Aerospace/Aviation

Aerospace/Aviation

Sensitive equipment used in aircraft is at risk of damage from power surges and spikes caused by lightning, switching transients, and other sources of electrical noise. EMI filters play a crucial role in eliminating the constant threat that electromagnetic interference (EMI) poses to electronic devices in the aerospace and aviation industries. These applications demand sturdy, light weight, and reliable filters able to withstand extreme temperatures, vibrations, and altitudes.

Captor Corporation delivers reliable, custom aviation and aerospace filters that meet the demanding standards of airborne communication systems, radar systems, navigation electronics, flight control units, and in-flight entertainment systems. Our custom EMI filters are built to withstand extreme conditions, from high G-forces to wide temperature fluctuations.

Some of the most common applications of our EMI aviation filters include:

  • Aircraft engine control units
  • Avionics and heads-up-display systems
  • RF communication modules
  • Flight safety systems
  • Navigation and telemetry equipment
  • Propeller de-ice timers

Our in-house machine shop gives us the flexibility to offer quick turnaround times for prototypes and volume production, delivering custom filters that meet your aircraft industry needs.
