LKG1K821MESYAK

The LKG1K821MESYAK is an aluminum electrolytic capacitor in a snap‑in radial can designed for high‑grade audio equipment. It is a Type‑I, low‑profile, high tone quality grade that uses Nichicon’s newly developed electrolyte to prioritize high‑fidelity sound quality.

With an 820 µF capacitance at 80 V rating, polarized construction, and snap‑in mounting, this part is suited for power supply smoothing and decoupling in demanding audio applications where tonal quality and reliable electrical performance matter.

Key Features

• Audio‑focused Type‑I construction — Low‑profile, high tone quality grade designed specifically for high‑grade and HD audio equipment.
• Nominal electrical values — 820 µF capacitance at 80 V rated voltage with ±20% tolerance (‑20% to +20%).
• Ripple handling — Rated ripple current of 1.7 A at 120 Hz for low‑frequency filtering and smoothing duties.
• Temperature and endurance — Operating range −40 to +85°C with an endurance rating of 1000 hours at 85°C under rated voltage.
• Leakage current specification — After 5 minutes at rated voltage and 20°C, leakage current conforms to the datasheet limit (≤ 3√CV μA, where C is μF and V is volts).
• Mechanical package — Snap‑in, radial can package for secure board retention; dimensions L: 2.5 × D: 2.0 cm with seated height up to 2.5 cm.
• Identification and compliance — Marked with gold lettering on a black sleeve and compliant with RoHS (2011/65/EU, (EU)2015/863).
• Low‑temperature impedance behavior — Characterized impedance ratios for low temperature performance (Z(−25°C)/Z(+20°C) and Z(−40°C)/Z(+20°C) specified in the datasheet).

Typical Applications

• High‑grade audio amplifiers — Power supply smoothing and decoupling to support high‑fidelity playback and low‑noise operation.
• HD audio systems — Component for designers targeting improved tone quality and reliable electrolytic performance in premium audio equipment.
• Audio power supplies — Bulk filtering and ripple reduction where a snap‑in radial mounting is preferred for mechanical retention.

Unique Advantages

• Designed for audio fidelity: Type‑I low‑profile electrolyte formulation emphasizes tone quality for high‑grade and HD audio designs.
• Robust ripple capability: 1.7 A at 120 Hz supports demanding low‑frequency filtering tasks in audio power stages.
• Temperature and life assurance: Specified for −40 to +85°C operation with 1000 hours endurance at 85°C under rated voltage for predictable long‑term behavior.
• Secure snap‑in mounting: Radial, snap‑in can package provides reliable board retention for through‑hole audio assemblies.
• Clear identification and compliance: Gold‑letter marking on a black sleeve and RoHS compliance simplify inspection and regulatory planning.
