LKG2A821MESACK

The LKG2A821MESACK is an aluminum electrolytic snap‑in capacitor from the Nichicon LKG series designed for audio equipment. It pairs 820 µF capacitance with a 100 V rating in a compact radial can (φ25 × 40 mm) snap‑in package suited to high‑fidelity audio designs.

Engineered for audio applications, this capacitor delivers specified low‑frequency ripple handling and controlled dissipation (tanδ) while meeting RoHS requirements and operating across −40 °C to +85 °C with a 1000‑hour endurance at 85 °C.

Key Features

• Capacitance & Voltage — 820 µF rated capacitance at 100 V, tolerance ±20% (120 Hz, 20 °C).
• Audio‑Focused Design — Part of the LKG series developed for high‑grade and HD audio equipment with emphasis on fidelity.
• Low‑Frequency Ripple Handling — Rated low‑frequency ripple current of 3.0 A at 120 Hz for reliable performance under audio power conditions.
• Dissipation Factor (tanδ) — Specified tanδ of 0.2 (measurement at 120 Hz, 20 °C), supporting predictable loss characteristics in signal and power circuits.
• Leakage Current — Leakage current specified at 850 µA (measured after rated voltage application), providing predictable bias behavior.
• Package & Mounting — Snap‑in radial can (φ25 × 40 mm) for secure board mounting in equipment chassis or power assemblies.
• Operating Range & Endurance — Rated for −40 °C to +85 °C with a life/endurance of 1000 hours at 85 °C.
• Compliance & Marking — RoHS‑compliant; LKG series marking is printed in gold on a black sleeve.
• Packing — Supplied in tray packing for boardroom and production handling.

Typical Applications

• High‑grade audio equipment — Suited to systems where components are selected to support high‑fidelity sound reproduction.
• HD audio systems — Designed as part of the LKG family for designs that prioritize audio quality and stable performance.
• Audio electronics assemblies — Appropriate for assemblies requiring a high‑capacitance, high‑voltage snap‑in electrolytic solution with specified ripple handling and endurance.

Unique Advantages

• High voltage and capacitance in a compact snap‑in form: 820 µF at 100 V in a φ25 × 40 mm radial can enables high energy storage in constrained layouts.
• Audio‑oriented specification: LKG series design prioritizes tone quality and fidelity for high‑grade audio applications.
• Predictable ripple and loss characteristics: 3.0 A low‑frequency ripple current rating and tanδ = 0.2 help designers size power and filter stages with confidence.
• Engineered endurance: Specified 1000 hours at 85 °C provides a defined operating life metric for reliability planning.
• RoHS compliant: Meets RoHS directive requirements for environmental and regulatory consistency in assemblies.
