LKG1K182MESZAK

The LKG1K182MESZAK is an aluminum electrolytic, snap‑in terminal capacitor from Nichicon’s LKG series, specified at 1.8 mF (1800 µF) and 80 V. It is designed for high‑grade audio equipment where fidelity and stable power delivery are priorities.

This part uses the LKG TYPE‑I grade (Gold Tune) construction—a low‑profile, high‑tone‑quality design incorporating a new development electrolyte—and is supplied in a radial, can (snap‑in) package suited for board mounting in audio power and signal systems.

Key Features

• Capacitance & Voltage – Rated capacitance 1.8 mF (1800 µF) with a rated voltage of 80 V and tolerance ±20% (at 120 Hz, 20°C), providing bulk energy storage for audio power rails.
• Audio‑grade TYPE‑I (Gold Tune) – TYPE‑I classification: a low‑profile, high‑tone‑quality grade that adopts a new development electrolyte to prioritize high‑fidelity sound characteristics.
• Electrical loss (tan δ) – Specified tan δ = 0.25 (measurement per series conditions: 120 Hz, 20°C), allowing designers to account for dissipation in audio circuits.
• Ripple handling – Rated ripple current 2.35 A at 120 Hz, suitable for smoothing and decoupling on audio power supplies and amplifier rails.
• Operating temperature & lifetime – Specified operating range −40°C to +85°C with an endurance rating of 1000 hours at 85°C, enabling reliable performance in typical audio equipment environments.
• Package & mounting – Snap‑in radial can package (lug/snap‑in terminal) for secure board mounting; physical size approximately 22 mm diameter × 40 mm length (L: 4.0 cm × D: 2.2 cm).
• Polarity and marking – Polarized electrolytic capacitor; sleeve marked in gold color on a black sleeve according to series marking practice.
• Environmental compliance – RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• High‑grade audio amplifiers – Bulk decoupling and power smoothing on amplifier rails where stable supply energy supports low‑distortion performance.
• Professional audio equipment – Power supply filtering and energy storage in mixers, studio processors and other professional systems demanding high‑fidelity playback.
• HD Audio systems – Supporting digital‑analog power domains and local energy buffering to maintain signal integrity in high‑resolution audio devices.
• Audio power supplies – Ripple suppression and reservoir capacitance in regulated and discrete power supply stages for consumer and pro audio electronics.

Unique Advantages

• Audio‑focused materials and construction – TYPE‑I Gold Tune grade and the new electrolyte formulation target tonal quality and performance important to high‑fidelity designs.
• Compact snap‑in package – Radial can with snap‑in terminals simplifies PCB mounting for power sections while saving board space thanks to its low profile.
• Measurable loss specification – Specified tan δ value (0.25 at 120 Hz, 20°C) helps engineers predict dissipation and thermal behavior in audio circuits.
• Robust ripple capability – 2.35 A ripple current rating at 120 Hz provides the ability to handle dynamic supply currents common in audio amplifiers.
• Wide operational envelope – −40°C to +85°C operating range and 1000‑hour endurance at 85°C support long‑term operation in typical equipment environments.
• Regulatory compliance – RoHS conformity helps meet environmental and procurement requirements for commercial and professional audio products.
