Next-Generation SMD High Voltage Mica Capacitors

The new CM-HVLP series (High-Voltage Low-Profile Reconstituted Mica Capacitors) addresses growing demand for high-voltage, robust, and low-profile components in volume-constrained electronic systems.

The new capacitors are engineered to meet the requirements of applications where high voltage handling, fast charge/discharge cycles, and reliability under repetitive stress are essential. Their design enables use in both pulse applications—such as charge and discharge circuits—and high-voltage filtering functions, offering a versatile solution for advanced electronic architectures.

The CM-HVLP series combines the intrinsic stability of reconstituted mica dielectric technology without any drift under voltage of the capacitance value and a breakthrough compact SMD footprint, supporting the ongoing miniaturization of high-power electronic systems. The capacitors provide high energy density, very low Equivalent Series Inductance (ESL), and the capability to withstand extreme dV/dt rates, enabling ultra-fast discharge performance even under intensive repetitive cycles. The design is also optimized to propose low ESR value.

Space Heritage & Extreme Reliability

Leveraging a long-standing experience with Space QPL reconstituted mica capacitors, Exxelia is now introducing this same technology through the new CM HVLP series, specifically designed to meet the stringent requirements of the defense market. To ensure mission-critical reliability, qualification tests are performed according to the most stringent MIL standards, including:

• Mechanical: Severe shock and vibration profiles.
•  Thermal: Extreme temperature cycling ranging from -55°C to +125°C.
• Long endurance life-test

Unmatched Miniaturization

Designed with integration in mind, the components feature a reduced footprint that facilitates placement in dense PCB layouts. The series offers a significant size advantage, with a format (8080) measuring only 20x20mm. This balance between miniaturization and power capability makes the technology particularly relevant for Space, Aerospace, Defense, Medical, and Aviation systems, where reliability and electrical stability are critical.

The new SMD high-voltage mica capacitors will be officially presented during the Components for Military & Space Electronics (CMSE) 2026, taking place April 28–30, 2026, in Los Angeles, USA. Visitors will be able to discover the technology on the Exxelia booth B13, where the company will showcase its latest developments in high-reliability passive components for demanding environments.
