LKG1E822MESCAK

The LKG1E822MESCAK is a snap‑in aluminum electrolytic capacitor from Nichicon’s LKG series, engineered for audio equipment applications. It combines high capacitance with a compact radial, snap‑in can package to support power filtering and reservoir duties in high‑grade audio systems.

Key electrical characteristics include 8,200 µF nominal capacitance at 25 V, a low‑frequency ripple current rating of 2.25 A (120 Hz), a specified tan δ of 0.3 (measured at 20°C, 120 Hz), and an operating temperature range of −40°C to +85°C, providing stable performance for audio power supplies and related circuitry.

Key Features

• Capacitance & Voltage — 8,200 µF nominal capacitance at a rated voltage of 25 V, with capacitance tolerance ±20% (measured at 120 Hz, 20°C).
• Audio‑Grade Construction — Part of the LKG series designed specifically for audio equipment; TYPE‑I (Gold Tune) configuration focused on tone quality and high‑fidelity applications.
• Low‑Frequency Ripple Handling — Rated low‑frequency ripple current of 2.25 A at 120 Hz to support smoothing and reservoir functions in audio power supplies.
• Loss Characteristics — Tangent of loss angle (tan δ) of 0.3 (measurement condition: 20°C, 120 Hz) for predictable AC loss behavior in filtering applications.
• Reliability & Endurance — Specified endurance of 1,000 hours at 85°C with performance limits defined for capacitance change, tan δ, and leakage current after endurance testing.
• Package & Mounting — Radial, snap‑in can (φ35 × 20 mm) for secure board mounting and compact placement; available in tray packing.
• Environmental Compliance — RoHS‑compliant construction.

Typical Applications

• High‑Fidelity Audio Amplifiers — Bulk reservoir and power‑supply smoothing to support stable supply rails and reduce low‑frequency ripple.
• Professional Audio Equipment — Power decoupling and energy storage in mixers, preamps, and rack‑mount systems where audio quality is prioritized.
• Consumer Hi‑Fi Systems — Filtering and supply stabilization in integrated receivers and high‑grade consumer audio electronics.

Unique Advantages

• High Capacitance in a Compact Can — 8,200 µF in a φ35 × 20 mm package offers significant energy storage while minimizing board footprint.
• Designed for Audio Performance — LKG series audio‑focused construction (TYPE‑I Gold Tune) targets tonal quality and fidelity needs in audio designs.
• Robust Ripple Capability — 2.25 A ripple rating at 120 Hz supports effective smoothing under typical audio power supply loads.
• Predictable Loss and Leakage — Specified tan δ and leakage current values (tan δ = 0.3; leakage current 1,350 µA) allow designers to model AC losses and standby drain reliably.
• Wide Operating Temperature Range — −40°C to +85°C rating supports deployment across typical audio equipment ambient conditions.
• Endurance‑Specified — 1,000‑hour endurance at 85°C provides a defined reliability baseline for system lifetime planning.
