Mounting Type: Through-hole

  • The through-hole mounting design features metal leads that are inserted into holes on the PCB and soldered in place, ensuring a secure and stable electrical connection. This type of mounting is widely used in both prototype and production circuits.

Applications:

• Current Limiting:
  The 470K ohm resistor is ideal for current-limiting applications, protecting sensitive components like LEDs, transistors, and microcontrollers from excessive current that could damage them.

• Voltage Regulation:
  This resistor is used in voltage regulation circuits, where it helps maintain stable voltage levels and prevents excessive voltage from reaching sensitive components in the system.

• Voltage Divider Circuits:
  The 470K ohm resistor is commonly used in voltage divider circuits to reduce input voltages to lower levels that can be safely measured or processed by sensors, ADCs (analog-to-digital converters), and other devices.

• Signal Processing and Filtering:
  The 470K ohm resistor is also used in signal processing and filtering applications, where it helps to stabilize and filter signals in audio systems, radio frequency (RF) circuits, and noise reduction circuits.

Physical Characteristics:

• Size:
