LKG2A272MESCBK

The LKG2A272MESCBK is a snap‑in, large‑can aluminum electrolytic capacitor from Nichicon's LKG series, designed specifically for audio equipment. This Type‑II (BK) Gold Tune variant prioritizes audio-grade performance while delivering high capacitance and voltage rating for power-supply and filtering applications in professional audio systems.

Key electrical characteristics include 2.7 mF (2700 µF) capacitance at 100 V, a low-frequency ripple current rating of 4.3 A (120 Hz), a tangent of loss angle (tan δ) of 0.25 measured at 20°C/120 Hz, and an endurance rating of 1000 hours at 85°C. Status: End Of Life.

Key Features

• High Capacitance and Voltage: 2.7 mF (2700 µF) rated at 100 V for bulk energy storage and smoothing on higher-voltage audio rails.
• Audio‑Focused Design: Part of the LKG series developed for high‑grade audio equipment; the BK code corresponds to the Type‑II Gold Tune grade intended to preserve tone quality.
• Ripple Current Handling: Low frequency ripple current of 4.3 A at 120 Hz, suitable for demanding power‑supply filtering in audio amplifiers and related gear.
• Electrical Loss and Leakage: tan δ = 0.25 (measured at 20°C, 120 Hz) and leakage current specified at 1550 µA, providing predictable electrical behavior for design calculations.
• Reliability and Endurance: Rated lifetime of 1000 hours at 85°C with an operating temperature range of −40°C to +85°C for stable long‑term operation under typical audio equipment conditions.
• Package & Mounting: Radial, snap‑in can (φ35 × 45 mm) for secure chassis or board mounting; supplied in tray packing to support assembly handling.
• Regulatory Compliance: RoHS‑compliant per the product data.

Typical Applications

• High‑fidelity audio power supplies: Bulk smoothing and energy storage for amplifier rails where large capacitance and 100 V rating are required.
• Professional audio amplifiers: Filtering and decoupling in power stages to support consistent audio performance and low noise.
• Studio and signal processing equipment: Power conditioning in racks and consoles where audio tone preservation is important.

Unique Advantages

• Audio‑grade tuning: Type‑II Gold Tune specification focuses on preserving tone quality for high‑fidelity applications.
• High energy density for 100 V systems: 2700 µF at 100 V provides substantial bulk capacitance in a compact large‑can package.
• Robust ripple capability: 4.3 A ripple current (120 Hz) helps manage dynamic loads in power supplies without excessive heating.
• Predictable electrical parameters: Specified tan δ and leakage figures support reliable modeling and selection for audio circuits.
• Durability under stress: 1000‑hour endurance at 85°C and −40°C to +85°C operating range support sustained performance in commercial audio environments.
• Tray packing for production: Supplied in trays to aid handling and reduce damage during assembly and storage.
