Key Features

• Capacitance & Voltage — 6.8 mF capacitance with a 6.3 V rated voltage and ±20% tolerance, providing bulk energy storage for DC filtering and decoupling.
• Low Impedance — Specified impedance of 56 mΩ to minimize voltage ripple and improve transient response in power rails.
• Ripple Current Performance — Rated ripple current of 2.116 A at 120 Hz and 2.49 A at 10 kHz, enabling reliable operation under switching loads and higher-frequency ripple conditions.
• Automotive-Grade Reliability — AEC-Q200 rating and an endurance specification of 8,000 hours at 105°C, supporting long-term performance in harsh environments.
• Wide Operating Temperature Range — Rated for –55°C to 105°C to cover a broad range of environmental conditions.
• Through-Hole Radial Lead Package — Radial lead, can package with 7.5 mm lead spacing and compact dimensions (L: 2 × D: 1.8 cm) for straightforward PCB mounting and mechanical robustness.
• Polarized Electrolytic Design — Polar capacitor construction appropriate for DC power-supply filtering applications.

Typical Applications

• Switching Power Supplies — Bulk filtering and output smoothing for switching regulators where low impedance and high ripple capability reduce output ripple and improve regulation.
• Automotive Power Electronics — Energy storage and decoupling in automotive systems, taking advantage of AEC-Q200 qualification and extended high-temperature life.
• DC-DC Converters — Input/output filtering and transient energy support in compact, high-density DC-DC converter modules.

Unique Advantages

• Low ESR for Cleaner Power — 56 mΩ impedance reduces losses and voltage ripple, improving converter efficiency and transient performance.
• High Ripple Handling — Measured ripple currents at both low and high frequencies (2.116 A at 120 Hz; 2.49 A at 10 kHz) enable reliable operation across switching regimes.
• Automotive-Grade Assurance — AEC-Q200 rating combined with 8,000 hours endurance at 105°C supports deployment in automotive and other demanding applications.
• Compact Footprint — Small radial-can dimensions (L: 2 × D: 1.8 cm) allow designers to free board space without sacrificing capacitance.
• Broad Temperature Range — –55°C to 105°C rating covers extreme ambient and thermal operating conditions common in industrial and automotive systems.
• Radial Lead Form Factor — Through-hole mounting simplifies assembly for mixed-technology PCBs and provides mechanical strength for rugged applications.
