LKG1J682MKN

The LKG1J682MKN is an aluminum electrolytic capacitor from Nichicon's LKG series designed for high-grade audio equipment. It delivers 6800 µF capacitance at a 63 V rating in a snap-in / radial can package intended for robust power filtering and energy buffering in HD audio applications.

Engineered with audio performance and reliability in mind, this polarized capacitor combines large capacitance, a 4.3 A ripple-current capability at 120 Hz, and RoHS compliance to meet the needs of professional and consumer high-fidelity systems.

Key Features

• Capacitance & Voltage: 6800 µF nominal capacitance with a 63 V rated voltage and ±20% tolerance, providing substantial energy storage for audio power rails.
• Audio-focused design: Part of the LKG series specified for high-grade audio equipment and HD audio tone quality, aimed at preserving fidelity in power supply and signal environments.
• Ripple handling: Rated ripple current of 4.3 A at 120 Hz, suitable for smoothing low-frequency rectifier ripple in audio power supplies.
• Package & Mounting: Radial can with solder lug (snap-in terminal style) for secure board mounting and reliable mechanical retention.
• Operating range: Specified operating temperature from −40 °C to +85 °C to cover typical audio system environments.
• Endurance: Rated life of 1000 hours at 85 °C; after that test the capacitance remains within ±20%, tan δ remains within 200% of initial, and leakage current remains at or below the initial specified value.
• Leakage current specification: After 5 minutes at rated voltage and 20 °C, leakage current is ≤ 3√(C·V) μA (C in μF, V in volts), enabling predictable quiescent behavior.
• Low-temperature stability: Impedance ratios for low-temperature performance are specified: Z(−25 °C)/Z(+20 °C) ≤ 4 and Z(−40 °C)/Z(+20 °C) ≤ 12.
• Identification & compliance: Marked with gold lettering on a black sleeve and compliant with RoHS (2011/65/EU, (EU)2015/863).
• Polarized design: Polarized electrolytic construction for DC power applications common in audio systems.
• Physical size: Body dimensions approximately 6.8 cm × 3.5 cm (L × D) for layout and enclosure planning.

Typical Applications

• Power supply smoothing for audio amplifiers: Bulk energy storage and low-frequency ripple smoothing on amplifier rails to support consistent audio performance.
• High-fidelity audio equipment: Use in professional and consumer HD audio systems where tone quality and stable power delivery are priorities.
• Studio and pro-audio electronics: Filtering and decoupling in mixers, preamps, and other studio gear that require dependable electrolytic bulk capacitance.
• Audio system power modules: Energy buffering in power supply modules and discrete regulator circuits within audio components.

Unique Advantages

• High bulk capacitance: 6800 µF provides substantial charge storage for improved low-frequency energy support in audio power rails.
• High voltage margin: 63 V rating enables use on higher-voltage audio supply rails compared with lower-voltage electrolytics.
• Designed for audio fidelity: Series-level design emphasis on tone quality aligns component selection with HD audio requirements.
• Robust ripple performance: 4.3 A ripple current at 120 Hz reduces heating and stress under rectified load conditions common in audio power supplies.
• Specified endurance and stability: 1000 hours at 85 °C endurance and defined low-temperature impedance ratios provide predictable long-term behavior.
• Regulatory compliance and clear marking: RoHS compliance and gold-on-black sleeve marking simplify specification and identification in production.
