50 Pack 3.0K Ohm Resistor 3000 Ohm 1/4W 5%

Description

Technical Specifications

The 3.0K ohm resistor is an electronic component used to limit the flow of current in a circuit. This type of resistor is commonly used in electronic projects to protect sensitive components such as LEDs and transistors from excessive current. The 3.0K ohm resistor offers a 5% tolerance and a maximum power rating of 1/4 watt, making it suitable for applications that do not require significant heat dissipation.

To use this resistor, it is necessary to connect it correctly in series with a component that requires current limitation, such as an LED. It is important to verify that the resistor is properly calculated to protect the electronic component without excessively limiting the necessary current flow.

The 3.0K ohm resistor is a fundamental component for electronic prototyping projects, testing, and applications where it is necessary to limit the current to protect the components.
