A recent trend in the design of portable devices has been to use ceramic capacitors to filter DC/DC converter inputs. Ceramic capacitors are often chosen because of their small size, low equivalent series resistance (ESR) and high RMS current ...

John Caldwell, Texas Instruments EDN Introduction Multilayer ceramic capacitors (MLCCs) are used extensively in modern electronics because they offer high volumetric efficiencies and low equivalent series resistances at attractive prices. These ...

Panasonic Advanced capacitors based on conductive polymers maximize performance and reliability Hybrid capacitor technology combines the performance benefits of electrolytic and polymer capacitors. Capacitors may seem simple enough, but specifying ...

Adding parts or cutting PCB slots can make a difference Some surface-mount capacitors exhibit acoustic noise when operated at frequencies in the audio range. A recent design uses 10-uF, 35V X5R 1206 ceramic capacitors that produce noticeable ...
