Exxelia unveils SMD high-voltage mica capacitors targeting space and defense applications

PARIS - Exxelia in Paris has introduced a new generation of surface-mount high-voltage mica capacitors designed for compact military, aerospace, medical, and industrial electronic systems that require high pulse performance and reliability in harsh operating environments.

The new CM-HVLP series, short for High-Voltage Low-Profile Reconstituted Mica Capacitors, combines pulse-handling and filtering capabilities in a compact surface-mount package intended for space-constrained electronic architectures. The capacitors are designed for applications requiring high-voltage operation, rapid charge and discharge cycles, and stability under repetitive electrical stress.

The company says the new capacitors are intended for use in pulse power circuits, high-voltage filtering applications, aerospace electronics, defense systems, medical equipment, and aviation platforms where reliability and miniaturization are critical design requirements.

The CM-HVLP series uses reconstituted mica dielectric technology, which Exxelia says provides stable capacitance values without voltage-related drift. The devices are also engineered for high energy density, low equivalent series inductance, and low equivalent series resistance to support ultra-fast discharge performance and high dV/dt operation during repetitive pulse cycles.

The components are designed in a compact 8080 package measuring 20 by 20 millimeters to support dense PCB layouts and ongoing miniaturization trends in high-power electronic systems.

Exxelia says the capacitors are qualified to stringent military standards and undergo testing for severe mechanical shock and vibration, thermal cycling from minus 55 degrees Celsius to 125 degrees Celsius, and long-duration endurance operation.

High-voltage capacitors are widely used in military and aerospace electronics for pulsed power systems, radar transmitters, directed-energy technologies, power conditioning, avionics, electronic warfare systems, medical imaging equipment, and spacecraft electronics. Low-profile, high-energy-density passive components are increasingly important as system designers seek to reduce size, weight, and power requirements while maintaining high reliability in harsh environments.

Technical specifications for the CM-HVLP series include capacitance values from 10 nanofarads to 750 nanofarads and voltage ratings from 2,500 VDISCH to 5,000 VDISCH and 1,500 VDC to 4,000 VDC.
