LKG1C472MESCCK

The LKG1C472MESCCK from Nichicon is a snap‑in, aluminum electrolytic capacitor in the LKG series engineered for audio equipment. It pairs high capacitance (4,700 µF) with a 16 V rating and snap‑in radial can packaging for robust board mounting and power‑filtering duties.

Designed with audio applications in mind, this capacitor provides long‑term endurance and measured electrical characteristics—supporting designers who require stable smoothing and energy storage in high‑fidelity equipment.

Key Features

• Capacitance & Voltage: 4,700 µF rated at 16 V, with a tolerance of ±20% (measured at 120 Hz, 20°C).
• Low‑frequency ripple handling: Rated ripple current of 2.6 A at 120 Hz for effective power supply smoothing in low‑frequency audio circuits.
• Loss and measurement: Tangent of loss angle (tanδ) specified as 0.25 with measurement condition 20°C, 120 Hz for predictable performance in audio signal paths.
• Leakage current: Specified leakage current of 820 µA, useful for estimating quiescent current in standby or idle states.
• Endurance and temperature range: Life rating of 1,000 hours at 85°C; operating range −40°C to +85°C for deployment across typical indoor and studio environments.
• Package & mounting: Snap‑in radial can (φ35 × 25 mm length) provided in tray packing for secure, repeatable PCB installation.
• Polarized design: Polarized aluminum electrolytic construction for bulk energy storage and decoupling in DC power stages.
• Regulatory: RoHS compliant.

Typical Applications

• High‑fidelity audio amplifiers — Bulk filtering and smoothing on amplifier power rails to support low‑noise audio performance.
• Audio power supplies — Energy storage and ripple reduction in linear and switching power supplies serving audio electronics.
• Professional audio equipment — Use in mixers, preamps and studio gear where stable capacitance and defined loss characteristics matter.

Unique Advantages

• High bulk capacitance in a compact can: 4,700 µF in a φ35 × 25 mm package provides substantial energy storage while conserving PCB area.
• Snap‑in radial mounting: Secure mechanical retention and straightforward assembly for power supply sections and heavy‑current boards.
• Measured acoustic‑grade design intent: Part of the LKG audio‑focused series, specified for high‑fidelity equipment to prioritize audio performance attributes.
• Predictable electrical behavior: Specified tanδ and leakage current values at 20°C/120 Hz make it easier to model circuit behavior and idle losses.
• Endurance under elevated temperature: 1,000‑hour rating at 85°C supports stable long‑term operation in thermally demanding enclosures.
• RoHS compliant and tray packed: Environmentally compliant and supplied in tray packing for production readiness.
