Miniature Micro-Layer Capacitors

Yes, Exxelia offers custom configurations and extended/intermediate values upon request. This flexibility allows for tailored solutions to meet specific application requirements and could help your design with easiest integration, cost saving, thermal management optimization, sensors or filter integrations etc...

The MML capacitors feature:

• Non-Inductive Stacked Metallized Polymer Film: Ensures high performance and reliability.
• Encapsulation: Encapsulated in a flame-retardant high-temperature epoxy resin or molded diallyl phthalate (DAP) housing for mechanical and environmental protection.

The MML Series includes several types:

• D Series (bus bars integrated for power electronic conversion or filtering)
• M Series (Small package with radial, DIL or SMD connections)
• C Series (Flat package with DIL connections)
• Custom solution with specific casing and connections to optimize the integration, the heat management and some electrical characteristics.

Each type offers various configurations to suit different applications.

MML Series capacitors are suitable for aerospace & defense: withstand harsh environments and high reliability requirements.

• Inverter
• DC-Link
• Rectifier
• Energy storage

Exxelia's MML Series capacitors boast several key features:

• High Energy Density and High Temperature Capability: Operates effectively up to 140°C.
• Size and Weight Reduction: Up to 50% reduction compared to traditional film technologies and up to 10 times lighers comparing to the ceramic capacitors.
• Stable Performance: Maintains consistent performance across a wide temperature and voltage range.
• Open circuit defect mode with self healing advantage
• Rugged and Lightweight Construction: Ideal for demanding applications.
• Self-Healing Properties: Ensures long-term reliability and safety.

General Electrical Specifications:
