Evans Capacitor Company is an AS9100/ISO 9001 certified manufacturer that designs and builds EVANSCAPS, the industry’s most power dense capacitor. EVANSCAPS 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, EVANSCAPS 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. 

EVANSCAPS 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 EVANSCAPS but cannot be specifically named due to security and confidentiality reasons. 

Evans Capacitor Company’s trusted and proven capacitors have been used for over 20 years in a variety of applications that require rugged, innovative, high-reliability solutions and they continue to deliver, making them the preferred choice for today’s cutting-edge products.
