A 1M Ohm 1W 5% Through Hole Resistor is a high-precision, passive electronic component designed to limit or regulate the flow of electrical current within a circuit. This resistor has the following key specifications:

1. Resistance Value: 1M Ohm (1,000,000 Ohms) – This is the resistance offered by the resistor to the flow of electric current, measured in ohms (Ω). A 1M Ohm resistor is typically used in circuits that require high resistance values, such as signal processing, sensor circuits, and other high-impedance applications.

2. Power Rating: 1W (1 Watt) – The power rating indicates the maximum amount of electrical power the resistor can dissipate without damage. This resistor is rated for 1 watt, meaning it can safely handle up to 1 watt of power without overheating. Exceeding this rating could lead to thermal damage or failure.

3. Tolerance: 5% – This tolerance percentage represents the possible variation in the actual resistance value compared to the stated 1M Ohm. A 5% tolerance means the resistor could vary between 950,000 Ohms and 1,050,000 Ohms. This level of tolerance is common for general-purpose resistors used in a variety of electronic applications.

4. Through Hole Mounting: This resistor is designed for through-hole mounting, which means it has leads (metallic pins) that are inserted through holes in a printed circuit board (PCB) and soldered to the other side. This makes it suitable for use in conventional electronic assemblies, especially in situations where robust mechanical attachment is needed.

5. Construction: The resistor typically consists of a ceramic or metal-oxide body, providing high stability and durability. The outer coating is usually a flame-retardant material, ensuring the resistor performs well under a wide range of operating conditions.

6. Applications: These resistors are widely used in applications where precision is important, but not critical. They are commonly found in power supplies, voltage dividers, filters, analog circuits, and other general-purpose electronic circuits. Their high resistance value and power rating make them suitable for use in high-impedance circuits or low-current applications.

Overall, a 1M Ohm 1W 5% Through Hole Resistor is a reliable, standard component used in a variety of electronic devices, offering a balance of cost, performance, and versatility for general-purpose electronics.
