LKG1H472MESAAK

The LKG1H472MESAAK is a Nichicon LKG series aluminum electrolytic capacitor in a snap‑in radial can, engineered for high‑grade audio equipment where fidelity and stable power delivery matter. It delivers 4700 µF capacitance at a 50 V rating with a low‑profile TYPE‑I audio grade construction that emphasizes tonal quality through a specialized electrolyte.

Key physical and electrical characteristics include a 25 mm diameter × 35 mm length can, polarized snap‑in mounting, an operating range of -40 °C to +85 °C, and documented endurance of 1000 hours at 85 °C under rated voltage.

Key Features

• Capacitance & Rated Voltage — 4.7 mF (4700 µF) rated at 50 V with ±20% tolerance for bulk energy storage and low‑frequency smoothing in audio power rails.
• Audio‑focused Grade (TYPE‑I) — Classified as TYPE‑I (Gold Tune) low‑profile grade; utilizes a newly developed electrolyte intended to prioritize high tone quality for HD Audio equipment.
• Electrical Loss Characteristics — Specified tangent of loss angle (tan δ) of 0.3 (measurement context: 120 Hz, 20 °C), supporting predictable frequency‑domain performance in audio circuits.
• Ripple Current Capability — Rated ripple current of 2.7 A at 120 Hz, enabling handling of low‑frequency ripple and transient currents typical in amplifier and power supply applications.
• Package & Mounting — Radial can with snap‑in terminals for secure PCB installation and robust mechanical retention in power assemblies.
• Operating Temperature & Endurance — Specified operating range -40 °C to +85 °C with endurance validated to 1000 hours at 85 °C under rated voltage; capacitance change, tan δ and leakage current requirements are defined for post‑endurance recovery.
• Marking & Finish — Printed with gold‑color lettering on a black sleeve consistent with the LKG series audio aesthetic and identification.
• Environmental Compliance — RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• High‑grade audio amplifiers — Bulk filtering and energy reservoir to support dynamic transients and stable power delivery for improved audio playback fidelity.
• HD audio equipment power supplies — Smoothing and decoupling in regulated rails for DACs, preamps, and digital audio processors.
• Professional audio electronics — Power storage and ripple suppression in mixing consoles, studio gear, and other equipment where tonal consistency is prioritized.

Unique Advantages

• Audio‑centric electrolyte and construction — TYPE‑I (Gold Tune) specification and new electrolyte formulation focused on tone quality for HD Audio designs.
• Compact snap‑in form factor — 25 mm diameter × 35 mm length can in a snap‑in radial package simplifies board mounting while providing substantial capacitance density.
• Defined ripple performance — 2.7 A ripple current rating at 120 Hz supports low‑frequency power demands common in audio power sections.
• Wide temperature range with proven endurance — -40 °C to +85 °C operating range and 1000 hours endurance at 85 °C under rated voltage for reliable operation in demanding environments.
• Clear identification and finishing — Gold lettering on black sleeve for easy visual identification consistent with the LKG audio series.
• Regulatory compliance — RoHS compliance for use in designs requiring restricted‑substance adherence.
