I disassembled a LED lamp and it's circuit. My intention is to rebuild that circuit within EveryCircuit app, to understand how it is working.
On this circuit I found two elements that are rising questions to me.
A) I couldn't find a reference for “CY40(0|D)474JE“ To me it looks like a capacitor but it have no idea about the numbers to use?
B) I also found a so-called varistor. I understand that as a variable resistor? But the data sheet that I found did not specify any ohms. The lamp was driven by 230V AC. The lamp's circuit did drive 30 LEDs in series. From my measures I saw 300V DC coming out of the circuit and going to the LEDs.
