Are tantalum capacitors safe for use in new designs?
I've heard it suggested that "solid tantalum" capacitors are dangerous and may cause fire, may fail short circuit and are fatally sensitive to even very short over voltage spikes.
Are tantalum ...

Why does the LM1117 data sheet specifically specify tantalum capacitors?
I'm planning on using an LM1117 to regulate 5 V to 3.3 V. Looking at (any of the several) data sheets for the LM1117, they recommend 10 µF tantalum capacitors between input and ground ...

Ceramic (MLCC) versus Tantalum capacitors
From the perspective of an electronics designer, but also taking into account price/cost and social considerations (see Coltan mining and ethics link below), I tend to avoid Tantalum capacitors under ...

Why recommend tantalum over ceramic capacitor for voltage regulator? [duplicate]
The LM1117 voltage regulator datasheet recommends using tantalum capacitors on the input and output. What is the reason for this? What advantage does tantalum have over a ceramic capacitor?
A 10μF ...

Which type of 100nF capacitor is best for 78xx regulator output?
I use 78L12 or similar voltage regulators in a few power supplies. I use them in their basic setup, see the picture:
This diagram is common for all 78xx and 78Lxx regulators. It says that output ...

MAX682 with electrolytic capacitors
In a new design I would like to use the MAX682. In the datasheet I found this typical operating circuit:
I would like to use it exactly like that except that I'm going to pull /SKIP to GND.
In table ...

MLCC vs Tantalum: For Decoupling, input to regulator and ripple reduction
I require a 3.3uf capacitor in a 30 VDC environment for three different purposes:
decoupling of precision ADC or DAC;
input to a regulator (linear, switching, LDO); and
output of any regulator for ...

Voltage rating and tantalum capacitors
I was originally considering using a 10 µF 6.3 V 0603 ceramic capacitor for stabilising the onboard voltage regulator on my microcontrollers. However, it may not be capable because of ...
