QUANTIC EVANS is an AS9100/ISO 9001 certified manufacturer that designs and builds the industry’s most power dense capacitors. These capacitors operate in the low to medium voltage range (10V-125V), are used in countless avionics applications and are qualified and in service with all tier 1 aerospace and defense contractors.

When compared to traditional capacitor technologies, they offer significant savings of space, weight, and power. They are 1/10 the size of traditional tantalum capacitors and 1/4 the size the industry’s most advanced aluminum electrolytic capacitors. 

They are used on the E-2D Advanced Hawkeye surveillance and battlespace command aircraft, F35 Join Strike fighter, F15 Eagle, F18 Hornet and Boeing 787 Jet Airliner to name a few. There are dozens of additional aerospace, UAV, and miscellaneous avionics applications which use capacitors manufactured by QUANTIC EVANS but cannot be specifically named due to security and confidentiality reasons.
