LKG1K821MESZBK

The LKG1K821MESZBK is a snap-in aluminum electrolytic capacitor from Nichicon's LKG series, specified at 820 µF and 80 V. It is engineered for audio equipment applications and is described in the LKG series documentation as designed for high-grade audio equipment with a priority on high-fidelity sound quality.

As a polarized, snap-in radial can capacitor, it pairs high capacitance and an 80 V rating with a 2.05 A low-frequency ripple current capability and a 1000-hour endurance at 85 °C, making it suitable for power-filtering and energy-storage roles in audio modules and related systems.

Key Features

• Capacitance & Voltage: 820 µF rated capacitance with an 80 V rated voltage, suitable for mid- to high-voltage audio power stages and filter circuits.
• Audio-grade LKG Series: Part of Nichicon's LKG series, which is described as designed for high-grade audio equipment and prioritizes high-fidelity sound quality; the part code suffix "BK" corresponds to the TYPE-II (Gold Tune) grade in the LKG family.
• Low-frequency Ripple Handling: Rated low-frequency ripple current of 2.05 A at 120 Hz, supporting smoothing and decoupling duties in audio power supplies.
• Loss Characteristics: tan δ (dissipation factor) of 0.25 measured at 20 °C, 120 Hz, providing a quantified view of dielectric losses for design assessment.
• Leakage Current: Specified leakage current of 760 µA, useful for steady-state leakage budgeting in power designs.
• Operating Temperature & Endurance: Rated for −40 °C to +85 °C with an endurance rating of 1000 hours at 85 °C under rated voltage.
• Package & Mounting: Snap-in radial can package (φ22 × 30 mm length), supplied in tray packing for assembly handling and board mounting via snap-in terminals.
• RoHS Compliant: Meets RoHS directive requirements as noted in the LKG series documentation.

Typical Applications

• Audio Power Supplies: Bulk smoothing and decoupling in amplifier and preamplifier power rails where 820 µF and 80 V are required.
• High-Fidelity Amplifiers: Energy storage and transient support for high-grade audio amplifier stages, aligned with the LKG series audio focus.
• Audio Filter Networks: Use in low-frequency filter sections and power filtering where quantified ripple current and dissipation factor are important.

Unique Advantages

• Designed for Audio Quality: Part of the LKG family described for high-grade audio equipment, offering targeted specification and series-level design intent for fidelity-sensitive applications.
