Most ICs need to be decoupled from their power supply, usually with a 0.1uF capacitor between each power pin and ground. Decoupling is usually used to remove noise and to smooth power fluctuations.

Choosing decoupling-capacitor values can seem to be a “no-brainer.” Unfortunately, even though the consequences of selecting the wrong values are often serious, the most commonly used methods usually ...

Everyone knows that the perfect capacitor to decouple the power rails around ICs is a 100 nF ceramic capacitor or equivalent, yet where does this ‘fact’ come from and is it even correct? These are the ...

Noise management, induced by digital circuits on a p. c. board assembly, deserves the attention of power supply designers and those mastering digital, analog, and mixed-mode application problems ...

Taiyo Yuden is claiming a thinness record for 0.47µF capacitors, with some 0.11mm tall devices for decoupling in phones and wearables. Called PMK105 BJ474ML and PMC105 BJ474ML, they have a 1.0 x 0.5mm ...
