Designed within Nichicon's LKG series for audio applications, this part offers a combination of high voltage capability, measurable ripple handling and defined thermal endurance suited to high‑fidelity audio power and filtering circuits.

Key Features

• Capacitance & Voltage — 680 µF nominal capacitance with a 100 V rated voltage and a capacitance tolerance of ±20% (120 Hz, 20°C).
• Audio‑Focused Design — Part of the LKG series developed for audio equipment; the series documentation emphasizes tone quality and use in high‑grade audio designs.
• Mounting & Package — Snap‑in terminal, radial can (φ22 × 35 mm), suitable for secure mechanical retention in chassis or PCB assemblies.
• Temperature Range — Operating temperature range from −40°C to +85°C for a wide set of ambient conditions.
• Endurance — Rated lifetime of 1000 hours at 85°C with specified endurance limits for capacitance, tan δ and leakage current after test.
• Ripple & Leakage — Low‑frequency ripple current capability of 2.15 A at 120 Hz and a specified leakage current value (product data) of 780 µA.
• Compliance — RoHS compliant as documented for the LKG series.

Typical Applications

• High‑grade Audio Amplifiers — Bulk filtering and power smoothing where 680 µF at 100 V is required to maintain stable supply rails.
• Professional Audio Equipment — Use in mixers, preamps and studio gear that benefit from audio‑focused capacitor characteristics.
• Power Supply Filtering for Audio Systems — Energy storage and ripple suppression in audio power supplies and regulated stages.
• Crossover and Signal Conditioning — Where polarized electrolytic capacitance is needed in audio frequency networks and filtering circuits.

Unique Advantages

• Audio‑oriented engineering: Supplied from the LKG series, which is documented as designed for high‑grade audio equipment and prioritizes tone quality.
• High voltage headroom: 100 V rating enables use in higher‑voltage audio power stages and power supply rails.
• Robust ripple handling: 2.15 A ripple current (120 Hz) supports demanding low‑frequency filtering duties in power supplies.
• Defined endurance: 1000 hours at 85°C with post‑test limits for capacitance, tan δ and leakage current gives a clear reliability target for design validation.
• Secure snap‑in mounting: Radial snap‑in can provides mechanical retention for chassis or board installations where vibration or handling may occur.
• Regulatory compliance: RoHS compliance supports use in environments requiring banned‑substance restrictions.
