LKG1E183MESAAK

The LKG1E183MESAAK is an aluminum electrolytic, snap‑in terminal capacitor from Nichicon's LKG series, optimized for audio equipment. It delivers high bulk capacitance (18,000 µF) at a 25 V rating with a low-loss characteristic (tan δ = 0.3) and is intended for applications that require significant energy storage and ripple handling in audio designs.

Engineered for reliability in demanding environments, this component offers a rated operating range of −40°C to +85°C and an endurance specification of 1000 hours at 85°C, making it suitable for high‑fidelity audio systems where stable long‑term performance is required.

Key Features

• High Capacitance & Voltage: 18,000 µF nominal capacitance at 25 V provides substantial bulk energy storage for audio power rails and related circuits.
• Audio‑Oriented Design: Part of the LKG series designed "For Audio Use" and described for high‑grade audio equipment and high fidelity sound quality.
• Low Loss (tan δ): Specified tangent of loss angle of 0.3 (measurement frequency: 120 Hz at 20°C), indicating controlled dissipation for stable performance under AC excitation.
• Ripple Current Handling: Rated ripple current of 3.55 A at 120 Hz to support dynamic load conditions common in audio amplifier power supplies.
• Leakage Current Specification: Leakage current figures provided in the product data (expressed per manufacturer guidelines) to enable predictable bias behavior in circuits.
• Robust Endurance: Endurance rating of 1000 hours at 85°C with specified limits for capacitance change, tan δ and leakage current after test.
• Snap‑in Can Package: Radial, can‑style snap‑in mounting for secure mechanical retention and straightforward board assembly.
• RoHS Compliant: Compliant with RoHS directives as indicated in the product data.

Typical Applications

• High‑Fidelity Audio Amplifiers: Bulk filtering and energy storage on amplifier supply rails where large capacitance and controlled loss support stable audio performance.
• AV Receivers and Home Audio Systems: Power supply smoothing and reservoir capacitance in multi‑channel audio equipment requiring sustained current delivery.
• Studio and Professional Audio Gear: Use in mixer power supplies and other pro audio equipment where long endurance at elevated temperature and reliable ripple handling are important.

Unique Advantages

• Substantial Energy Storage: 18,000 µF at 25 V supplies a large reserve of charge to support transient loads and maintain stable rail voltages.
• Designed for Audio: Part of a series explicitly described as targeted for high‑grade audio equipment, aligning component selection with sound‑quality‑focused designs.
• High Ripple Capability: 3.55 A ripple current rating at 120 Hz allows the capacitor to handle AC stress typical of power supplies in audio systems.
• Durability at Elevated Temperatures: 1000‑hour endurance at 85°C provides predictable aging behavior and defined performance limits after stress testing.
• Secure Snap‑in Mounting: Radial snap‑in can package offers mechanical stability and repeatable assembly for production environments.
• Regulatory Compliance: RoHS compliance supports use in designs targeting restricted‑substance requirements.
