Inductors are more like a resistor in series with an ideal inductor, resistors can be inductors as well, and well, capacitors aren’t just simply a capacitance in a package. Little with electronics is ...

Ever wonder what’s inside an electrolytic capacitor? Many of us don’t, having had at least a partial glimpse inside after failure of the cap due to old age or crossed polarity. The rest of us will ...

Panasonic has introduced the ZV Series – an Electrolytic Polymer Hybrid capacitor with advanced characteristics. It achieves a maximum Ripple Current (3.3~4.6 Arms) – claimed to be approximately 50% ...

Panasonic is promising long life from a range of surface-mount aluminium electrolytic capacitors. The parts span 10 – 680µF, 6.3 – 50Vdc and come in radial cases from 6.3mm in diameter and 7.7mm tall ...

This presentation was originally given by Andrew Smith, product manager, LED Lighting at Power Integrations for EDN’s May 2011 live LED event in San Jose. Consumers often see LED lamp failures. If you ...

As we have seen in part I and part II of this series [1], there are no inherent wear-out mechanisms in ceramic capacitors. And yes, as covered in part II, the high dielectric Class 2 capacitors (X7R) ...

With their low equivalent series resistance (ESR), which allows for good ripple-current handling as well as high surge-voltage ratings and self-healing properties, film capacitors are strong ...
