Precision Energy for Mission-Critical Initiation

The Knowles Advantage

Knowles provides high-voltage ceramic capacitors engineered for pulse discharge applications that meet MIL-PRF standards and are optimized for energy density, low ESR, and rapid rise times. Our capacitors enable capacitor discharge units (CDUs) and firesets to deliver precise, repeatable pulses for safe-and-arm devices in missiles, munitions, and aerospace systems. With proven reliability up to 250°C and advanced dielectric formulations, Knowles ensures mission success when timing and safety are paramount.

Knowles’ components can be found in the following applications:

  • Exploding Foil Initiators (EFI): High voltage initiation systems with precise, EMI-resistant actuation. 
  • Exploding Bridgewire Detonators (EBW): Reliable, ultra-fast detonators for extreme thermal, shock, and vibration conditions.
  • Flight Termination & Range Safety Systems: Instant pyrotechnic systems for range safety. 
  • Insensitive Munitions & Safe and Arm Devices: IM-compliant initiation with advanced safety controls.

How Pulse Forming Networks Shape High Energy Pulses

How Pulse Forming Networks Shape High Energy Pulses

From high-power radar to advanced medical imaging, many cutting-edge technologies rely on precisely controlled high-energy pulses. However, generating a pulse that delivers consistent power without distortion isn’t as simple as discharging a capacitor. These systems rely on Pulse Forming Networks (PFNs) to shape and control high-energy pulses.
