LKG1K821MESBBK

The LKG1K821MESBBK from Nichicon is an audio-grade snap-in aluminum electrolytic capacitor in the LKG series, specified for high-fidelity audio equipment. This TYPE-II (BK / Gold Tune) snap-in can delivers 820 µF at 80 V in a compact φ30 × 20 mm can and is supplied in tray packaging.

Designed for audio applications, the component offers specified low-frequency ripple handling, defined loss characteristics, and a 1000-hour endurance rating at 85°C. Note: this part is listed as End Of Life—please request current availability.

Key Features

• Capacitance & Tolerance — 820 µF nominal capacitance with a tolerance of ±20% at 20°C, 120 Hz.
• Rated Voltage — 80 V DC rating for higher-voltage audio power rails and supply sections.
• Audio Grade — TYPE-II (BK) — LKG series TYPE-II (BK / Gold Tune) construction intended for high-fidelity audio equipment.
• Low Loss Angle — tan δ = 0.25 (measured at 20°C, 120 Hz), supporting controlled dissipation in audio circuits.
• Ripple Current Handling — Low-frequency ripple current rated at 2.05 A (120 Hz) for smoothing and power supply filtering.
• Leakage Current — Specified leakage current of 760 µA after application of rated voltage (measurement per product data).
• Endurance & Temperature Range — 1000 hours at 85°C endurance; operating temperature range −40°C to +85°C with defined stability at low temperatures.
• Mounting & Package — Snap-in radial can (φ30 mm diameter × 20 mm length) supplied in tray packing for production handling.
• Compliance & Identification — RoHS compliant; part marking is printed in gold on a black sleeve for easy identification.

Typical Applications

• Professional Audio Amplifiers — Bulk smoothing and power supply decoupling on high-fidelity amplifier rails where audio-grade components are required.
• High-Fidelity Power Supplies — Filtering and energy storage in audio equipment power supplies to support stable output under dynamic loads.
• Preamp and Signal Chain Support — Use in power sections of preamplifiers and other audio subsystems where low loss and defined leakage matter.

Unique Advantages
