5 Real-World Capacitor Applications & Micro Teardowns - DC To Daylight

In this episode, Derek discusses 5 different real-world capacitor applications: 1. Linear power supplies, 2. AC-Coupling / DC-blocking, 3. Bypass Capacitors, 4. Condenser Microphone Capsules, and 5. Decoupling Capacitors. Derek spares you the math in this video, and instead shows you an overview of each schematic, followed by a micro teardown and a couple of measurements at the same time. If you like to take things apart, this episode is for you!

@17:30 The enemy of low level signals is _moisture, _ and that's the reason for the conformal coating. Moisture (as from a speaker/singer's breath) can cause stray capacitance changes at the board traces, and over time causes component values to drift. Of course, grit and grime don't help, and do collect even more moisture.

When used as bypass capacitor (as seen on the schematic), does the capacitor "bypasses" that one resistor in between its terminals at high enough frequency, changing the gain?

awesome video thanks Derek, for the details, indeed, you are well understood

[GeoffryGifari]

if there is a sudden change in voltage from the mains (like when the circuit breaker suddenly turns off the electricity of a building), what are the mechanisms inside a power supply that prevent our devices from blowing up?

@14:43 It's actually not strange. Many preamps don't supply exactly 48 volts (I've seen 12!) and some are weak enough that several microphones will pull the voltage down. The circuit in your mic ensures the diaphragm gets a stable, pure 48 volts, needed for a stable, noise-free audio signal. Most higher end mics that use phantom power will have a similar circuit.

ELEMENT, I would like to see the formulas used to get the filter capacitor values in power supplies, I have been told that reservoir capacitors are large values but are below the 60hz so they don't filter out the 60hz but to store energy while filter capacitors values are at the cut off frequency at 60hz to filter out 60hz. It would be nice to show the formulas to compute to get that ripple AC voltage and filter capacitor values.

Great as usual from DC to star's light 😊

Are you fan of donut media? Derek? .. i am big fan too

[PapasDino]

Nice video Derek...I'm curious about how you found out about your EME power limitation issue...are you near some kind of exclusion zone/military facility etc.? 73 - Dino KLØS

Up to speed...capacitors
