LKG1C183MESZAK

The LKG1C183MESZAK is an aluminum electrolytic, snap‑in terminal capacitor from Nichicon's LKG series, specified at 18,000 µF and 16 V with a ±20% tolerance. It is engineered for high‑grade audio equipment and HD audio designs where large bulk capacitance, audio‑focused electrolyte formulation (TYPE‑I), and reliable power rail performance are required.

Packaged as a radial snap‑in can (22 mm diameter × 45 mm length), this polarized capacitor combines high capacitance with an audio‑oriented loss characteristic (tanδ = 0.35) and an operating temperature range of -40 °C to +85 °C.

Key Features

• Capacitance & Voltage — 18,000 µF rated capacitance at 16 V with ±20% tolerance for high bulk energy storage in low-voltage audio power rails.
• Audio-Grade Electrolyte (TYPE‑I) — Low‑profile, high‑tone quality electrolyte formulation targeted for high‑fidelity audio equipment.
• Electrical Loss — Specified tangent of loss angle (tanδ) of 0.35 (measurement at 120 Hz, 20 °C) to characterize AC loss behavior relevant to audio performance.
• Package & Mounting — Radial snap‑in can (snap‑in terminal) for secure chassis or board mounting; physical size L: 45 mm × D: 22 mm.
• Thermal & Lifetime — Rated for operation from -40 °C to +85 °C with an endurance rating of 1000 hours at 85 °C.
• Ripple Current — 2.8 A at 120 Hz, suitable for smoothing and filter duties in audio power supplies.
• Leakage Current Specification — After 5 minutes at rated voltage and 20 °C, leakage current is specified not more than 3√(C·V) µA (C: µF, V: volts).
• Environmental Compliance — RoHS compliant (2011/65/EU, (EU)2015/863).
• Marking — Gold color print on a black sleeve for clear identification.

Typical Applications

• High‑grade Audio Amplifiers — Bulk reservoir and smoothing capacitance for analog and power stages in high‑fidelity amplifier designs.
• HD Audio Equipment — Designed to meet the tone quality requirements of HD audio modules and consumer/professional audio gear.
• Professional Audio Systems — Local power supply filtering and energy buffering where high capacitance and audio‑focused characteristics are needed.

Unique Advantages

• Large Bulk Capacitance: 18,000 µF provides substantial energy storage for low‑voltage audio rails, reducing ripple and supporting dynamic audio demands.
• Audio‑Focused Electrolyte: TYPE‑I low‑profile electrolyte formulation prioritizes high‑tone quality for applications where sound fidelity is a design goal.
• Snap‑in Mounting: Radial snap‑in can simplifies mechanical retention for chassis or board assemblies while providing a secure connection for high‑current paths.
• Operating Range & Endurance: -40 °C to +85 °C rating with 1000 hours endurance at 85 °C supports sustained operation in typical audio equipment environments.
• Designed for Audio Performance: Specified tanδ and ripple current at 120 Hz tie directly to behavior under audio power conditions, allowing engineers to evaluate suitability against system requirements.
• Regulatory Compliance: RoHS compliance supports use in designs targeting restricted‑substance directives.
