In this context, RUBYCON, a long-time partner of the specialist distributor CODICO, presents its new MXZ series of electrolytic capacitors , a solution that allows increasing capacity and ripple current while maintaining exactly the same mechanical size.
An evolution in aluminum electrolytic capacitor technology:
The performance of an electrolytic capacitor depends directly on the effective surface area of the aluminum anode. Traditionally, this surface area is increased through chemical etching processes, generating microstructures that increase the available area. (Figure 1)
The MXZ series introduces a different approach: the use of powder-coated aluminum foil, an additive technology that further increases the material's active surface area.
The result is a tangible improvement in electrical performance, positioning the MXZ series as a significant advancement in next-generation electrolytic capacitors.
More performance without compromising design.
Compared to previous generations, such as the MXT series, the new MXZ offers clear and measurable improvements:
• Approximately 10% increase in capacity for the same size
• 15% to 25% increase in ripple current
• Higher power density in compact applications
These features allow the designer to choose between increasing system performance without redesigning the PCB or reducing the number of components while maintaining the same performance.
Designed for demanding applications,
the MXZ series has been specifically developed for environments where reliability and robustness are critical, such as:
• Industrial power supplies
• Electric vehicle charging systems
• Renewable energy inverters
• Automation and motor control electronics
With a nominal voltage of 450 VDC, these capacitors are especially suitable for DC-link and energy storage applications in modern power systems.
Guaranteed reliability under demanding conditions.
In addition to electrical performance, RUBYCON maintains its focus on long-term reliability. The MXZ series offers:
• 3,000-hour service life at 105°C
• Capacitance variation within ±20% after lifetime testing
• Leakage current controlled according to specifications.
This ensures stable performance even under demanding thermal and electrical conditions, reducing risks and maintenance costs in the long run.
Wide range of values and standard formats
The MXZ series covers a wide range of needs within power applications:
• Capacities from approximately 380 µF to 2510 µF at 450 V
Sizes from Ø22 × 45 mm to Ø35 × 100 mm
Ripple current up to 4.5 A (120 Hz, 105 °C)
The standard snap-in format allows direct integration into existing designs, facilitating both new implementations and upgrades of systems already in production.
Direct impact on system design
From an electronic design perspective, the MXZ series offers clear advantages:
• Higher capacity per volume → improved DC bus stability
• Higher current capacity → reduced thermal stress
• Improved overall system efficiency
• Reduction in the number of components required
In short, it is a solution that helps simplify the design and increase the reliability of the final system.
Conclusion
The RUBYCON MXZ series It demonstrates how innovation in materials and manufacturing processes can translate into concrete improvements at the system level.
With higher capacity, higher ripple current, and an identical form factor to previous generations, these capacitors represent an ideal choice for engineers looking to optimize their designs without compromising space or reliability.
