Key electrical and mechanical characteristics include a wide operating temperature range, RoHS compliance, and specifications tuned for stable performance under audio-system ripple conditions.

Key Features

• High Capacitance (6.8 mF): 6800 µF nominal capacitance for effective bulk energy storage and low-frequency smoothing in audio power rails.
• 63 V Rated Voltage: Provides headroom for higher-voltage audio power supply topologies and ensures reliable operation at the specified system voltage.
• Lug / Snap-in Terminal Configuration: Series design supports lug and snap-in terminal styles; package case noted as radial can with solder lug suitable for robust chassis or board mounting.
• Compact Can Dimensions: Physical size approximately φ40 × 100 mm (L: 10 × D: 4 cm / height seated max 3.937 inch), enabling high capacitance in a cylindrical radial package.
• Temperature and Endurance: Rated for operation from −40°C to +85°C with endurance specified as 1000 hours at 85°C (capacitance change within ±20% after test).
• Ripple Current (Low Frequency): 6.1 A at 120 Hz, supporting audio-frequency ripple handling on power rails.
• Leakage and Loss Specifications: Leakage current after 5 minutes at 20°C is specified as not more than 3√CV (μA). Loss angle (tan δ) and impedance characteristics are defined per datasheet, with stability specifications at low temperature (Z ratios at −25°C and −40°C).
• RoHS Compliant: Compliant with RoHS directive (2011/65/EU, (EU)2015/863), supporting regulatory requirements for electronics manufacturing.
• Audio-grade Design: Series is explicitly developed for high-tone-quality audio use, meeting the needs of HD audio equipment.

Typical Applications

• High-end Audio Amplifiers: Bulk filtering and power-supply smoothing to support stable rail voltages and low-noise playback.
• Professional Audio Systems: Power energy storage and ripple suppression in mixers, powered speakers, and studio equipment.
• Consumer HD Audio Equipment: Use in high-fidelity receivers and integrated amplifiers where sound quality is prioritized.

Unique Advantages

• Substantial Energy Storage: 6800 µF capacity delivers significant bulk charge for power-supply stability in audio designs.
