LKG1K821MESYBK

The LKG1K821MESYBK from Nichicon is an aluminum electrolytic, snap‑in terminal capacitor in the LKG series designed for audio equipment. It provides 820 µF nominal capacitance at a rated voltage of 80 V in a compact radial can snap‑in package (φ20 × 35 mm / 2.0 × 3.5 cm).

Engineered for high‑grade audio uses, this TYPE‑II (BK) grade device emphasizes fidelity‑oriented performance with a polarized design, RoHS compliance, and endurance specified to 1,000 hours at 85 °C. Product status: End Of Life.

Key Features

• Capacitance and Voltage — 820 µF nominal capacitance with a rated voltage of 80 V and capacitance tolerance of ±20% (measured at 120 Hz, 20 °C).
• Audio‑Focused Grade — LKG series TYPE‑II (BK) grade intended for high‑grade audio equipment and HD audio applications, as specified in the LKG family documentation.
• Snap‑In Radial Package — Snap‑in terminal, radial can package for secure panel or chassis mounting (φ20 × 35 mm / 2.0 × 3.5 cm).
• Ripple and Leakage — Rated ripple current of 2.05 A at 120 Hz and measured leakage current shown as 760 µA, supporting typical low‑frequency audio system demands.
• Thermal and Endurance — Operating temperature range −40 °C to +85 °C with endurance specified as 1,000 hours at 85 °C per the LKG series endurance criteria.
• Compliance and Marking — RoHS compliant; product marking is printed in gold color on a black sleeve as defined in the series documentation.

Typical Applications

• High‑Grade Audio Equipment — Suited for use in designs where the LKG series audio‑optimized characteristics support high‑fidelity sound reproduction.
• HD Audio Systems — Applicable to HD audio components that require polarized aluminum electrolytic capacitors with defined ripple handling and endurance at elevated temperatures.
• Chassis and Rack‑Mounted Electronics — Snap‑in, radial can package enables robust mounting in panel and chassis assemblies common in professional audio gear.

Unique Advantages

• Audio‑oriented grade (TYPE‑II) — Series grading (BK) targets audio applications where tonal quality and fidelity are a focus.
• High ripple capability — 2.05 A ripple current at 120 Hz supports low‑frequency audio power handling requirements.
• Defined endurance — 1,000 hours at 85 °C provides a clear, manufacturer‑specified life metric for thermal stress planning.
• Compact snap‑in form factor — φ20 × 35 mm radial can with snap‑in terminals simplifies mounting in constrained audio enclosures and racks.
• RoHS compliant — Meets RoHS directive requirements as noted in the LKG series documentation.
