It provides large bulk capacitance and elevated voltage capability to support power supply smoothing, decoupling and energy storage in professional and consumer audio systems.

Built to the Nichicon LKG series specification, this part combines 10 000 µF capacitance at an 80 V rating with series-level characteristics such as defined loss tangent and endurance for reliable performance in audio-focused power circuits.

Key Features

• High Capacitance: 10 000 µF (10 mF) nominal capacitance for substantial bulk energy storage and low-frequency filtering.
• Rated Voltage: 80 V DC rating suitable for higher-voltage audio power rails and supply stacks.
• Capacitance Tolerance: −20% to +20% tolerance, specified at 120 Hz and 20 °C, for predictable system-level design.
• Low-Frequency Ripple Handling: 6.2 A ripple current (measured at 120 Hz), enabling the capacitor to manage significant AC loading on power rails.
• Electrical Loss (tan δ): tanδ = 0.25 measured at 20 °C, 120 Hz, providing a quantified dissipation characteristic for thermal and noise calculations.
• Leakage Current: 2 680 µA specified value, useful for system leakage budgeting and bias considerations.
• Endurance: Rated for 1 000 hours at 85 °C with performance criteria for capacitance, tanδ and leakage current defined by the LKG series endurance specification.
• Temperature Range: Operating from −40 °C to +85 °C to cover common environmental conditions in audio equipment.
• Package & Mounting: Radial can with solder lug (lag terminal) mounting; physical size φ50 × 80 mm and tray packing for production handling.
• RoHS Compliant: Conforms to RoHS requirements as specified for the LKG series.
• Series Marking: LKG series parts are marked with gold lettering on a black sleeve for clear identification.
• Product Status: End of Life — refer to procurement or support for availability and alternatives.

Typical Applications

• Professional and Consumer Audio Power Supplies: Bulk smoothing and energy storage for amplifier rails and preamplifier power sections.
• High-Fidelity Audio Systems: Power decoupling in systems where stable low-frequency response and large reserve capacitance are required.
• Audio Signal Conditioning: Supporting DC supply stability for low-noise analog and mixed-signal audio circuits.

Unique Advantages

• Substantial Bulk Storage: 10 000 µF capacitance reduces voltage sag under load and provides extended energy reserve for dynamic audio peaks.
• High Voltage Capability: 80 V rating accommodates higher-voltage audio topologies and reserve headroom for stacked supplies.
• Measured Ripple Performance: 6.2 A ripple current rating at 120 Hz enables reliable handling of AC stress on power rails in audio applications.
• Defined Loss Characteristic: Specified tanδ (0.25 at 20 °C, 120 Hz) aids thermal and damping calculations during design validation.
• Temperature and Endurance Data: −40 °C to +85 °C operating range with a 1 000‑hour endurance rating at 85 °C provides clear, test-based reliability expectations.
• Lug-Terminal Package: Solder-lug mounting ensures robust mechanical and electrical connections for power-dense audio assemblies.
