LKG1K182MESCAK

The LKG1K182MESCAK is a snap‑in aluminum electrolytic capacitor from Nichicon’s LKG series, specified for audio applications. It delivers 1800 µF capacitance at an 80 V rating in a compact φ35 × 20 mm can with snap‑in mounting.

Designed for high‑fidelity audio equipment within the LKG family, this TYPE‑I (AK) grade part emphasizes tone quality while providing robust power filtering: 2.5 A low‑frequency ripple handling (120 Hz), controlled dissipation factor, and a wide operating temperature range of −40 °C to +85 °C.

Key Features

• Capacitance & Voltage — 1800 µF nominal capacitance with an 80 V rated voltage and ±20% tolerance, suitable for power smoothing and bulk energy storage in audio power supplies.
• Audio‑Oriented Grade (TYPE‑I / AK) — The part number suffix "AK" corresponds to the LKG TYPE‑I (Gold Tune) grade from the series, aimed at high‑tone quality in audio equipment.
• Ripple Current & Dissipation — Low‑frequency ripple current rating of 2.5 A (120 Hz) and a tangent of loss angle (tan δ) of 0.25 measured at 20 °C/120 Hz, enabling reliable ripple handling and predictable AC loss characteristics.
• Leakage Current — Specified leakage current of 1130 µA after standard application of rated voltage, providing a measurable baseline for power‑supply leakage budgeting.
• Operating Range & Endurance — Operating temperature range −40 °C to +85 °C with endurance defined as 1000 hours at 85 °C under rated voltage; meets the LKG series endurance criteria for stability over the specified life test.
• Mechanical & Mounting — Snap‑in radial can package (φ35 × 20 mm) for secure board retention and ease of assembly; supplied in tray packing for handling and component placement.
• Regulatory — RoHS compliant, aligning with current lead‑restriction requirements.

Typical Applications

• Audio Power Supplies — Bulk filtering and smoothing in amplifier and preamplifier supplies where high capacitance and 80 V rating are required.
• High‑Fidelity Audio Equipment — Tone‑focused applications that benefit from the LKG TYPE‑I grade characteristics and controlled dissipation factor.
• Power Filtering for Modular Systems — Local energy storage and ripple attenuation in modular audio or pro‑audio power distribution boards using snap‑in mounting for reliable retention.

Unique Advantages

• Audio‑grade tuning: The TYPE‑I (AK) grade designation targets tone quality, making the component suitable for designs prioritizing audio performance.
• High ripple handling: 2.5 A ripple current (120 Hz) supports robust AC ripple filtering in power supply stages, reducing stress on downstream circuitry.
• Compact, serviceable package: φ35 × 20 mm snap‑in can offers a balance of capacitance and board space for compact audio power designs while simplifying mechanical retention.
• Measured electrical baseline: Specified tan δ (0.25 at 20 °C/120 Hz) and leakage current (1130 µA) provide predictable electrical behavior for design verification and BOM comparison.
• RoHS compliance and tray packing: Environmentally compliant construction and tray packing facilitate handling and assembly in production environments.
• Defined endurance: 1000 hours at 85 °C with post‑test limits for capacitance, tan δ, and leakage current support lifecycle planning and reliability assessments.
