LKG1H472MESCCK

The LKG1H472MESCCK is a snap-in aluminum electrolytic capacitor from Nichicon’s LKG series, offering 4,700 µF capacitance at a 50 V rating. Its radial, snap-in can configuration and Γ35 × 50 mm form factor provide a compact, PCB-friendly solution for power filtering in audio equipment.

Designed with audio performance in mind, the LKG series emphasizes high-fidelity sound characteristics and practical electrical endurance: a low-frequency ripple current rating of 3.9 A (120 Hz), a specified tanδ of 0.22 (measured at 20 °C, 120 Hz), and an endurance specification of 1,000 hours at 85 °C.

Key Features

• Capacitance and Tolerance — 4,700 µF capacitance with a tolerance of −20% to +20% at 120 Hz, 20 °C, suitable for bulk energy storage and decoupling.
• Voltage Rating — 50 V rated voltage for mid‑voltage power rails in audio and related electronics.
• Audio‑Oriented Design — Part of the LKG series “For Audio Use” and developed for high‑grade audio equipment with priority on high‑fidelity sound characteristics.
• Ripple Performance — Low‑frequency ripple current rating of 3.9 A at 120 Hz, useful for smoothing and power supply filtering in audio power stages.
• Loss Characteristics — tanδ (loss tangent) specified at 0.22 (20 °C, 120 Hz, 50 V) for predictable dissipation behavior in audio circuits.
• Reliability and Endurance — Endurance rating: 1,000 hours at 85 °C with defined limits on capacitance change, tanδ, and leakage current after test.
• Environmental and Mounting — Polarized aluminum electrolytic in a radial, snap‑in can; RoHS compliant and supplied in tray packing for production handling.
• Operating Range and Size — Operating temperature −40 °C to +85 °C; physical size approximately φ35 × 50 mm (diameter × length).

Typical Applications

• High‑Fidelity Audio Amplifiers — Bulk filtering and power smoothing in amplifier power supplies where audio fidelity is prioritized.
• Professional Audio Equipment — Energy storage and decoupling in mixers, studio processors, and other pro‑audio electronics that demand stable performance.
• Hi‑Fi Consumer Electronics — Power rail filtering in high‑grade home audio components to help maintain signal integrity and low noise.

Unique Advantages

• Audio‑Focused Series Design — Part of Nichicon’s LKG family developed specifically “For Audio Use,” aligning electrical characteristics with high‑fidelity sound requirements.
• High Ripple Capability — 3.9 A ripple current rating at 120 Hz supports robust smoothing for audio power stages and reduces ripple‑related artifacts.
• Measured Loss Specification — tanδ defined at 0.22 (20 °C, 120 Hz, 50 V) gives designers a clear reference for dissipation and stability in circuit simulations and thermal planning.
• Compact Snap‑In Package — Radial snap‑in can (φ35 × 50 mm) enables secure PCB mounting and convenient assembly for through‑hole power modules.
• Defined Endurance — 1,000 hours at 85 °C specification provides a predictability margin for lifetime planning in continuous‑operation audio systems.
• RoHS Compliant — Meets RoHS requirements for environmental compliance in commercial and professional products.
