Description

The 1MΩ 1/8W 5% Through Hole Resistor is an electronic component designed to provide resistance in circuits with specific electrical characteristics. Here’s a breakdown of its features:

1. Resistance Value (1MΩ): The resistor has a resistance of 1 Megaohm (1MΩ), which is equivalent to 1,000,000 ohms. This value determines the amount of opposition the resistor will provide to the flow of electrical current in the circuit. A higher resistance value, like 1MΩ, is typically used for limiting current or voltage in sensitive applications such as signal conditioning, biasing, or feedback loops.

2. Power Rating (1/8W): The resistor is rated for a maximum power dissipation of 1/8 watt (0.125W). This rating indicates the maximum amount of electrical power the resistor can safely dissipate without overheating or getting damaged. It is suitable for low-power applications, where high current or voltage is not expected to pass through the resistor.

3. Tolerance (5%): The resistor has a tolerance of 5%, which means the actual resistance can vary by 5% higher or lower than the specified value of 1MΩ. This tolerance is typical for general-purpose resistors, offering a balance between cost and precision for many electronic circuits where absolute resistance accuracy is not critical.

4. Package Type (Through Hole): The resistor is designed with through-hole leads, which means it has two metal leads that are inserted into holes on a circuit board. After insertion, the leads are soldered into place, making it a robust option for permanent installations in many consumer electronics, DIY projects, and prototyping. Through-hole resistors are favored for their durability, ease of installation, and higher mechanical strength compared to surface-mount resistors.

5. Applications: This type of resistor is used in a variety of electronic circuits, including power supplies, audio equipment, sensors, amplifiers, and other low-power applications where precise control over current and voltage is required. It is a common component in both analog and digital circuit designs.

6. Construction: The resistor consists of a ceramic or carbon core, with metal film or metal oxide coating providing the resistance. It is often encased in an insulating material, such as a plastic or ceramic sleeve, to protect it from environmental factors like humidity or temperature fluctuations.

7. Durability & Reliability: With a tolerance of 5% and the ability to handle 1/8W of power, this resistor is ideal for applications that require consistent performance under moderate conditions. It is durable, reliable, and built to withstand typical operating conditions for most consumer-grade electronics.

This resistor is an essential component for engineers, hobbyists, and manufacturers working on circuit designs where accurate but not overly precise resistance values are needed, especially in low-power applications.
