LKG2A682MKZ

The LKG2A682MKZ is a lug-terminal aluminum electrolytic capacitor from Nichicon's LKG series, specified at 6800 µF (6.8 mF) and 100 V. It is purpose-designed for audio equipment, with the LKG series' emphasis on high-grade audio performance.

This part offers high capacitance and a robust ripple-current rating in a radial can with solder-lug (lag terminal) mounting. Note: this specific part is designated End Of Life.

Key Features

• Capacitance & Voltage — 6.8 mF (6800 µF) rated at 100 V for high energy storage in power filtering and smoothing applications.
• Tolerance & Loss — Capacitance tolerance of ±20% and a tangent of loss angle (tanδ) of 0.25 measured at 20°C, 120 Hz for predictable AC performance.
• Ripple Current — Low-frequency ripple current rating of 6.2 A at 120 Hz, supporting demanding low-frequency load conditions.
• Leakage Current — Specified leakage current of 2470 µA (measured per datasheet conditions), enabling designers to budget standby and bias currents accurately.
• Temperature & Endurance — Operating range −40°C to +85°C with an endurance rating of 1000 hours at 85°C under rated voltage.
• Mechanical & Mounting — Radial can with solder lug (lag terminal) package; size φ50 × 80L (approx. L: 8 × D: 5 cm) and supplied in tray packing for handling.
• Compliance — RoHS compliant as documented in the product data.

Typical Applications

• Professional audio power supplies — Bulk energy storage and smoothing for amplifier rails where high capacitance and 100 V rating are required.
• High-fidelity preamplifiers and amplifiers — Supply decoupling and low-frequency ripple handling to support stable audio performance.
• Power filtering in audio peripherals — Use in mixers, processors, and studio equipment for regulated DC smoothing and transient buffering.

Unique Advantages

• High bulk capacitance at elevated voltage — 6.8 mF at 100 V provides substantial energy reserve for demanding audio power rails.
• Measurable low-frequency performance — 6.2 A ripple-current rating at 120 Hz gives clear guidance for thermal and ripple budgeting in audio power designs.
• Audio-focused series design — Part of Nichicon's LKG family, which is specified for audio use and developed with priority on fidelity in audio equipment.
• Durability under thermal stress — Rated for 1000 hours at 85°C, enabling predictable end-of-life behavior for lifecycle planning.
• RoHS compliance — Meets environmental directive requirements included in the product data for regulated markets.
