Description

The 820K Ohm 1/4W 5% Through Hole Resistor is an electronic component designed to provide a specific resistance value in various electronic circuits. Here’s a detailed breakdown of its features and characteristics:

1. Resistance Value: The resistor has a resistance of 820K ohms, which means it limits the flow of electrical current through it to 820,000 ohms. This value is commonly used in high-impedance applications, signal conditioning, or for setting bias points in analog circuits.

2. Power Rating: With a power rating of 1/4 watt (0.25W), this resistor can safely dissipate up to 0.25 watts of electrical power without overheating or being damaged. It is well-suited for low-power applications where only small amounts of heat are generated.

3. Tolerance: The resistor features a 5% tolerance, meaning the actual resistance could vary by up to 5% from the nominal value of 820K ohms. This tolerance level is generally acceptable for most non-precision applications where exact resistance values aren’t critical.

4. Through-Hole Design: This resistor has a through-hole mount construction, which means it is designed to be inserted into holes on a printed circuit board (PCB) and soldered from the opposite side. This makes it compatible with older or through-hole-based PCB designs, offering a strong, reliable connection.

5. Size and Physical Characteristics: Typically, these resistors are housed in a standard axial lead package with two leads for connection, often measuring about 6mm in length and 2mm in diameter. The leads are made of metal, and they extend from either side of the resistor body.

6. Material and Construction: Through-hole resistors like this one are often made from materials such as carbon film, metal film, or thick-film to achieve the desired resistance values. The resistor is typically encapsulated in a non-flammable resin or ceramic casing to protect it and ensure durability in various environmental conditions.

7. Applications: This resistor is commonly used in a variety of general-purpose applications, including:

   • Signal conditioning circuits
   • Voltage dividers
   • Biasing circuits for transistors or operational amplifiers
   • High-impedance load applications
   • Consumer electronics

8. Durability and Reliability: The resistor is designed for use in standard operating conditions and can perform well in a range of temperatures and environments. It can endure some exposure to environmental factors like humidity, making it reliable for long-term use in various devices.

This 820K Ohm 1/4W 5% Through Hole Resistor is an essential component for many electronic designs, offering a cost-effective, reliable way to manage current and voltage in a wide range of applications.
