Key Features

• Capacitance & Voltage — 680 µF nominal capacitance with ±20% tolerance and a 6.3 V rated voltage for low-voltage rail applications.
• Low ESR — 10 mΩ equivalent series resistance measured at 20 °C/100 kHz, enabling improved transient response and reduced power loss at high frequency.
• High Ripple Current Capability — Rated ripple current of 550 mA at 120 Hz and 5.5 A at 300 kHz, supporting both low- and high-frequency ripple handling in switching supplies and DC–DC converters.
• Conductive Polymer Solid Electrolyte — Solid electrolyte construction for stable electrical characteristics and performance over temperature and frequency.
• Temperature & Endurance — Operating range −55 °C to 105 °C with 2000 hours endurance at 105 °C under rated voltage conditions.
• Package & Mounting — Radial lead can, size φ10 × 12.5 mm, with 5 mm lead spacing (±0.5 mm) for through-hole PCBs and straightforward assembly.
• Leakage Current — Specified leakage current of 642 µA (measured after 2 minutes at 25 °C), enabling predictable bias behavior in design.
• Production & Packaging — Offered in bulk/bag packing and listed as in mass production.

Typical Applications

• General-purpose power filtering — Bulk and decoupling capacitance on low-voltage rails where low ESR and high ripple handling improve regulator stability and transient response.
• Switching power supplies and converters — Supports high-frequency ripple currents (up to 5.5 A at 300 kHz) typical in DC–DC conversion stages.
• Embedded and industrial electronics — Reliable capacitance and endurance at elevated temperatures (2000 h at 105 °C) for sustained operation in constrained thermal environments.

Unique Advantages

• Low-loss operation: 10 mΩ ESR at 100 kHz reduces dissipation and improves efficiency in high-frequency circuits.
• High ripple tolerance: 5.5 A rated ripple current at 300 kHz enables use in demanding switching and decoupling roles.
• Temperature-hardened endurance: Rated for 2000 hours at 105 °C, providing predictable long-term performance in elevated-temperature applications.
• Compact radial package: φ10 × 12.5 mm can with 5 mm lead spacing simplifies through-hole integration while conserving board area.
• Predictable leakage characteristics: Specified leakage current of 642 µA supports reliable bias planning in power designs.
