LKG1C472MESACK

The LKG1C472MESACK is a snap‑in, radial aluminum electrolytic capacitor in Nichicon’s LKG series, purpose‑built for high‑grade audio equipment where fidelity is a priority. This TYPE‑I (Gold Tune) part pairs a 4.7 mF capacitance with a 16 V rated voltage and a low loss tangent to support audio power filtering and decoupling in premium audio designs.

Its mechanical snap‑in can package (φ25 × 40 mm) and audio‑focused electrolytic formulation deliver a compact, serviceable solution for professional and consumer audio power systems that require reliable performance across the specified operating range.

Key Features

• Capacitance & Voltage — 4700 µF (4.7 mF) nominal capacitance with a 16 V rated voltage and ±20% tolerance, providing bulk energy storage and smoothing for audio power rails.
• Audio‑Grade Electrolyte (TYPE‑I) — Designed for high‑grade audio equipment with a TYPE‑I (Gold Tune) electrolyte formulation focused on high tone quality.
• Low Loss — Specified tan δ of 0.25 (measurement frequency: 120 Hz, 20 °C), supporting lower dissipation in signal‑sensitive audio circuits.
• Package & Mounting — Radial can, snap‑in terminal configuration for secure, serviceable board mounting in power supply assemblies; nominal dimensions φ25 × 40 mm.
• Reliability & Lifetime — Rated for operation from −40 °C to +85 °C with an endurance specification of 1000 hours at 85 °C.
• Ripple Handling — Ripple current rating of 2.7 A at 120 Hz, suitable for audio supply filtering and regulator smoothing duties.
• Leakage Current Specification — After 5 minutes at rated voltage and 20 °C, leakage current is specified as not more than 3√(C×V) µA (C in µF, V in V), per the series specification.
• RoHS Compliant — Conforms to RoHS directive requirements (2011/65/EU, (EU)2015/863).

Typical Applications

• High‑End Audio Amplifiers — Bulk filtering and decoupling on power rails to support high‑fidelity amplification stages.
• AV Receivers and Preamp Power Supplies — Energy storage and ripple suppression where low loss and audio‑grade characteristics are required.
• Professional Mixers and Signal Processing Gear — Stable power filtering to preserve signal integrity in demanding multi‑channel systems.

Unique Advantages

• Engineered for Audio Fidelity: TYPE‑I electrolyte and a low tan δ of 0.25 provide reduced dissipation that supports sonic clarity in audio power circuits.
• Compact Snap‑In Form Factor: φ25 × 40 mm radial can with snap‑in terminals simplifies installation for power assemblies while saving board area.
• Measured Ripple Capability: 2.7 A ripple current at 120 Hz enables reliable filtering performance in typical audio power supply environments.
• Wide Operating Range and Endurance: −40 °C to +85 °C operation and 1000‑hour endurance at 85 °C give predictable lifetime behavior under rated conditions.
• Defined Leakage Characteristics: Leakage limited to 3√(C×V) µA after initial charge provides a quantifiable parameter for design verification.
• Regulatory Compliance: RoHS compliance supports environmental and regulatory requirements for modern electronic products.
