LKG1E472MESYBK

The LKG1E472MESYBK is a Nichicon LKG series aluminum electrolytic snap‑in capacitor specified at 4.7 mF (4700 µF) and 25 V. Engineered for audio equipment, this snap‑in radial can offers high capacitance and rated ripple handling for power‑stage and filtering applications in high‑grade audio systems.

Built to the LKG series audio grade specification (TYPE‑II / Gold Tune), this capacitor combines large capacitance, defined loss characteristics, and a compact φ20 × 45 mm can for use where audio performance and reliable smoothing are required within an operating range of -40 °C to +85 °C.

Key Features

• Capacitance and Voltage — 4.7 mF (4700 µF) rated at 25 V with ±20% tolerance (120 Hz, 20 °C), providing substantial energy storage for audio power stages.
• Audio‑Grade Construction — Designated TYPE‑II (Gold Tune) in the LKG series, optimized for high‑grade audio equipment and high‑fidelity sound applications.
• Low Loss — Specified tangent of loss angle (tan δ) of 0.3 (measured at 120 Hz, 20 °C), supporting predictable AC performance in audio circuits.
• Ripple Current Capability — Rated ripple current of 2.3 A at 120 Hz, suitable for smoothing and decoupling in audio power supplies.
• Leakage Current — Product-level leakage current listed as 1020 µA; series leakage guidance follows the datasheet formula for verification conditions.
• Durability and Temperature Range — Operates from -40 °C to +85 °C with an endurance rating of 1000 hours at 85 °C.
• Mounting and Package — Snap‑in radial can (φ20 × 45 mm) for robust chassis or PCB mounting; supplied in tray packing.
• Marking and Finish — Gold-color print on a black sleeve, consistent with the LKG series audio-grade aesthetic.

Typical Applications

• High‑Fidelity Amplifiers — Bulk smoothing and power supply decoupling where 4700 µF and 2.3 A ripple capability help maintain steady supply rails for low‑noise audio output.
• Audio Power Supplies — Energy storage and ripple absorption in audio power stages, benefiting from the LKG series' audio‑focused construction and loss characteristics.
• High‑Grade Consumer Audio Equipment — Use in premium audio components that require audio‑oriented electrolytic capacitors, leveraging the TYPE‑II Gold Tune designation.

Unique Advantages

• Audio‑Focused Design: Type‑II (Gold Tune) LKG series construction targets high‑grade audio equipment, aligning capacitor behavior with fidelity requirements.
• Large Capacitance in Compact Can: 4700 µF in a φ20 × 45 mm snap‑in can delivers significant energy density while minimizing board or chassis footprint.
• Measurable AC Performance: Specified tan δ (0.3 at 120 Hz, 20 °C) and ripple current rating provide quantifiable parameters for power‑stage design and simulation.
• Temperature and Endurance Ratings: Rated for -40 °C to +85 °C with 1000 hours endurance at 85 °C, allowing designers to plan for defined lifetime behavior under typical audio equipment thermal conditions.
• Clear Series Identification: Gold printing on a black sleeve and LKG series marking make part identification straightforward during assembly and service.
