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

Key Specifications:

• Resistance: 47K ohms (47,000 ohms)

  • The 47K ohm resistor is used in circuits where a higher resistance is required to control current flow or scale down voltage. It is commonly employed 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 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 47K ohm resistor, the actual resistance could range from 44,650 ohms to 49,350 ohms.

• Mounting Type: Through-hole

  • The through-hole mounting design allows the resistor’s leads to pass through holes in the PCB and be soldered, providing a secure and reliable electrical connection. This mounting type is widely used in both prototyping and mass production.

Applications:

• Current Limiting:
  The 47K ohm resistor is frequently used in current-limiting applications to prevent excessive current from flowing through sensitive components such as LEDs, transistors, and microcontrollers.

• Voltage Regulation:
  This resistor is used in voltage regulation circuits to help stabilize voltage levels and protect components by limiting fluctuations in voltage.

• Voltage Divider Circuits:
  The 47K ohm resistor is commonly used in voltage divider circuits, which are used to scale down higher voltage levels to safe levels for use with sensors, analog-to-digital converters (ADC), or other measurement systems.

• Signal Processing and Filtering:
  The 47K ohm resistor is often used in signal processing and filtering applications, helping to stabilize and filter signals in systems such as audio amplifiers, radio frequency (RF) circuits, and noise reduction systems.

Physical Characteristics:

• Size:
