1) The saturation current value (Idc1) is the DC current having inductance decrease down to 30% (at 20 dec C). If you exceed this, the inductor will saturate and the current will rise sharply … . You want to avoid this or your design won't work as expected. 2) The temperature rise current value (Idc2) is the DC current value having temperature increase by 40 deg C (at 20 deg C). If …

Assuming that you are using this as a switch and not in linear mode ... The collector current is only rated for 30 mA absolute max, so you can't get 50 mA on the output. You either need to pick …

Alkaline or NiMH AA batteries are certainly OK at 121 mA. The current draw in a speedlight/photoflash is higher than this based on the big cap charge time. 4 AA batteries can charge a 1000 uF, 300V …

A perfect negative resistor is impossible, but a device can have negative resistance characteristics over a limited range. The resistance of a non-linear device varies and at a given voltage the equ …

The resistor in series with the source isn't allowing the MOSFET to turn on completely, you need to move the resistor in series with the source to the top, in series with the LED.
