Description

A 1MΩ 1/4W 1% Through Hole Resistor is an electronic component designed to provide a precise level of resistance in various circuit applications. Here’s a detailed description of its features:

• Resistance Value: The resistor has a resistance of 1 megohm (1MΩ), which means it resists the flow of electrical current at a level of 1 million ohms. This resistance value is commonly used in a variety of electronic circuits, from signal processing to voltage dividers, and is particularly effective for high-impedance applications.

• Power Rating: The resistor is rated for a power dissipation of 1/4 watt (0.25W). This means it can safely dissipate a maximum of 0.25 watts of power without overheating or getting damaged. It's important to select a resistor with the appropriate power rating to ensure long-term reliability and safety in the circuit.

• Tolerance: With a 1% tolerance, this resistor’s actual resistance will not vary by more than 1% from its nominal value of 1MΩ. This high level of precision makes it suitable for applications where accurate resistance is critical, such as in measurement equipment, high-precision sensors, or other circuits requiring tight performance specifications.

• Form Factor: The resistor features a through-hole design, meaning it has leads that pass through the PCB (printed circuit board) and are soldered onto the opposite side. This makes it easy to integrate into traditional electronic designs, particularly for prototyping or in applications where reliability and ease of soldering are important.

• Material and Construction: Typically, these resistors are made from materials such as carbon film, metal oxide, or metal film, providing durability and stability under normal operating conditions. The composition contributes to the resistor’s low noise and reliability over time.

• Applications: This 1MΩ resistor is commonly used in various electronics, including but not limited to:

  • Voltage dividers: To reduce voltage levels in circuits.
  • Signal processing: To limit current and protect sensitive components.
  • Feedback loops in amplifiers: Ensuring correct operation and stability.
  • Consumer electronics: For controlling the flow of current in devices like radios, TVs, or sensors.

• Physical Size: The resistor typically comes in a standard 1/4 watt size, making it compact enough to fit into most electronic devices without taking up excessive space.

This resistor is widely available, cost-effective, and crucial for ensuring the proper operation of various electronic systems. It combines precision, reliability, and ease of use for a broad range of applications.
