LKG1E183MESBAK

The LKG1E183MESBAK is a snap‑in aluminum electrolytic capacitor offering 18,000 µF nominal capacitance at a 25 V rating. It is part of Nichicon’s LKG series, a family designed for high‑grade audio equipment where fidelity and robust power filtering are priorities.

Key attributes include high low‑frequency ripple capability, a wide operating temperature range of −40 °C to +85 °C, and a rated endurance of 1000 hours at 85 °C. Status: End Of Life — contact sales to confirm current availability.

Key Features

• High bulk capacitance: 18,000 µF (18 mF) provides substantial energy storage for power supply smoothing and reservoir applications in audio equipment.
• 25 V rated voltage: Suitable for common audio power rail voltages that require large bulk capacitance at moderate DC voltage.
• Low‑frequency ripple handling: 3.4 A ripple current at 120 Hz, enabling effective suppression of low‑frequency supply ripple and reduced heating under ripple stress.
• Leakage current specification: Specified leakage current of 2010 µA, enabling predictable bias current behavior for design and measurement.
• Loss tangent (tan δ): tan δ = 0.3 measured at 20 °C, 120 Hz, for assessing ESR‑related losses in audio power paths.
• Endurance and reliability: Specified life of 1000 hours at 85 °C with defined limits for capacitance change, tan δ, and leakage current after the test.
• Wide operating temperature: −40 °C to +85 °C to accommodate a range of environmental conditions encountered in professional audio equipment.
• Snap‑in radial can package: Rugged snap‑in mounting for secure board retention and serviceable replacement; supplied in tray packing for handling and assembly.
• RoHS compliant: Meets RoHS directive requirements as indicated for the LKG series.
• Compact footprint: Physical size approximately φ30 × 40 mm (D × L), useful for compact power supply layouts.

Typical Applications

• High‑fidelity audio amplifiers: Bulk reservoir and smoothing capacitor for amplifier power rails to support clean low‑frequency response.
• Studio and pro audio equipment: Power supply filtering in mixers, preamps, and outboard gear where sustained ripple handling and stability are required.
• Audio power supplies: DC rail decoupling and energy storage for local load transients in audio electronics.

Unique Advantages

• Large energy storage: 18,000 µF capacity reduces voltage sag during high demand, improving transient response in audio power stages.
• Designed for audio fidelity: LKG series design emphasis on high‑grade audio supports cleaner power delivery for sensitive audio circuits.
• High ripple tolerance: 3.4 A ripple current rating at 120 Hz lowers internal heating and extends service life in ripple‑intensive applications.
• Stable over temperature: Specified operation from −40 °C to +85 °C and 1000‑hour endurance at 85 °C provide predictable performance in varied environments.
• Serviceable snap‑in format: Radial snap‑in can simplifies replacement and mechanical retention on power supply PCBs.
• Regulatory compliance: RoHS compliance supports environmental and regulatory requirements for product design.
