LKG1E562MESBCK

The LKG1E562MESBCK is an aluminum electrolytic, snap‑in terminal capacitor from Nichicon’s LKG series, designed specifically for high‑grade audio equipment and HD audio applications. It delivers 5.6 mF (5600 µF) at 25 V in a compact radial can (φ30 × 45 mm) with snap‑in mounting and tray packing.

Key electrical characteristics include a low loss tangent (tanδ 0.22 at 20°C, 120 Hz), a rated low‑frequency ripple current of 3.5 A (120 Hz), a measured leakage current of 1120 µA, and a 1000‑hour endurance rating at 85°C. The component is RoHS compliant and polarized for typical audio power supply use.

Key Features

• Capacitance & Voltage — 5600 µF nominal capacitance at a rated voltage of 25 V with ±20% tolerance (measured at 120 Hz, 20°C).
• Low Loss for Audio — Tangent of loss angle (tanδ) of 0.22 measured at 20°C, 120 Hz, supporting low‑loss performance in audio circuits.
• High Ripple Handling — Low‑frequency ripple current rating of 3.5 A at 120 Hz for demanding supply conditions in audio applications.
• Leakage Current — Specified leakage current of 1120 µA (per product specification).
• Reliability & Endurance — Endurance rating of 1000 hours at 85°C; after the endurance test the capacitor meets capacitance, tanδ and leakage specifications defined in the datasheet.
• Temperature Range — Operating range from −40°C to +85°C for broad environmental tolerance.
• Mounting & Package — Snap‑in radial can package (φ30 × 45 mm; L: 4.5 × D: 3 cm), designed for snap‑in mounting and supplied in tray packing.
• Low‑temperature Stability — Impedance ratios specified in the series datasheet: Z(−25°C)/Z(+20°C) ≤ 4 and Z(−40°C)/Z(+20°C) ≤ 12 (measurement frequency: 120 Hz).
• Compliance — RoHS compliant (per product data).

Typical Applications

• Professional Audio Amplifiers — Intended for use in high‑grade audio equipment where large capacitance and controlled loss support sound quality.
• High‑Fidelity (Hi‑Fi) Systems — Suited to HD audio systems that require stable bulk capacitance and low tanδ at audio frequencies.
• Audio Power Supplies — Applicable in audio power supply stages in equipment that needs reliable ripple performance and endurance at elevated temperatures.

Unique Advantages

• Designed for audio fidelity: Tangent of loss angle (tanδ 0.22 at 20°C, 120 Hz) and the LKG series’ audio‑focused development support low‑loss performance for HD audio.
• High ripple capability: 3.5 A ripple current rating at 120 Hz helps handle demanding low‑frequency ripple in audio power stages.
• Robust endurance: 1000‑hour rating at 85°C with defined limits for capacitance change, tanδ and leakage ensures predictable long‑term behavior under thermal stress.
• Compact snap‑in package: φ30 × 45 mm radial can with snap‑in terminals provides a high‑capacitance solution in a space‑efficient form factor and simplifies mounting.
• Broad operating range: −40°C to +85°C operating temperature supports a wide variety of audio equipment environments.
• RoHS compliant: Meets RoHS directive requirements as stated in the product data.
