Description

A 1MΩ (1 Megaohm) 1/4W 5% Through Hole Resistor is a type of passive electronic component used to limit or control the flow of electrical current in a circuit. Here is a detailed description of its specifications:

• Resistance Value: The resistor has a resistance of 1 Megaohm (1MΩ), meaning it resists the flow of electrical current by 1 million ohms. This high resistance value makes it ideal for use in circuits where a large resistance is needed to control the current or to provide a voltage drop.

• Power Rating: The resistor has a power rating of 1/4 watt (0.25W). This indicates the amount of power the resistor can dissipate without being damaged or overheating. A 1/4W rating is common for many general-purpose resistors used in low-power applications.

• Tolerance: This resistor has a tolerance of 5%, which means the actual resistance can vary by ±5% from the nominal value of 1MΩ. For example, the resistance could be anywhere between 950kΩ and 1.05MΩ. A 5% tolerance is typical for non-precision resistors used in general applications.

• Type: It is a Through Hole Resistor, meaning it is designed to be inserted into a hole on a printed circuit board (PCB) and soldered in place. This type of resistor is commonly used in traditional electronic assemblies and offers a secure connection to the circuit.

• Construction: The resistor is typically made of a metal oxide or carbon film material that provides the resistance. The body is cylindrical, often with color-coded bands indicating the resistance value and tolerance.

• Applications: A 1MΩ 1/4W 5% through-hole resistor is suitable for a wide range of general-purpose applications, including signal conditioning, voltage dividers, pull-up or pull-down resistors, and high-impedance circuits. It can be used in various consumer electronics, automotive, industrial, and communication systems.

This resistor is widely used due to its balance of cost, reliability, and availability in most standard electronic circuit designs.
