Epcos AG – Capacitors EMC SAW Components

“SAW components (surface acoustic wave components), integrated radio frequency modules are key components of modern information and communications.”

TDK Corporation has extended its range of EPCOS power factor controllers. The new BR7000-I controller is designed specifically for single-phase networks and combines all the performance features and functions of the proven BR6000 series with the benefits of the BR7000 controller.

Power factor correction Controllers Epcos

The controller has 12 or 13 outputs. The message and alarm relay parameters may be programmed to open or close.

Technical Papers of Evans Capacitor

The Littlest Big Capacitor – An Evans Hybrid – Presented at the Fifth International Seminar on Double Layer Capacitors and Similar Energy Storage Devices, December 4-6, 1995

Capattery – SuperCapacitor – Designed for longer duration power hold-up and memory back-up applications.  Full operating temperature range of -55C to 85C

High energy density, up to 3 joules per cc, High reliability, 25 yrs., >1,000,000 cycles

Hybrid capacitors provide very high power and energy from devices much smaller and lighter than electrically equivalent tantalum wet, tantalum chip, or aluminum electrolytic capacitors.

Typical applications replace standard military capacitors, or augment batteries and power supplies where size, weight, reliability and quality are important factors of component selection.
