4.7K ohm Resistor 4700 ohm 1/4w 5%

Description

Technical Description

The 4.7K ohm resistor is an essential component for electronic projects, particularly those based on Arduino. It is mainly used to limit the flow of current and protect sensitive circuits from current overloads. The resistor has a 5% tolerance and a power dissipation capability of 1/4 watt, making it suitable for moderate applications.

The resistor is used in series with other components, such as LEDs or sensors, to regulate the current intensity flowing through them. It is important to verify the value of the resistor and its tolerance before using it in the circuit to ensure it functions correctly without overloading the component.

The 4.7K ohm resistor is available in quantities of 50 pieces to facilitate the realization of large-scale electronic projects.
