LKG1J472MESBBK

The LKG1J472MESBBK is an aluminum electrolytic, snap‑in terminal capacitor engineered for audio equipment. It combines high capacitance (4.7 mF / 4700 µF) with a 63 V rated voltage and is optimized for use where reliable power filtering and energy storage are required in high‑fidelity audio designs.

Designed with radial can snap‑in packaging and tray packing for board‑level assembly, this polarized capacitor delivers measurable performance attributes—ripple current handling, low loss (tan δ), and thermal endurance—targeted at audio applications that require stable power delivery and long operational life.

Key Features

• Capacitance & Voltage — 4700 µF (4.7 mF) nominal capacitance with a 63 V rated voltage and ±20% tolerance for bulk energy storage and smoothing in power rails.
• Low Loss Characteristic — Specified tan δ of 0.3 (measurement at 120 Hz, 20°C) to help minimize dissipation in audio power paths.
• High Ripple Current — Rated ripple current of 3.8 A at 120 Hz to support dynamic load conditions common in amplifier power supplies.
• Leakage Current — Leakage current value provided (approximately 1630 µA) for predictable quiescent behavior during system design and bias calculations.
• Reliability & Lifetime — Endurance rating of 1000 hours at 85°C with restored characteristics within specified limits after the test, supporting sustained operation in warm enclosure environments.
• Operating Temperature — Specified range of −40°C to +85°C for broad ambient compatibility in electronic equipment.
• Package & Mounting — Snap‑in, radial can configuration (φ30 × 50 mm) for secure mechanical mounting and straightforward PCB assembly; supplied in tray packing.
• Environmental Compliance — RoHS‑compliant construction for regulatory alignment in commercial electronics.

Typical Applications

• High‑Fidelity Audio Amplifiers — Bulk energy storage and power supply smoothing to support transient output demands and reduce audible noise.
• Preamp and Signal Conditioning Power Rails — Stable decoupling for analog front ends where consistent supply behavior contributes to sound quality.
• Audio System Power Supplies — Reservoir and filter capacitor in linear or regulated supplies that need high capacitance at elevated voltages.

Unique Advantages

• Audio‑Focused Design — Series design emphasizes high fidelity use, making the part suitable for audio equipment where sound quality is a priority.
• Large Capacitance in Compact Can — 4700 µF in a φ30 × 50 mm radial can provides significant energy density for space‑constrained audio PCBs.
• High Ripple Handling — 3.8 A ripple current rating supports dynamic amplifier loads and reduces heating during heavy use.
• Predictable Loss and Leakage — Specified tan δ and leakage current figures enable accurate thermal and bias budgeting in design.
• Operational Endurance — 1000 hours at 85°C endurance specification provides a measurable reliability baseline for long‑life audio installations.
• RoHS Compliance — Meets RoHS requirements for environmentally regulated product builds.
