LKG1H682MKNS

The LKG1H682MKNS is a lug-terminal, polarized aluminum electrolytic capacitor in Nichicon’s LKG series, specified at 6800 µF and 50 V. It is designed for audio equipment applications where large bulk capacitance and reliable low-frequency ripple handling are required.

Key electrical characteristics include a low-frequency ripple current rating of 5.5 A (120 Hz), a dissipation factor (tanδ) of 0.22 at 20°C/120 Hz, and an endurance rating of 1000 hours at 85°C. The part is RoHS compliant and supplied in tray packing; current status is End Of Life.

Key Features

• High Capacitance & Voltage: 6800 µF rated capacitance at 50 V provides substantial energy storage for power smoothing and reservoir applications.
• Terminal & Package: Lug (solder lug) terminal mounting in a radial can package enables secure mechanical connection and robust current flow for high-current audio power stages.
• Low-Frequency Ripple Handling: Rated low-frequency ripple current of 5.5 A (120 Hz) supports heavy ripple environments typical in audio amplifier power supplies.
• Dissipation Factor & Leakage: tanδ of 0.22 (measured at 20°C, 120 Hz) and specified leakage current (1,740 µA) provide quantifiable loss and leakage behavior for system-level power budgeting.
• Endurance & Temperature Range: Life/Endurance rated 1000 hours at 85°C with operating temperature from −40°C to +85°C, allowing specification for elevated-temperature environments and expected end-of-life change limits per datasheet.
• Form Factor & Packaging: Size φ40 × 80 mm length with tray packing for handling and placement; polarized design targeted for audio circuitry.
• Regulatory: RoHS compliant as specified for environmental directive adherence.

Typical Applications

• High-grade audio amplifiers: Bulk reservoir and power-supply smoothing to support steady DC rails for amplifier stages and reduce low-frequency ripple in power rails.
• Audio power supplies: Filtering and energy storage in linear and discrete-regulator designs where large capacitance and ripple handling are required.
• High-fidelity audio equipment: Where the LKG series’ audio-focused design attributes are incorporated to prioritize sound quality and stable supply performance.

Unique Advantages

• Substantial energy storage: 6.8 mF capacitance provides significant charge reservoir capacity for transient and steady-state demands.
• Designed for audio use: Series-level design intent emphasizes performance characteristics valued in high-fidelity audio applications.
• Quantified ripple capability: 5.5 A low-frequency ripple rating gives clear guidance for thermal and ripple budgeting in power-stage designs.
• Measurable loss characteristics: Specified tanδ and leakage current allow designers to assess dissipation and standby losses accurately.
• Wide operating range: −40°C to +85°C operation and 1000-hour endurance at 85°C provide a defined reliability envelope for system qualification.
• RoHS compliant packaging: Tray packing and RoHS compliance facilitate implementation in lead-free production environments.
