The Evans Capacitor Company Receives Prestigious Preferred Supplier Award from Lockheed Martin

Hybrid Capacitors save weight volume and cost when compared to military tantalum wet capacitors.The Evans Capacitor Company, designer and manufacturer of the Hybrid® supercapacitor, has received the Lockheed-Martin “Preferred Supplier” award.

The honor follows design and production of a series of complicated capacitor banks for the Apache helicopter Arrowhead Program. The Evans Capacitor banks are critical to the functioning of the Arrowhead MTADS/PNVS (Modernized Target Acquisition and Designation Sight / Pilot Night Vision System) for AH-64 Apache attack helicopters.

In April, 2006, Evans Capacitor received the “Supplier Excellence Award” for the Lockheed Martin Missiles and Fire Controls Arrowhead program.

Capacitor banks for the Arrowhead use Evans Hybrid® Capacitors, completely wired and packaged in rugged aluminum housings, as line replaceable modules. One bank is rated at 50V and 144,000 µF, utilizing six THQ3050243 capacitors in parallel. The other bank is rated at +/- 135V and 1,100 µF, using three THQ125332 capacitors in series.

THQ3 capacitors utilize Evans patented Hybrid® Capacitor technology, which provides very high power density compared with other tantalum capacitors. Hybrid Capacitors have a tantalum pentoxide dielectric, in conjunction with a Ruthenium oxide cathode, providing high single cell voltages (high power density for pulse applications) and high capacitance (high energy density for power back up applications).
