Polymer Solid Aluminum Electrolytic Capacitors for Low ESR High Frequency Applications

Overview

Polymer solid aluminum electrolytic capacitors are designed for high frequency power circuits requiring low ESR and stable electrical performance.
Solid conductive polymer electrolyte enables improved ripple current capability and reduced impedance compared to conventional liquid electrolyte types.

Series Coverage

• TS13EY-CDHEA: Super low ESR polymer aluminum electrolytic capacitors
• TS13EZ-CDHEB: Low ESR polymer aluminum electrolytic capacitors
• TS13CP: SMD polymer aluminum solid electrolytic capacitors

Electrical Performance Characteristics

• Low ESR for high frequency switching regulators
• Improved ripple current capability
• Stable impedance over frequency range
• Solid electrolyte structure for enhanced reliability

Role in Power Conversion Circuits

Low ESR capacitors reduce output ripple voltage and improve transient response in DC/DC converters and voltage regulator modules.
High frequency impedance stability supports efficient filtering in compact power designs.

Applications

• Switching mode power supplies
• DC/DC converter output filtering
• Voltage regulator modules
• High density digital power systems

Design Considerations

• Select ESR level according to ripple current requirements
• Match capacitance to transient load response targets
• Consider thermal dissipation in high density layouts
• Verify mounting type for through-hole or SMD assembly
