Use 3 or more 150W halogen tubes in series as charging R's and ensure Cap charging current is not exceeded. This will give the fastest charging rate. The cold resistance will be 1/10 of hot. If too …

Capacitor internal resistance affects size, cost , peak current, temperature range This "series" is the effective series resistance or ESR. … Capacitor design from OEM's over the last few decades was driven to reduce ESR at low cost and high reliability. …

Wrap your neurons around these scope traces. This should clear it up. Then change all the generator properties to SIN. Try a sawtooth. Then drag and stretch the endpoints to make it an integrator …

You applied a Step Input which has a broad continuous spectrum, thus the C divider is very effective, initially. But over time, unlike a battery in which many orders of magnitude higher capacitance t …

It looks like a line transient "smoked" the MOV and should have blown the fuse too. Here is a list of potential replacements.

No. It takes more than a MOSFET to control phase and timing of ignition pulses. http://ww1.microchip.com/downloads/en/AppNotes/00001980C.pdf http://www.microchip.com/wwwAppNotes/AppNotes.aspx?appno …

I once experienced hiss from pseudo random oscillations in the boost regulator ceramic coil being driven any a buck regulator. So it was PWM fixed f driving a PFM variable f boost regulator. The t …

This trick circuit uses a failure mode of Vce reverse voltage > -5V to conduct up to 5mA at some threshold then go into Avalanche mode and discharge the capacitor to near -5V when the holding current of … The LED series R must not exceed the 5mA tigger current much as the energy discharge from the capacitor can burn out the Vec junction. …

KAM appears to be a Korean supplier of superCaps and yes it is 400 Farads. These are used for backup so they have a fairly high ESR. If they are not matched identically upon charging, the voltage wil …

Much more important than the location of the 0.1uF capacitor is the equivalent series resistance (ESR) of all decoupling capacitors as well as the equivalent series inductance (ESL). … When the distance is too far you are essentially adding ESL and ESR to the capacitor and also radiating the ground loop near other circuits and thus injecting ground spikes. …

Remove all and replace with "lowest" ESR ceramic caps of same value from Murata or TDK at Digikey or equiv. Tolerance is not as important as having them matched from same batch when low ESR is concer …

digi-key is your friend. Also if tight space write down case dia. [mm]. YOu can always make it fit or use larger value or voltage. Low ESR is best in every case. My link is pre-set to low ESR. …
