The 820K Ohm 1W 5% Through Hole Resistor is a high-precision electronic component designed to limit the current flow in an electrical circuit, ensuring safe and reliable operation of electronic devices. This resistor has a resistance value of 820,000 ohms (820KΩ), which is suitable for various high-resistance applications.

Key Features:

• Resistance Value: 820K ohms (820,000 ohms) – ideal for applications where a high resistance is needed to control current flow without excessive heat generation.
• Power Rating: 1 watt (1W) – this resistor can safely dissipate up to 1 watt of power without risk of damage or overheating, making it suitable for medium-power applications.
• Tolerance: 5% – the resistor is manufactured to provide a tolerance of ±5%, meaning the actual resistance can vary by 5% above or below the nominal value of 820KΩ, allowing for some flexibility in circuit design while still maintaining functionality.
• Through-Hole Design: This resistor features a through-hole design, which is ideal for insertion into holes on a printed circuit board (PCB). The leads of the resistor pass through the PCB and are soldered on the opposite side, ensuring a secure mechanical connection and good electrical conductivity.
• Material and Construction: The resistor is typically made of a ceramic or metal oxide material, offering durability and high thermal stability. The outer coating is usually a flame-retardant epoxy or similar material for protection against environmental factors.
• Size and Form Factor: The size of the resistor is generally in standard 1/4W or 1/2W package sizes, making it compatible with most PCB layouts and easy to integrate into a wide range of electronic projects or devices.

Applications:

The 820K Ohm 1W resistor is commonly used in circuits that require high resistance values, such as:

• Voltage dividers for signal conditioning
• Biasing resistors in amplifiers
• Pull-up or pull-down resistors in digital circuits
• Filtering circuits
• Current-limiting applications

The resistor’s power rating of 1W makes it ideal for use in environments where moderate heat dissipation is required. Its 5% tolerance ensures that it meets general-purpose circuit needs, though for high-precision applications, a resistor with a lower tolerance might be necessary.

Environmental Considerations:

• RoHS Compliant: Many resistors, including this model, are RoHS compliant, meaning they are free from hazardous substances such as lead, cadmium, and mercury, making them safer for the environment and for human handling.
• Operating Temperature Range: This resistor is typically designed to operate in temperatures ranging from -55°C to +155°C, ensuring its reliability in both low and high-temperature environments.

This 820K Ohm 1W 5% Through Hole Resistor is a versatile and reliable choice for various electronic applications, offering an excellent balance of performance, durability, and ease of use in through-hole assembly.
