• Loss Tangent (tanδ) — tanδ = 0.08 at 20 °C, 120 Hz, supporting stable dissipation characteristics for audio and power circuits.
• Ripple Current Capability — Rated low‑frequency ripple current of 1.05 A at 120 Hz and high‑frequency ripple current of 1.575 A at 10 kHz (values at 85 °C / specified frequencies).
• Endurance & Temperature Range — 2000 hours at 85 °C endurance rating; operating temperature range −40 °C to 85 °C.
• Radial Can Package — φ16 × 30.5 mm can with 7.5 mm lead spacing (±0.5 mm) for through‑hole assembly and mechanical stability.
• Packaging Options — Available in bulk (no terminal forming) and bag packing to suit assembly and handling preferences.
• RoHS Compliant — Meets RoHS requirements as noted in product documentation.

Typical Applications

• Audio systems — Specified for audio applications, suitable where 680 µF at 63 V and low leakage are required for power supply decoupling and energy storage.
• Through‑hole power filtering — Radial lead, can‑style construction and 7.5 mm lead spacing make it appropriate for through‑hole PCB filtering and bulk capacitance on power rails.
• Amplifier power rails — Combination of low tanδ, defined ripple current ratings at 120 Hz and 10 kHz, and 63 V rating supports smoothing and decoupling in amplifier power stages.

Unique Advantages

• Low leakage series design — Part of Nichicon’s UKL low leakage family, delivering minimized leakage current (85.68 µA) that helps preserve performance in bias‑sensitive circuits.
• Measured ripple performance at multiple frequencies — Specified ripple current at both low (1.05 A at 120 Hz) and high frequency (1.575 A at 10 kHz) supports designers addressing a range of switching and audio‑band conditions.
• Stable dissipation characteristics — tanδ of 0.08 at 20 °C and 120 Hz indicates controlled loss behavior for predictable thermal and audio performance.
• Robust endurance rating — 2000 hours at 85 °C provides a quantified lifecycle metric for thermal stress planning and reliability assessment.
• Compact radial can form factor — φ16 × 30.5 mm dimensions with 7.5 mm lead spacing enable compact through‑hole layouts while providing substantial capacitance.
• RoHS compliance — Conforms to RoHS directive as documented for regulatory and environmental needs.
