LKG1K222MESBCK

The LKG1K222MESBCK is an aluminum electrolytic snap‑in capacitor from Nichicon's LKG series, optimized for audio equipment applications. It provides 2.2 mF (2200 µF) capacitance at an 80 V rating in a radial snap‑in can package (φ30 × 50 mm).

Designed with audio performance in mind, the LKG series targets high‑fidelity and HD audio applications. Key electrical characteristics for system design include a rated ripple current of 4.05 A (120 Hz), leakage current of 1,250 µA, tan δ of 0.2, and a 1,000‑hour endurance at 85 °C. Note: this specific part is marked End of Life.

Key Features

• Capacitance & Voltage — 2.2 mF (2200 µF) nominal capacitance with an 80 V rated voltage and ±20% tolerance, suitable where high capacitance at elevated voltage is required.
• Audio‑Focused Design — Part of the LKG series designed for high‑grade audio equipment and HD audio applications; the series emphasizes tone quality and sound fidelity.
• Ripple & Loss Characteristics — Rated ripple current 4.05 A at 120 Hz and tan δ specified at 0.2, enabling reliable AC load handling in audio power stages.
• Leakage Current — Specified leakage current of 1,250 µA for predictable bias behavior in DC‑coupled circuits.
• Endurance & Temperature Range — 1,000 hours life at 85 °C with specified stability after endurance testing; operating range −40 °C to +85 °C.
• Package & Mounting — Snap‑in lug radial can (φ30 × 50 mm) for secure chassis or terminal‑block mounting; polarized construction for correct DC orientation.
• RoHS Compliance — Compliant to RoHS directives as stated in the series documentation.

Typical Applications

• High‑Grade Audio Equipment — Use in premium audio amplifiers and components where the LKG series’ audio‑focused characteristics support tonal clarity and fidelity.
• HD Audio Systems — Filtering and energy storage in HD audio electronics that require stable capacitance and defined loss characteristics under load.
• Power Supply Reservoirs for Audio — Bulk capacitance and ripple handling for power rails in audio power stages and preamplifiers.

Unique Advantages

• High Voltage Capability: 80 V rating provides headroom for higher‑voltage audio circuits and supply architectures.
• Significant Capacitance in a Compact Can: 2.2 mF (2200 µF) in a φ30 × 50 mm snap‑in package reduces board area compared with multiple smaller capacitors.
• Designed for Audio Fidelity: The LKG series is explicitly developed for high‑grade audio use, prioritizing tonal quality as part of its design goals.
• Robust Ripple Handling: 4.05 A ripple current rating at 120 Hz supports sustained AC stress in power conversion and filtering stages.
• Predictable Endurance: 1,000 hours at 85 °C with defined limits for capacitance change, tan δ, and leakage current aids long‑term design planning.
• Regulatory Compliance: RoHS compliance supports use in regions requiring restriction of hazardous substances.
