EVANS Capacitor Company
Provides Apache With Capacitor Banks
 The Evans Capacitor
Company has won multiple contracts from Lockheed Martin Missiles and
Fire Controls in Orlando, FL, to supply capacitor banks for
production of the Apache helicopter Arrowhead Program. Arrowhead is the
MTADS/PNVS (Modernized Target Acquisition and Designation Sight / Pilot
Night Vision System) for AH-64 Apache attack helicopters.
Evans supplies two specially built and
packaged capacitor banks for the system. It has provided capacitor
banks for approximately 750 Arrowhead ship sets since 2006.
A 15-year-old firm in East Providence, RI,
the Evans Capacitor Company holds US Department of Energy and US
Military quality and performance ratings for the design and manufacture
of capacitors, which are frequently specified for mission critical
applications. David Evans, its president, holds 15 patents.
In April, 2006, The Evans Capacitor Company
was the recipient of the Lockheed Martin “Supplier Excellence Award”
for the Arrowhead Program, and has since been awarded a "Small Business
of the Year Award" and the presigious "Platinum Preferred Supplier"
award

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).
Details about Evans Hybrid Capacitors and
capacitor banks can be found here. For more

Capacitor Company, 401-435-3555 or chasd@evanscap.com.
