Description

The 10M Ohm (10,000,000 ohms) 1/2W 5% Through Hole Resistor is a high-resistance, general-purpose resistor designed for use in electronic circuits where precise control of current and voltage is necessary. With a nominal resistance of 10M ohms, a 1/2 watt (0.5W) power rating, and a 5% tolerance, this resistor is ideal for circuits requiring moderate power handling. Its through-hole mounting design ensures a secure attachment to printed circuit boards (PCBs), making it suitable for both prototyping and production-level applications.

Key Specifications:

• Resistance: 10M ohms (10,000,000 ohms)

  • The 10M ohm resistor is used in high-impedance circuits where high resistance is required to limit current flow, divide voltages, or stabilize signals. It is commonly found in voltage dividers, sensor circuits, and circuits requiring very high resistance values.

• Power Rating: 1/2 watt (0.5W)

  • This resistor is designed to handle up to 0.5 watts of power dissipation. It is suitable for moderate-power applications where power needs to be dissipated safely without the risk of overheating.

• Tolerance: ±5%

  • The 5% tolerance means that the actual resistance can vary by 5% from the nominal value. For the 10M ohm resistor, this means the actual resistance could range from 9.5M ohms to 10.5M ohms.

• Mounting Type: Through-hole

  • The through-hole mounting design uses metal leads that pass through holes in the PCB and are soldered in place, creating a stable and secure electrical connection. This mounting type is widely used in both prototype and mass-production electronics.

Applications:

• Current Limiting:
  The 10M ohm resistor can be used to limit current in circuits, preventing components from receiving excessive current that could lead to damage. This is especially important in circuits with sensitive devices such as microcontrollers and LEDs.

• Voltage Regulation:
  It is commonly used in voltage regulation circuits, where it helps control voltage levels and prevent spikes that could damage other components. The high resistance helps to maintain steady voltages in sensitive circuits.

• Voltage Divider Circuits:
  The 10M ohm resistor is often used in voltage divider applications to reduce higher input voltages to lower, more manageable levels. It is paired with other resistors to create specific output voltages that can be used for sensor readings or other analog measurements.

• Signal Processing and Filtering:
  This resistor is valuable in signal processing circuits where high impedance is needed, such as in filtering applications. It helps stabilize and process electrical signals, ensuring accurate results in audio, RF (radio frequency), and analog signal applications.

Physical Characteristics:

• Size:
  As a 1/2 watt resistor, it typically measures about 1/4 inch (6.35 mm) in length and 1/8 inch (3.18 mm) in diameter, although the dimensions can vary slightly depending on the manufacturer.

• Construction:
  The resistor features a cylindrical body with metal leads extending from each end. These leads are inserted through holes on the PCB and soldered into place, providing a reliable electrical connection.

Summary:
The 10M Ohm (10,000,000 ohms) 1/2W 5% Through Hole Resistor is a high-value, general-purpose resistor ideal for use in high-impedance circuits. With its 10M ohm resistance, 1/2 watt power rating, and 5% tolerance, it is perfect for current-limiting, voltage regulation, voltage divider circuits, and signal processing applications. The through-hole mounting ensures a stable connection to PCBs, making it ideal for both prototyping and large-scale manufacturing. This resistor delivers dependable performance in circuits that require high resistance, contributing to the safe and efficient operation of electronic systems.
