Resistor / Power Calculator
Supply voltage : V
Operating voltage of the LED component : V
Operating intensity of the LED component : mA
Value of the resistor to use : Ohms
Recommended power : W

    • How to use the board ?

To obtain the value of the wanted resistor, you need to fill the boxes with your own values and the resistor and power boxes will fill up on their own !


  • Supply voltage

This voltage is what feeds your entire circuit like a battery, a power supply,... you have to fill it with your own info, meaning which supply power voltage you want to feed your LED with. It has nothing to do with what you could find on the website !



  • Operating voltage of the LED component


This value is on the product datasheet of every LED component.



  • Operating intensity of the LED component


This value is on the product datasheet of every LED component



  • Real resistor

This value gives you the ideal resistor value for your circuit. You just need to choose the closest superior resistor.



  • Power

This value is necessary to choose the right resistor on the website. For instance, if the indicated value is 0.17 watt, it means you need a 1/4 watt resistor. You have to choose the closest value from what is recommended in the board.

Toujours pas livré!

déjà deux semaines de retard sur la livraison initiale(commande passée le 23/03/20) et je ne suis toujours pas livré(on m'annonce sans certitude le 14/04/20)! Bizarrement quand on regarde les commentaires, tout le monde est livré normalement... C'est ma première commande sur ce site et surement la dernière!!! PlaneteLeds : Nous sommes navrés pour le retard que prend votre commande. Nous sommes, comme toutes les entreprises de France prises de cours par la situation actuelle et rencontrons de grosses difficultés à être réapprovisionnés sur certaines de nos références. Nous faisons notre maximum pour diminuer votre temps d'attente.
