Description

Technical Description

The 1M ohm resistor is an electronic component used to limit current and divide voltage in electronic circuits. This type of resistor is particularly useful in projects that require a high resistance value. The resistor is available in a quantity of 50 pieces, with a nominal power rating of 1/4 watt and a tolerance of 5%. The resistor is suitable for use with various electronic systems, including Arduino-based projects.

The 1M ohm resistor can be used for various purposes, such as protecting LEDs or sensors, creating voltage divider circuits, and creating current limiting circuits. The resistor is available in a standard container, suitable for mounting on printed circuit boards or for use in a laboratory.

To use the 1M ohm resistor, it is necessary to connect it correctly to the electronic circuit. It is important to verify that the resistor is capable of handling the current and voltage of the circuit without exceeding the power limits. The resistor can be used in combination with other electronic components to create more complex circuits.
