This simple calculator will help you determine the value of any SMD resistor. To get started, input the 3 or 4 digit code and hit the "Calculate" button or Enter. Note: The program was tested rigorously, but it still may have a few bugs.
The calculator above will display the value, the tolerance and performs a simple check to verify if the calculated resistance matches one of the EIA standard values. Select the first 3 or 4 bands for 20%, 10% or 5% resistors and all 5 bands for precision (2% or less), 5-band resistors.
28 paź 2022 · You then use an LED resistor calculator the find the value of the resistor. The resistor value is 7.5Ω for 60 mA and a 2.85 V f powered by a 3.3V source, Source: Hobby Hour LED Series Resistor Calculator
Use this tool to calculate the resistance required to drive one or more series-connected LEDs from a voltage source at a specified current level.
This LED calculator will help you design your LED array and choose the best current limiting resistors values. To get started, input the required fields below and hit the "Design Circuit".
This calculator will help you determine the value of the resistor to add in series with the LEDs to limit the current. Just input the indicated values and press the "Calculate" button. As a bonus, it will also calculate the power consumed by each LED.
