LKG1H821MESACK

The LKG1H821MESACK from Nichicon is an aluminum electrolytic, snap‑in terminal capacitor engineered for audio equipment applications. It provides 820 µF of capacitance at a 50 V rating in a compact snap‑in can package designed for high‑fidelity audio designs.

Key electrical characteristics include a low‑frequency ripple current rating of 1.35 A (120 Hz), a specified leakage current of 600 µA, and an endurance rating of 1000 hours at 85 °C. The part is RoHS compliant and intended where reliable power filtering and energy storage are required in audio systems.

Key Features

• Capacitance & Voltage — 820 µF rated capacitance at 50 V for bulk energy storage and supply stabilization in audio circuits.
• Low‑Frequency Ripple Handling — Rated ripple current of 1.35 A at 120 Hz, suitable for smoothing low‑frequency power variation in audio power supplies.
• Leakage Current — Specified leakage current of 600 µA after voltage application, enabling predictable quiescent behavior in bias and power rails.
• Endurance — Life rating of 1000 hours at 85 °C with performance limits defined for capacitance change, tan δ, and leakage current after recovery to 20 °C.
• Temperature Range & Stability — Operating range from −40 °C to 85 °C; impedance and stability characteristics specified across low temperatures for reliable operation in varied environments.
• Package & Mounting — Snap‑in (radial, can – snap‑in) mounting for secure board attachment in power assemblies and chassis installations.
• Physical Size & Tolerance — Compact form factor (φ25 × 25 L; L: 2.5 cm × D: 2.5 cm) with capacitance tolerance of −20% to +20%.
• Regulatory — RoHS compliant.

Typical Applications

• Audio power supplies — Bulk filtering and smoothing where 820 µF at 50 V and 1.35 A ripple handling improve supply stability for amplifiers and preamps.
