LKG1J821MESACK

The LKG1J821MESACK is an aluminum electrolytic capacitor from Nichicon’s LKG series, engineered specifically for high-grade audio equipment. This unit is a TYPE-I (Gold Tune) snap-in radial can designed to prioritize high-fidelity sound quality in audio applications.

Its key value lies in audio-focused electrical characteristics—820 µF capacitance at 63 V, controlled loss (tan δ), and rated ripple current—combined with a compact, low-profile snap-in package and RoHS compliance for straightforward integration into professional audio designs.

Key Features

• Audio-Grade TYPE-I (Gold Tune) Low-profile, high-tone-quality grade tailored for high-grade and HD audio equipment.
• Capacitance & Voltage 820 µF nominal capacitance with a 63 V rated voltage and ±20% tolerance (measured at 120 Hz, 20 °C).
• Controlled Loss Specified tangent of loss angle (tan δ) of 0.22 (measurement reference: 120 Hz, 20 °C), supporting stable audio performance.
• Ripple Handling Ripple current rated at 1.85 A (120 Hz), enabling reliable smoothing and decoupling in audio power circuits.
• Package & Mounting Radial can, snap-in terminal type for secure board mounting; compact dimensions approximately 2.5 × 2.5 cm.
• Operating Range & Endurance Operating temperature −40 °C to +85 °C with a rated lifetime of 1000 hours at 85 °C; endurance criteria include capacitance change within ±20% after the specified test.
• Leakage Current Specification Leakage current defined per datasheet: after 5 minutes at rated voltage and 20 °C, leakage ≤ 3√(C·V) μA (C in μF, V in V).
• Environmental Compliance RoHS compliant, marked with gold-colored lettering on a black sleeve consistent with the LKG series.

Typical Applications

• High‑Grade Audio Equipment Designed for use in amplifiers, preamplifiers and other professional audio gear where tone quality and low-loss performance are priorities.
• HD Audio Systems Used where improved fidelity and stable filtering are required for high-resolution playback and signal paths.
• Power Supply Filtering in Audio Electronics Suitable for smoothing and decoupling tasks in audio power rails, benefiting from the part’s ripple rating and endurance.

Unique Advantages

• Audio-focused formulation: TYPE‑I Gold Tune grade tuned for tone quality, supporting high-fidelity sound reproduction.
• Compact, serviceable package: Snap-in radial can construction provides a stable mounting option that fits space-constrained audio assemblies.
• Verified endurance: Rated for 1000 hours at 85 °C with specified post-test limits on capacitance, tan δ and leakage current for predictable long-term behavior.
• Clear electrical specifications: 820 µF / 63 V with ±20% tolerance and defined tan δ and ripple current values to simplify design trade-offs and BOM selection.
• Regulatory clarity: RoHS compliance for environmental requirements in commercial audio products.
