A capacitive dropper is one simple method used in some transformerless power supply circuits. In this method a capacitor is connected in series with the AC supply to limit the current going into the circuit. This calculator helps us to find the theoretical capacitor value according to the input AC voltage and required current. Capacitive […]

LM567 IC Calculator Tool
We can use this small LM567 calculator tool for finding the right frequency, Rt, and Ct values for our tone decoder circuit. Now we know that this IC works on one simple relation which is, f = 1 / (1.1 × Rt × Ct) So we can see that this frequency depends only on the […]
