LKG1J822MESCAK

The LKG1J822MESCAK is an aluminum electrolytic, snap-in terminal capacitor from Nichicon’s LKG series, engineered for audio equipment. It provides 8.2 mF (8200 µF) capacitance at a 63 V rating in a radial, can-style snap-in package optimized for high-fidelity audio power supply applications.

Key performance attributes include a 4.2 A ripple-current rating at 120 Hz, polarized construction, RoHS compliance, and a specified lifetime of 1000 hours at 85 °C. Note: this specific part is listed as End of Life.

Key Features

• Capacitance and Voltage — 8.2 mF (8200 µF) nominal capacitance with a 63 V rated voltage and ±20% tolerance for bulk energy storage in audio power rails.
• Audio-grade Series (Gold Tune, TYPE‑I) — Part code suffix "AK" corresponds to the LKG TYPE‑I (Gold Tune) grade, designed for high‑tone‑quality audio applications.
• High Ripple Current — Rated ripple current of 4.2 A at 120 Hz to support dynamic load demands in amplifier and power-supply circuits.
• Leakage and Loss Characteristics — Specified leakage current (product data) and a tangent of loss angle (tan δ) of 0.3; tan δ measurement conditions follow the LKG series standard (120 Hz, 20 °C).
• Robust Operating Range — Rated for operation from −40 °C to +85 °C with endurance defined as 1000 hours at 85 °C under rated voltage.
• Package & Mounting — Radial, snap-in can with φ35 × 45L dimensions; tray packing for handling and assembly.
• Regulatory — RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• High‑fidelity audio amplifiers — Bulk and smoothing capacitance for power-supply sections in high‑grade audio amplifiers and receivers.
• Audio power supplies — Energy reservoir and ripple suppression for audio equipment power rails where sustained current delivery and low loss are required.
• Professional audio equipment — Suitable for mixers, preamplifiers, and other audio systems that prioritize tone quality and stable supply filtering.

Unique Advantages

• High energy storage: 8.2 mF at 63 V provides significant bulk capacitance for sustained filtering and supply stability in audio designs.
• Designed for audio fidelity: LKG TYPE‑I (Gold Tune) grading signals the series’ focus on sonic performance for high‑tone‑quality applications.
• Handles dynamic loads: 4.2 A ripple-current rating at 120 Hz supports circuits with variable current draw typical of audio amplification stages.
• Wide temperature range with defined lifetime: −40 °C to +85 °C operating range and 1000 hours endurance at 85 °C address reliability under elevated thermal stress.
• Industry compliance: RoHS conformity supports regulatory requirements for modern electronic assemblies.
• Serviceable snap-in mounting: Radial snap-in can package enables secure chassis/PCB installation and simplified assembly handling.
