LKG1K272MESBAK

The LKG1K272MESBAK is a snap‑in aluminum electrolytic capacitor from Nichicon’s LKG series, optimized for audio equipment and high‑fidelity applications. It delivers 2.7 mF (2700 µF) capacitance at an 80 V rating in a radial snap‑in can package designed for robust power‑filtering and decoupling duties.

Designed for high‑grade audio use, this part combines a high ripple current capability, defined leakage and loss characteristics, and a 1000‑hour endurance at elevated temperature to support reliable operation in demanding audio power supplies and amplifier circuits.

Key Features

• Capacitance & Tolerance — 2.7 mF (2700 µF) with a tolerance of ±20% at 120 Hz, 20°C.
• Rated Voltage — 80 V working voltage suitable for higher‑voltage audio power rails.
• Low‑frequency Ripple Handling — 2.8 A ripple current at 120 Hz, enabling effective smoothing in power supplies.
• Leakage Current — Specified leakage current of 1390 µA after voltage application conditions noted in the datasheet.
• Loss Tangent (tan δ) — tan δ = 0.25 measured at 20°C, 120 Hz (80 V condition), providing a defined dissipation factor for design calculations.
• Endurance — Rated for 1000 hours at 85°C with post‑test limits on capacitance change, tan δ, and leakage current as specified by the series endurance requirements.
• Operating Temperature Range — −40°C to +85°C for broad ambient operation.
• Package & Mounting — Radial, can – snap‑in package; physical size φ30 × 35L and supplied in tray packing for board assembly.
• Audio‑Focused Design — LKG series is described for high‑grade audio equipment and prioritizes fidelity in power supply applications.
• RoHS Compliance — Series documentation indicates compliance with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• High‑fidelity audio amplifiers — Used for power supply smoothing and bulk energy storage to support clean, stable supply rails in audio amplifier designs.
• Audio power supplies — Serves as a filter/decoupling capacitor on higher‑voltage supplies in professional or consumer audio equipment.
• Signal decoupling in audio systems — Provides local energy reservoir and ripple attenuation for audio circuits where stable voltage under dynamic load is required.

Unique Advantages

• High ripple current capability: 2.8 A (120 Hz) rating supports effective ripple attenuation and reduces voltage excursion under load.
• Defined dissipation and leakage metrics: tan δ = 0.25 (20°C, 120 Hz, 80 V) and a specified leakage current of 1390 µA provide predictable electrical behavior for design validation.
• Endurance at elevated temperature: 1000 hours at 85°C lets designers account for long‑term performance in warm enclosures or tightly packed assemblies.
• Wide operating temperature range: −40°C to +85°C supports deployment across a broad set of ambient conditions common in audio equipment.
• Audio‑oriented series design: LKG series emphasis on high‑grade audio use means the part’s mechanical and electrical characteristics are aligned with fidelity‑focused power systems.
• Tray packing for assembly: Supplied in tray packing to support organized handling and board‑level placement workflows.
