Digikey led resistor calculator. This tool is used to calculate power current voltage or resistance. 2 likes simple blinking led circuit. Optoelectronics ship same day. Optoelectronics led indication discrete are in stock at digikey.

To get started input the required fields below and hit the design circuit. Digi key also has a separate ohm s law calculator for the customer convenience. This led calculator will help you design your led array and choose the best current limiting resistors values. Led resistor calculator to calculate the resistor needed for a simple led circuit simply take the voltage drop away from the source voltage then apply ohm s law.

This tool is designed to find the resistance and tolerance values of through hole resistors. If the length of the trace is also provided the total resistance voltage drop and power loss due to trace resistance are also calculated. To help simplify the process digi key has an led series resistor calculator that will calculate you required resistance and power ratings for your led circuit. Led series resistor calculator.

Digi key s tools are uniquely paired with access to the world s largest selection of electronic components to help you meet your design challenges head on. The power source you are using to power up your leds in volts. This tool uses formulas from ipc 2221 to calculate the width of a copper printed circuit board conductor or trace required to carry a given current while keeping the resulting increase in trace temperature below a specified limit.
