Supercapacitors bridge the gap between electrolytic capacitors and batteries, delivering high power density with very long cycle life.

Recent developments

• Higher energy density: new carbon and electrolyte chemistries are pushing energy density toward battery territory.
• Hybrid devices: lithium-ion…

Common mode chokes are essential for suppressing common-mode EMI in power lines, data interfaces and automotive networks.

How they work

A common mode choke consists of two windings on a single magnetic core. Differential currents cancel magnetically, while common-mode currents add and encounter hi…
