Today, 07:38KlausST replied to a thread Crystal Oscillator issue in Professional Hardware and Electronics DesignHi, Mind: datasheets show the circuit how it should be. Most datasheets are correct, thus - if the circuit doesnīt work - there may be a problem...7 replies | 337 view(s) -
Today, 06:03KlausST replied to a thread transformer constantly steps down in LTSPICE in Elementary Electronic QuestionsHi, I didn't check the series resistances. But with a L1/L2 ratio of 30/300, I expect a coupling factor of sqrt(300/30)...which is about 3.16....4 replies | 84 view(s)

13th July 2018, 16:54KlausST replied to a thread Using irf2110 IC for bldc motor control for low speed application in Elementary Electronic QuestionsHi, I don't know what "30-5- RPM" means... but usually the RPM has nothing to do with IR2110. What counts is: *switching frequency * duty...8 replies | 353 view(s)

12th July 2018, 08:07KlausST replied to a thread cant make sense of current, voltage, resistance relationship, graph in Analog Circuit DesignHi, Post#1 I agree the graph doesn't make much sense. There is Ohm's Law. R = V / I And it says "constant voltage" Let's calculate some...6 replies | 195 view(s)
