LKG1K682MKZS

The LKG1K682MKZS is a lug-terminal aluminum electrolytic capacitor engineered for audio equipment. It combines high bulk capacitance with an 80 V rating and a lug (solder-lug) radial can package to support high-fidelity audio power supply and energy-buffering needs.

Designed for durability in audio applications, the capacitor delivers low-frequency ripple handling, defined loss characteristics at audio-relevant test conditions, and a broad operating temperature range for stable performance across typical audio system environments.

Key Features

• High Capacitance — 6800 µF (6.8 mF) capacitance for bulk energy storage and smoothing in power supply and amplifier applications.
• Rated Voltage — 80 V rated voltage to support higher-voltage audio power rails and robust headroom for system designs.
• Loss and Measurement — Tangent of loss angle (tanδ) = 0.2 measured at 20°C, 120 Hz, providing a quantified dissipation characteristic under standard audio-test conditions.
• Ripple Handling — Low-frequency ripple current rating of 6.7 A at 120 Hz for handling power-supply ripple and dynamic load demands.
• Leakage Current — Specified leakage current of 2210 µA, stated after rated voltage application, enabling predictable DC offset behavior in amplifier and supply circuits.
• Endurance and Temperature — Rated for 1000 hours at 85°C with an operating temperature range of −40°C to 85°C for reliable medium-term operation in varied environments.
• Mechanical & Mounting — Lug (solder-lug) radial can package with dimensions φ50 × 80 mm (L: 8 × D: 5 cm), supplied in tray packing for PCB or chassis-mounted installations.
• Compliance — RoHS compliant.

Typical Applications

• Audio Power Supplies — Bulk filtering and energy storage for amplifier rails where large capacitance and an 80 V rating support stable supply voltage under dynamic audio loads.
• High-Fidelity Amplifiers — Decoupling and reservoir capacitance to preserve signal integrity and sustain current delivery during transient peaks.
• Professional Audio Equipment — Power smoothing and ripple suppression in mixers, preamps, and other studio gear where predictable electrical behavior over 1000 h at 85°C is required.

Unique Advantages

• Substantial Energy Storage: 6.8 mF capacitance provides significant smoothing and bulk reserve for power-hungry audio stages.
• High Voltage Capability: 80 V rating enables use on higher-voltage rails, increasing design flexibility for amplifier topologies.
• Measured Audio-Range Loss: tanδ specified at 20°C/120 Hz (0.2) gives designers a clear datum for loss-related performance in audio frequencies.
• Robust Ripple Performance: 6.7 A ripple current rating at 120 Hz supports continuous ripple handling in power-supply applications.
• Durability Under Load: 1000-hour endurance at 85°C ensures stable capacitance and leakage characteristics for long-term audio equipment operation.
• Hardware-Friendly Form Factor: Lug-terminal radial can and tray packing simplify chassis or PCB mounting and mechanical retention for heavier, high-capacitance components.
