LKG1V183MESCAK

The LKG1V183MESCAK is a snap‑in aluminum electrolytic capacitor from Nichicon’s LKG series, engineered for audio equipment applications. It combines large capacitance with audio‑focused design characteristics from the LKG family to support power filtering and energy buffering in high‑fidelity audio systems.

Key electrical and mechanical attributes include 18,000 µF capacitance at 35 V, a low‑frequency ripple current rating of 4.15 A (120 Hz), and rated operation across −40 °C to +85 °C. The part is supplied in tray packing and is listed as End Of Life.

Key Features

• Capacitance & tolerance — 18,000 µF nominal capacitance with a tolerance of −20% to +20% (measured at 120 Hz, 20 °C), providing substantial bulk energy storage for power rails.
• Rated voltage — 35 V working voltage suitable for mid‑range audio power supplies and amplifier rails.
• Power handling — Low‑frequency ripple current 4.15 A at 120 Hz and specified tanδ (DF) 0.3 at 20 °C, 120 Hz, supporting sustained ripple conditions in audio power applications.
• Leakage current — Specified leakage current of 2,380 µA after rated voltage application (measurement condition per datasheet), allowing predictable bias behavior.
• Audio‑oriented series design — Part of the LKG family developed “for audio use,” with series documentation emphasizing tone quality and sound fidelity considerations.
• Reliability — Endurance specification of 1,000 hours at 85 °C with limits on capacitance change, tanδ, and leakage current as defined in the series datasheet.
• Package & mounting — Snap‑in radial can (φ35 × 40 mm length) designed for secure board mounting; supplied in tray packing for batch assembly.
• Environmental compliance — RoHS‑compliant per product data.

Typical Applications

• High‑fidelity audio amplifiers — Bulk filtering and power reservoir for amplifier supply rails where large capacitance and stable ripple performance are required.
• Audio power supplies — Energy storage and smoothing in regulated and unregulated audio equipment power stages.
• Professional audio gear — Support for mixing consoles, studio processors, and other pro‑audio equipment where the LKG series’ audio‑focused design is specified.

Unique Advantages

• Large energy storage: 18,000 µF nominal capacitance provides significant charge reservoir capacity for power‑supply stabilization in audio circuits.
• Defined ripple capability: 4.15 A low‑frequency ripple current rating at 120 Hz gives designers a quantifiable metric for thermal and ripple budgeting.
• Audio series pedigree: Part of Nichicon’s LKG family, which is documented as designed for high‑grade audio equipment and tone quality considerations.
• Operational temperature range: Rated for −40 °C to +85 °C, supporting deployment across common audio equipment thermal environments.
• Endurance specification: 1,000 hours at 85 °C endurance rating with post‑test limits on capacitance, tanδ, and leakage current to aid long‑term reliability planning.
• Tray packing: Supplied in tray packing to support organized handling and assembly for production workflows.
