LKG1E272MESYBK

The LKG1E272MESYBK is a snap-in aluminum electrolytic capacitor from Nichicon’s LKG series, offering 2700 µF capacitance at a 25 V rating in a radial can (φ20 × 30 mm). It is designed for audio applications and for use where substantial bulk capacitance and low-frequency ripple handling are required.

Key operational characteristics include a ripple current rating of 1.7 A (120 Hz), a tanδ of 0.3 (measured at 20°C, 120 Hz), and an endurance rating of 1000 hours at 85°C. The part is RoHS compliant and is currently listed as End Of Life.

Key Features

• Electrical Capacity — 2700 µF nominal capacitance with ±20% tolerance, providing bulk energy storage for filtering and decoupling in power sections.
• Rated Voltage — 25 V working voltage suitable for many low-voltage audio and power-supply circuits.
• Low-Frequency Ripple Handling — Rated ripple current of 1.7 A at 120 Hz to support audio power-supply smoothing and low-frequency load variations.
• Loss Characteristics — tanδ (dissipation factor) specified at 0.3 (20°C, 120 Hz) for predictable AC loss behavior in circuit design.
• Leakage and Endurance — Specified leakage current of 770 µA and an endurance rating of 1000 hours at 85°C with performance recovery to specified limits after restoration to 20°C.
• Package & Mounting — Snap-in radial can package (φ20 × 30 mm) for board insertion and mechanical stability, supplied in tray packing.
• Environmental Compliance — RoHS compliant, supporting lead-free assembly requirements.

Typical Applications

• Audio Power Supply Filtering — Bulk capacitance for smoothing and decoupling supply rails in high-grade audio equipment.
• Amplifier Output Stages — Energy storage to support dynamic current demands in amplifier circuits that prioritize sound quality.
• Power Rail Stabilization — Stabilizes low-voltage DC rails in electronic equipment where 25 V ratings and substantial capacitance are required.

Unique Advantages

• High Bulk Capacitance in Compact Can — 2700 µF in a φ20 × 30 mm package enables significant energy storage where board space is limited.
• Audio-Focused Design — Part of Nichicon’s LKG series developed for audio equipment, aligning product characteristics with high-fidelity use cases.
• Predictable AC Performance — Specified tanδ and ripple current values allow engineers to model dissipation and thermal behavior under 120 Hz conditions.
• Durability at Elevated Temperature — 1000-hour endurance at 85°C supports designs exposed to sustained elevated operating temperatures.
• RoHS Compliance — Conforms to RoHS requirements for lead-free electronic manufacturing.
