3.3M Ohm Resistor Pack

Description

Technical Specification

The 3.3M ohm resistor is a fundamental component for electronic projects that require current limiting or voltage division. This type of resistor is used to protect sensitive components such as LEDs and to regulate voltage levels in different parts of a circuit. The 3.3M ohm resistor, with a 5% tolerance, ensures a stable and repeatable resistance.

The 3.3M ohm resistor is available in quantities of 50 pieces and has a maximum power dissipation of 1/4 watt. Its high resistance makes it suitable for applications where current needs to be limited to very low levels.

To use the 3.3M ohm resistor correctly, it is important to verify the component specifications and power dissipation. The resistor must be connected correctly relative to the current flow in the circuit and its power dissipation must be kept under control to avoid damage.
