Evans Capacitor manufactures high energy density capacitors for demanding defense and aerospace applications. Typical applications replace standard military capacitors, or augment batteries and power supplies where size, weight, reliability and quality are important factors of component selection.
Hybrid capacitors have extremely high power density, unbeatable for pulse radar
and laser applications. With high energy density, Hybrid capacitors are also well suited for bridge power or bus power interruption buffers.
The effective series resistance (ESR) of single cell Hybrid Capacitors is much lower compared to other supercapacitors of similar voltage rating. This leads to a very low time constant of 1ms, or less, making Hybrid capacitors well suited for high-rate applications.

THQ, THS3 and TDD SERIES
 
THQ SERIES
 
 
THS3 SERIES
 

THQ Hybrid Capacitors are perfectly suited for Defense and Aerospace applications requiring high power in a compact, hermetic, tantalum package. Applications include power interruption  buffer, filtering and high current pulse generation. Voltage range of 10V to 125V with full  operational temperature range of ‐55C to 125C. Capacitance values  increase from the THQ1 series up to the THQ5 series. THQ Hybrid Capacitors have very high curent capability, unlimited cycle life and environmental ruggedness with MTBF  >  5,000,000  hrs.
 
THS3 Hybrid Capacitor with square footprint, provides a 30% increase in capacitance over the standard THQ3 device in the same 0.6" height. THS3 is perfect for large energy storage needs, where space is at a premium. Proven unlimited cycle life and reliability of MTBF  >  5,000,000  hrs. New applications should favor the TDD3 style.

TDD SERIES
 
LOWEST ESR | HIGHEST ENERGY DENSITY
REDUCING SIGNIFICANTLY THE ESR
WITHOUT SACRIFICING CAPACITANCE AND VOLUME

TDD series Hybrid Capacitor have the highest power density and highest current capababilty of any Tantalum wet capacitor. Only 0.31" tall for the TDD1 to 0.60" high for the TDD3, makes TDD Hybrid Capacitors perfect for applications requiring high power where space and weight are at a premium. Ultra low ESR and compact construction allows very high current capability and extreme duty cycles.

Custom Packaging
1PTHQ3 Series - "Single Pack"
 
A Packaged THQ3 Hybrid Capacitor is available for harsh environmental conditions. The THQ3 capacitor is rigidly contained in an anodized aluminum package, fully potted with epoxy.  The case contains threaded insert mounting holes on the base. This packaged unit is suitable for higher
vibration environments, where the capacitor must be clamped in place with considerable force.

3STHQ3, 3PTHQ3 and 6PTHQ3 Series
 
Capacitor bank with 3 THQ3 series (or 6 THQ3 series) capacitors in series or parallel configuration. Completely wired and sealed in anodized aluminum case, fully potted with epoxy. The capacitor bank assemblies consist of internal THQ capacitors, soldered to a custom designed circuit board, with all necessary balancing resistors, and wiring. The assemblies are then completely sealed and epoxy potted in the rugged anodized aluminum case.
