LKG1K472MESBAK

The LKG1K472MESBAK is a snap‑in, radial aluminum electrolytic capacitor from Nichicon’s LKG series, optimized for audio equipment. It provides 4.7 mF (4700 µF) capacitance at an 80 V rated voltage and is configured for snap‑in mounting in power supply and filtering roles.

Key electrical attributes include a low‑frequency ripple current rating of 3.85 A (120 Hz), a dissipation factor (tan δ) of 0.25 at 20 °C/120 Hz, a rated leakage current of 1830 µA, and a rated endurance of 1000 hours at 85 °C. Status: End Of Life.

Key Features

• Capacitance & Voltage: 4700 µF (4.7 mF) nominal capacitance with an 80 V rated voltage, suitable for high‑voltage audio power rails and bulk energy storage.
• Audio‑Focused Design: Part of the LKG series specified "For Audio Use" and designed for high‑grade audio equipment and HD audio performance priorities.
• Ripple Handling: Low‑frequency ripple current rating of 3.85 A at 120 Hz to support smoothing and decoupling in low‑frequency power stages.
• Dissipation & Leakage: Tangent of loss angle (tan δ) = 0.25 (measured at 20 °C, 120 Hz) and leakage current of 1830 µA for predictable electrical behavior in audio circuits.
• Thermal & Endurance: Rated operating temperature range −40 °C to +85 °C with endurance specified as 1000 hours at 85 °C under rated voltage.
• Package & Mounting: Radial can, snap‑in terminal type with physical size φ30 × 45 L (approx. L: 4.5 × D: 3.0 cm); supplied in tray packing for assembly handling.
• RoHS Compliant: Conforms to RoHS directive as indicated in series documentation.

Typical Applications

• High‑Fidelity Audio Amplifiers: Bulk filtering and supply stabilization on high‑voltage amplifier rails to support stable low‑frequency performance.
• Audio Power Supplies: Energy storage and ripple smoothing in linear and regulated supplies serving audio circuits and preamplifiers.
• Professional Audio Equipment: Use in mixers, signal processing racks, and other high‑grade audio gear where stable capacitance and controlled dissipation matter.

Unique Advantages

• High Voltage Capability: 80 V rating enables use in higher‑headroom audio power rails without series stacks or derating.
