The LKG1K472MESCBK is an aluminum electrolytic, snap‑in terminal capacitor from Nichicon's LKG series, engineered for audio applications. It delivers high bulk capacitance and an 80 V rated voltage in a radial, snap‑in can package suited to high‑fidelity audio equipment.

Designed with audio performance in mind, this part combines large energy storage (4.7 mF) with a measured tan δ of 0.25 and a 120 Hz ripple current rating, providing characteristics useful for power handling and signal stability in HD audio designs.

Key Features

• Capacitance & Voltage — 4700 µF rated capacitance at 80 V provides substantial energy storage for demanding audio circuits.
• Audio‑Focused Construction — Part of Nichicon’s LKG series designed “For Audio Use,” intended to prioritize fidelity for high‑grade and HD audio equipment.
• Snap‑In Radial Can Package — Snap‑in terminals in a radial can (φ35 × 50 mm) enable secure chassis mounting for power applications.
• Loss Angle (tan δ) — Specified tan δ of 0.25 (measurement conditions per series data), supporting stable performance at audio frequencies.
• Ripple Current Capability — 4.85 A at 120 Hz rating to support AC ripple handling in power sections common to audio designs.
• Leakage Current — Rated leakage current listed at 1830 µA, consistent with electrolytic performance expectations for the capacitance/voltage class.
• Temperature & Lifetime — Operates from −40 °C to +85 °C with an endurance rating of 1000 hours at 85 °C.
• Environmental Compliance — RoHS‑compliant construction.

Typical Applications

• High‑Fidelity Audio Amplifiers — Bulk reservoir and filtering in amplifier power supplies where high capacitance and high voltage are required.
• Professional Audio Equipment — Designed for use in high‑grade audio systems and HD audio devices that prioritize sound quality.
