LKG1E821MESZCK

The LKG1E821MESZCK is a snap‑in terminal aluminum electrolytic capacitor from Nichicon’s LKG series, specified at 820 µF and 25 V for audio applications. It is designed for high‑grade audio equipment with emphasis on tone quality and high fidelity sound.

Note: this part is listed as End of Life / Discontinued. Request a quote for current availability or inquire about recommended alternatives in the LKG series.

Key Features

• Electrical Performance — Rated capacitance 820 µF at 25 V with a specified tangent of loss angle (tan δ) of 0.22 (measurement conditions referenced at 120 Hz, 20 °C in the series datasheet).
• Package & Mounting — Snap‑in terminal, radial can package (φ22 × 20L) suitable for snap‑in mounting in audio chassis and assemblies.
• Operating Range & Endurance — Operates from −40 °C to +85 °C; endurance defined as 1000 hours at 85 °C with capacitance change within ±20% of initial value after test.
• Ripple Capability — Rated ripple current: 750 mA at 120 Hz (low frequency specification).
• Polarized Electrolytic — Polar type capacitor intended for DC applications where polarity is observed.
• Leakage Current Spec — Leakage current limit per series definition: after 5 minutes’ application of rated voltage at 20 °C, leakage current not more than 3√(C·V) μA [C: μF, V: V].
• Marking & Compliance — Printed with gold color lettering on a black sleeve; RoHS compliant per the series documentation.

Typical Applications

• High‑grade audio equipment — For designers specifying components that support tone quality and fidelity in consumer and professional audio systems.
• HD audio systems — Targeted at systems where the LKG series’ stated priority on high tone quality is important to overall sound performance.
• Professional audio gear — Suitable where snap‑in packaging and defined endurance at elevated temperatures are required for rack or chassis installations.

Unique Advantages

• Audio‑focused design: The LKG series is designed specifically for high‑grade audio use, emphasizing high fidelity and tone quality.
• Low loss characteristic: A tan δ of 0.22 supports lower dissipation in audio signal and power circuits, consistent with the series’ audio priorities.
• Robust thermal endurance: Specified endurance of 1000 hours at 85 °C provides defined long‑term behavior under elevated operating conditions.
• Defined leakage limits: Leakage current limited by the 3√(C·V) rule after voltage application, enabling predictable DC performance.
• Snap‑in form factor: Radial snap‑in can (φ22 × 20L) for secure mechanical mounting in audio chassis and assemblies.
• Regulatory compliance: RoHS compliance provides assurance for environmental regulatory requirements.
