Recently a member of TDK-Lambda’s technical marketing team experienced first-hand just how much influence small diameter electrolytic capacitors can have on long-term power supply reliability.

Fig. 1: Spurious emissions seen on the exciter RF output. One of the biggest hassles in maintaining older equipment is getting it repaired when it fails. A lot of companies don’t even want to deal ...

With the increasing penetration of renewable energy, especially due to the instability of wind and solar power, the role of energy storage systems in balancing grid supply and demand and mitigating ...

The electrification trend in the automotive sector shows no signs of abating, and electrolytic capacitors have proved to be a reliable source of high-density power delivery in electric vehicles (EVs).

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 ...

Several years ago I worked on a few designs for LED light bulbs. Very early on it became clear that the temperatures of components in such light bulbs can get quite high. I personally measured ...

Workbench contributor and engineer Duke Evans writes that he has repaired many a circuit board trace with bare wire. In his years of circuit board repairs, Duke has also noted that some older ...

Supercapacitors possess a high cycle efficiency (more than a million cycles), a large number of charging cycles higher than ...

Having acquired some piece of old electronic equipment, be it a computer, radio, or some test gear, the temptation is there to plug it in as soon as you’ve lugged it into the ‘shop. Don’t be so hasty.
