Switched power supply capacitors
Lots of electronic hardware gets problems its psu and more specificly: with the electrolytic capacitors.
How do old capacitors usually affect the capacitance of that electrolytic capacitor?
What ...

Maximal operational pressure of tantalum and electrolytic capacitors
I need to design a device that have to operate in an high pressure environment (Nitrogen gas). The operational pressure may vary from 1bar (atmospheric) up to 20..30bar gauge pressure. The regular ...

Could a larger capacitor, at the output of the SMPS, destroy components with larger current draw when its being charged?
I am designing a SEPIC converter using a LT8364 for "power aplications" and a buck converter using a TPS62125 for powering a MCU.
Since I have a bunch (>100pcs) of 100uF, 16V, electrolitic caps ...

SMPS voltage ripple
I'm using the MC34063 for my 35 VDC -> 4VDC SMPS. Here is the circuit (modelled in LTSpice):
Edit: However, using a MC34063 calculator and setting Ipeak = 0.5A,
L1 = 37 uH
C3 = 12.5 uF
Which, ...

MLCC as SMPS filter caps
This question is out of curiosity. I know fairly well that mains SMPS can suffer from bad electrolytic caps. Now I wonder if replacing all electrolytics with MLCCs work? Will it make a more durable ...
