Key Features

• Capacitance & Voltage: 10,000 µF nominal capacitance rated for 50 V, with tolerance of -20% to +20% (measured at 120 Hz, 20°C).
• Audio-grade design: Part of the LKG series specifically developed for high-grade audio equipment and HD audio use, prioritizing tone quality.
• Mounting & package: Snap-in terminal style in a radial can (snap-in) package for robust panel or chassis mounting; supplied in tray packing.
• Ripple handling: Low-frequency ripple current rated at 4 A (120 Hz), suitable for power smoothing in audio power supplies.
• Loss and leakage: Tangent of loss angle (tanδ) of 0.3 measured at 20°C, 120 Hz (50 V measurement condition); leakage current specified at 2120 µA.
• Temperature & endurance: Operating range from -40°C to +85°C with a rated endurance of 1000 hours at 85°C.
• Compact footprint: Case dimensions φ30 × 45 mm (L: 4.5 cm × D: 3.0 cm), polarised design for correct orientation in circuit.
• Compliance: RoHS compliant.

Typical Applications

• High-grade audio equipment: Bulk energy storage and smoothing in amplifier power supplies where tone quality and stability matter.
• HD audio systems: Decoupling and power filtering to support high-fidelity playback systems and studio electronics.
• Audio power stages: Supply rail stabilization for discrete and class‑AB/Class‑D amplifier modules requiring high capacitance and ripple handling.

Unique Advantages

• Audio-focused specification: Part of the LKG family developed for high tone quality, aligning component selection with audio system goals.
