LKG1J472MESBAK

The LKG1J472MESBAK is a snap‑in, aluminum electrolytic capacitor in Nichicon’s LKG series engineered for audio equipment. It provides 4700 µF capacitance at a 63 V rating in a radial can snap‑in package intended for high‑fidelity audio applications.

Key value comes from audio‑focused design and robust electrical characteristics: high capacitance for energy storage and smoothing, a rated ripple current specification for power handling, and a 1000‑hour endurance at 85°C for reliable operation in demanding audio electronics.

Key Features

• Capacitance & Voltage — 4700 µF nominal capacitance with a 63 V rated voltage and ±20% tolerance, suited for bulk energy storage and power filtering in audio circuits.
• Audio‑Oriented Design — Part of the LKG series designed specifically for high‑grade audio equipment and HD audio applications, prioritizing performance characteristics relevant to sound quality.
• Mounting & Package — Snap‑in terminal, radial can (φ30 × 40 mm / 3.0 × 4.0 cm), tray packing; intended for secure, through‑chassis installation in power sections.
• Electrical Loss & Ripple — Specified tangent of loss angle (tan δ) of 0.3 (measured at 120 Hz, 20°C) and a ripple current rating of 3.1 A at 120 Hz for reliable AC performance.
• Leakage Current — Leakage current specified at 1630 µA for this part; series guidance defines leakage after 5 minutes as not more than 3√(C·V) (µA), measured at 20°C.
• Temperature & Endurance — Operating range −40°C to +85°C with a rated lifetime of 1000 hours at 85°C; endurance criteria require capacitance change within ±20% and tan δ within 200% of initial values after the endurance test.
• RoHS Compliant — Conforms to RoHS directive per series documentation.
• Product Status — Listed as End of Life (EOL) for planning and procurement consideration.

Typical Applications

• High‑Fidelity Audio Amplifiers — Bulk filtering and power supply smoothing where 4700 µF at 63 V helps maintain stable rail voltages under dynamic audio loads.
• Studio and Professional Audio Equipment — Power supply decoupling in equipment aiming for high tonal quality as described for the LKG series.
• HD Audio Systems — Energy reservoir and ripple suppression in systems targeting improved audio performance, consistent with the LKG series’ audio focus.

Unique Advantages

• Audio‑focused engineering: Designed within the LKG series for high‑grade and HD audio equipment, aligning component characteristics with audible performance priorities.
• High bulk capacitance at elevated voltage: 4700 µF at 63 V supplies substantial energy storage for power rails and transient demands in audio power stages.
• Robust ripple handling: 3.1 A ripple current (120 Hz) offers headroom for common audio power supply conditions and reduces heating under AC stress.
• Stable across temperature: Specified performance from −40°C to +85°C and defined low‑temperature impedance ratios (series data) support predictable behavior in varied environments.
• Endurance‑tested specification: 1000 hours at 85°C endurance with defined limits on capacitance, tan δ, and leakage provides a clear reliability baseline for design planning.
• RoHS compliance: Meets environmental directive requirements noted in the series documentation for use in regulated markets.
