Challenge
Avionics engineers must select an energy storage solution that ensures airborne electric systems meet the requirements of MIL-STD-704/DO-160, providing reliable power to the critical avionics systems throughout all phases of flight, including brief power interruptions.
Solution
Quantic™ Evans hybrid capacitors are purposefully crafted to meet the stringent requirements of MIL-STD-704/ DO-160, delivering power-dense, ultra-low ESR and reliable performance across wide temperature fluctuations, and the ability to withstand high altitude and vibration challenges, fluctuations, shock, vibration, and altitude variations.
What is MIL-STD-704/DO-160 Power Hold-up?
MIL-STD-704/DO-160 is a United States military standard that defines the requirements for aircraft electric power characteristics and mandates that an airborne electric system maintain power output during brief interruptions in the input power source. These brief interruptions can occur due to power fluctuations or momentary power interruptions, such as when the aircraft is starting up or shutting down its engines or switching from a generator to a battery. Capacitors are used in power hold up applications, particularly in situations where a very short duration of backup power is required. Capacitors can store electrical energy and release it quickly when needed, making them ideal for providing temporary power during brief interruptions or voltage sags. This requirement is important for ensuring that critical systems on the aircraft, such as avionics and flight control systems, continue to receive power even during brief interruptions in the power supply. By maintaining power during these interruptions, the power hold up requirement helps to ensure the safety and reliability of the aircraft's electrical systems.MIL-STD-704/DO-160 is a United States military standard that defines the requirements for aircraft electric power characteristics and mandates that an airborne electric system maintain power output during brief interruptions in the input power source.
