LKG1J821MESYCK

The LKG1J821MESYCK is a snap‑in aluminum electrolytic capacitor from Nichicon’s LKG series, engineered for audio equipment. It pairs a low‑profile snap‑in can package with audio‑grade design intent to support power filtering and decoupling in high‑fidelity audio systems.

Key electrical attributes include a rated voltage of 63 V, 820 µF capacitance with ±20% tolerance, and specifications tuned for reliable low‑frequency ripple handling and long endurance at elevated temperature.

Key Features

• Audio‑Focused Series LKG series — snap‑in terminal type designed for audio equipment and high‑grade audio applications as specified in the product series documentation.
• Electrical Performance 820 µF rated capacitance at 63 V with a tolerance of −20% to +20% and specified tanδ (DF) of 0.22 measured at 20°C, 120 Hz.
• Ripple and Leakage Low‑frequency ripple current capability of 1.9 A (120 Hz) and a measured leakage current of 680 µA, suitable for power supply smoothing in audio circuits.
• Reliability and Endurance Life rating of 1000 hours at 85°C; endurance specs require capacitance change within ±20% and leakage not exceeding initial specified value after the endurance test.
• Mechanical & Mounting Snap‑in radial can package (φ20 × 35 mm length) for PCB snap‑in mounting, providing a compact footprint and secure installation.
• Operating Range & Compliance Operating temperature −40°C to +85°C and RoHS compliant.
• Visual Identification Marked with gold‑color printing on a black sleeve as specified for the LKG series.

Typical Applications

• High‑End Audio Amplifiers — Power supply filtering and decoupling where audio fidelity and controlled ripple handling are required.
• Studio and Consumer Audio Equipment — Bulk energy storage and smoothing in preamps, mixers, and hi‑fi components designed for low noise.
• Power Supply Modules for Audio Systems — Local reservoir capacitors on regulator outputs and rail decoupling in audio power stages.

Unique Advantages

• Audio‑grade design intent — Part of the LKG family, which is specified for audio equipment, aligning component selection with audio performance goals.
• Strong ripple handling — 1.9 A ripple current (120 Hz) supports robust smoothing in low‑frequency audio power rails.
• Low leakage for lower noise floors — Specified leakage current of 680 µA contributes to stable bias conditions in sensitive audio circuits.
• Compact snap‑in package — φ20 × 35 mm radial snap‑in can enables secure PCB mounting while minimizing board area.
• Rated endurance at elevated temperature — 1000 hours at 85°C provides a defined lifetime expectation for reliability planning.
• Regulatory compliance — RoHS compliance supports use in designs requiring restricted‑substance conformity.
