LED calculatorThis is the new version of the single LED series resistance calculator, good for when you have a single LED and need to know "what resistor should I use with my LED?" This calculator determines that for you. The LED series/parallel array wizard is available for those of you who need to do calculations involving more than one LED. The wizard will help you pick the resistors make the connections for any number of LEDs. LED calculator: current limiting resistor valueThe wizard recommends a 1/8W or greater 8200 ohm resistor. The color code for 8200 ohms is grey red red.

You should actually be able to buy a 5% resistor with the value returned by the calculator. ** Power calculations assume use of the standard value current-limiting resistor shown above. Resistor power ratings are chosen based on operating within 60% of the rated value. LED calculator version 2.0 Copyright 2001-2006, Rob 'linear' Arnold. All rights reserved. |
