The 180K Ohm 1/2W 5% Through Hole Resistor is a highly reliable electronic component used in various circuits for controlling current, voltage division, and filtering signals. With a resistance of 180K ohms (180,000 ohms), a power rating of 1/2 watt (0.5W), and a 5% tolerance, this resistor is ideal for moderate power applications. Its through-hole mounting design ensures a strong and secure connection to printed circuit boards (PCBs), making it suitable for both prototyping and mass production.

Key Specifications:

• Resistance: 180K ohms (180,000 ohms)

  • The 180K ohm resistor is commonly used in circuits requiring higher resistance values to limit current flow or scale down voltage. It's ideal for applications like voltage dividers, signal conditioning, and filtering.

• Power Rating: 1/2 watt (0.5W)

  • This resistor can safely dissipate 0.5 watts of electrical power, making it suitable for low-to-medium power applications where power dissipation is not excessive.

• Tolerance: ±5%

  • The 5% tolerance means the actual resistance value can vary by 5% from the nominal value. For the 180K ohm resistor, the actual resistance could range from 171,000 ohms to 189,000 ohms.

• Mounting Type: Through-hole

  • The through-hole mounting design features metal leads that are inserted through holes in the PCB, ensuring a stable and reliable electrical connection once soldered. This mounting method is commonly used in both prototypes and mass production circuits.

Applications:

• Current Limiting:
  The 180K ohm resistor is ideal for limiting the current in circuits, protecting sensitive components such as LEDs, transistors, and microcontrollers from excessive current flow.

• Voltage Regulation:
  This resistor is used in voltage regulation circuits to help maintain stable voltage levels, ensuring the safe operation of various electronic components and reducing the risk of voltage spikes or fluctuations.

• Voltage Divider Circuits:
  The 180K ohm resistor is frequently used in voltage divider circuits, which are designed to reduce higher voltages to levels that are safe and usable for sensors, analog-to-digital converters (ADC), or other measurement systems.

• Signal Processing and Filtering:
  The 180K ohm resistor is also employed in signal processing and filtering circuits to stabilize and filter signals in systems such as audio amplifiers, radio frequency (RF) circuits, and noise reduction applications.

Physical Characteristics:

• Size:
