LKG1V472MESBCK

The LKG1V472MESBCK is a snap‑in, aluminum electrolytic capacitor designed for audio equipment. It pairs a 4,700 µF capacitance with a 35 V rating and is part of Nichicon’s LKG series engineered for high‑grade audio applications.

Key electrical and mechanical characteristics include a tanδ (DF) of 0.22 measured at 20°C/120 Hz, a low‑frequency ripple current rating of 3.55 A (120 Hz), leakage current of 1,210 µA, and an operating temperature range of −40°C to +85°C. The part is supplied in a radial, snap‑in can (φ30 × 50 mm) and is RoHS compliant.

Key Features

• Capacitance & Voltage — 4,700 µF nominal capacitance with a 35 V rated voltage and ±20% tolerance, suitable for bulk energy storage and smoothing in audio power stages.
• Audio‑Focused Design — Part of the LKG series developed specifically for audio equipment, prioritizing sound quality in high‑grade audio applications.
• Electrical Performance — Tangent of loss angle (tanδ) of 0.22 (measured at 20°C, 120 Hz) and a low‑frequency ripple current rating of 3.55 A at 120 Hz for sustained AC loading.
• Leakage Current — Specified leakage current of 1,210 µA, defined under the product’s measurement conditions.
• Robust Operating Range — Rated for operation from −40°C to +85°C with an endurance life of 1,000 hours at 85°C.
• Mounting & Package — Snap‑in, radial can package (φ30 × 50 mm) for secure chassis or PCB mounting and straightforward mechanical retention.
• Environmental Compliance — RoHS compliant as specified in the product documentation.

Typical Applications

• High‑fidelity audio amplifiers — Bulk filtering and power‑supply smoothing where large capacitance and stable performance at audio frequencies are required.
• Audio preamplifiers and processors — Energy storage and decoupling to support low‑noise analog stages in audio signal chains.
• Power supply modules for audio systems — Handling low‑frequency ripple current and providing local energy reserve for transient loads.

Unique Advantages

• Audio‑centric engineering — Part of the LKG family developed for audio use, providing specification data and construction choices aligned to high‑grade audio equipment.
• High capacitance in a compact snap‑in can — 4,700 µF in a φ30 × 50 mm snap‑in package supports space‑efficient board or chassis mounting.
• Measurable AC performance — Defined tanδ and ripple current ratings (0.22 at 20°C/120 Hz; 3.55 A at 120 Hz) allow designers to size capacitors against audio power demands.
• Wide operating temperature range — −40°C to +85°C rating and 1,000‑hour endurance at 85°C for predictable life in demanding thermal environments.
• Regulatory compliance — RoHS compliance supports use in designs targeting restricted‑substance requirements.
