LKG1K821MESBCK

The LKG1K821MESBCK is a snap‑in, radial can aluminum electrolytic capacitor from Nichicon’s LKG series, engineered for audio equipment where high‑fidelity performance is a priority. This 820 µF, 80 V polarized capacitor combines high capacitance with a compact φ30 × 25 mm form factor and is intended for power filtering and smoothing in audio power sections.

Key electrical parameters include a capacitance tolerance of ±20% (at 120 Hz, 20 °C), tanδ 0.2 (measured at 20 °C, 120 Hz), low‑frequency ripple current rating of 2.4 A (120 Hz) and a rated endurance of 1000 hours at 85 °C. Note: this part is designated End Of Life.

Key Features

• Capacitance & Voltage — 820 µF nominal capacitance with an 80 V rated voltage suitable for higher‑voltage audio power rails.
• Audio‑oriented design — Part of the LKG series specified "for audio equipment" and developed with emphasis on high‑fidelity sound quality.
• Loss and measurement — Specified tangent of loss angle (tanδ) of 0.2 at 20 °C, 120 Hz for predictable dissipation behavior in audio circuits.
• Ripple and leakage — Low‑frequency ripple current rating of 2.4 A at 120 Hz and a documented leakage current of 760 µA for stable power smoothing performance.
• Temperature and endurance — Operating range −40 °C to +85 °C with a rated life of 1000 hours at 85 °C under applied rated voltage.
• Mechanical & mounting — Snap‑in radial can package (φ30 × 25 mm) designed for secure PCB installation; supplied in tray packing.
• Regulatory — RoHS compliant.

Typical Applications

• High‑fidelity audio amplifiers — Bulk filtering and smoothing on power rails where stable capacitance and ripple handling support clean audio reproduction.
