Super Low ESR Polymer Solid Aluminum Electrolytic Capacitors for High Frequency Applications

Overview

Polymer solid aluminum electrolytic capacitors are designed for circuits requiring low equivalent series resistance (ESR) and stable performance at high frequency.
The TS13EY series developed by Suntan targets power designs where ripple handling, impedance control, and frequency response are critical selection factors.

Key Electrical Characteristics

• Super low ESR suitable for high ripple current environments
• Stable impedance across high frequency ranges
• Solid polymer electrolyte structure
• Improved thermal stability compared with liquid electrolyte types
• Suitable for high density PCB layouts

High Frequency Performance

In switching power supplies and DC-DC converters, capacitor impedance at high frequency directly affects output voltage ripple and transient response.
Polymer aluminum capacitors provide lower ESR than conventional aluminum electrolytic capacitors, enabling reduced power loss and improved filtering efficiency.

Applications

• Switching power supplies
• DC-DC converters
• Motherboards and CPU power regulation modules
• Industrial power control circuits
• High frequency filtering and decoupling

Design Considerations

• Select capacitance and voltage rating based on ripple current requirements
• Evaluate ESR impact on output ripple and thermal performance
• Consider layout proximity to switching devices for optimal decoupling
• Verify operating frequency range in relation to impedance characteristics
