Evans Capacitor develops high-power density capacitors for challenging naval defence applications, with energy storage devices offering interrupted backup supply for marine subsystems.

Reliable capacitors for laser diode drivers and phased-array radars

Low equivalent series resistance (ESR) capacitors provide high-current pulses for laser drivers and phased-array radars.

EVANSCAPS feature unlimited lifecycles and low inductance, ensuring reliability to critical naval systems. They provide reliable power solutions for many mission-critical systems and can withstand temperatures of -55°C-125°C.

EVANSCAPS are energy-efficient, compact and lightweight, helping to achieve demanding design goals, while they are available in a range of styles to meet specific maritime requirements.

Evans Capacitor provides energy storage devices, which offer high-powered density features for naval applications.
The company supplies rugged capacitors, providing high-current pulses for demanding marine operations.
Evans offers long-endurance capacitors, which can withstand temperatures of -55°C-125°C.

Energy-dense capacitors for naval systems

Handheld / airborne laser systems and phased-array radars require pulsed, solid-state diodes or transmit/receive (T/R) module pulses, which require high currents and bulk capacitance.

Capacitors are available in several DLA (DSCC) certified voltage and capacitance ratings (10V-125V) to provide optimised performance characteristics for maritime operations.

Theses highly efficient products minimise voltage droops for laser drivers and are coated in tantalum. They are airtight, with no outgassing to maintain high-performance optics.

Instant-power capacitors for marine applications

EVANSCAPS offer five to ten times the volumetric energy density of aluminium electrolytic capacitors and provide instant power.

They have ultra-low ESR, especially in the TDD series, to control vigorous duty cycles with minimal cooling requirements.

TDD series discharge voltages, currents, pulse widths / frequencies are modifiable to ensure maximum efficiency in naval subsystems.

Rugged capacitors for gallium nitride (GaN) T/R modules

Gallium nitride (GaN) radio frequency (RF) T/R modules provide advantages in energy density. EVANSCAPS expand this by offering the highest density capacitors to drive pulses.

EVANSCAPS feature a rugged design and demonstrate more than five million hours mean time between failures (MTBF) in powerful phased-array systems.

Capacitors have a density of up to 2J per cubic centimetre in the desired voltage range.

Legacy systems benefit by replacing older technology with high-powered GaN T/R modules for a more efficient naval system.
