The LKG1E183MESCAK is an aluminum electrolytic, snap‑in terminal capacitor from Nichicon’s LKG series, designed specifically for high‑grade audio equipment. It delivers large bulk capacitance in a radial can snap‑in package suitable for power smoothing and energy storage in HD audio systems.

Key electrical and mechanical characteristics include a rated capacitance of 18,000 µF (18 mF), rated voltage of 25 V, polarization, a -40 °C to +85 °C operating range, and RoHS compliance. The part is produced as TYPE‑I (Gold Tune) — a low‑profile, high tone quality grade in the LKG family.

Key Features

• High Capacitance: 18,000 µF (18 mF) provides substantial energy reserve for audio power rails and bulk filtering.
• Rated Voltage: 25 V rated voltage suitable for a variety of low‑voltage audio amplifier and preamplifier power supplies.
• Snap‑in Radial Can Package: Snap‑in terminal mounting for secure mechanical retention and straightforward PCB assembly in high‑current audio applications.
• Audio‑focused Grade: TYPE‑I (Gold Tune) designation from the LKG series — specified for low‑profile, high tone quality in high‑grade audio equipment.
• Operating Environment: Specified operating temperature range of -40 °C to +85 °C with an endurance rating of 1000 hours at 85 °C.
• Ripple Handling: Rated ripple current of 3.5 A at 120 Hz, enabling AC current handling appropriate for power supply filtering in audio circuits.
• Tolerance & Polarization: Capacitance tolerance ±20% and polarized construction — suitable for DC power rail applications where polarity is defined.
• Leakage Current Specification: Leakage current limited to not more than 3√(C·V) µA after 5 minutes at 20 °C, per the LKG series specification.
• Compact Footprint: Physical dimensions approximately Diameter 35 mm × Length 30 mm (L: 3 cm × D: 3.5 cm), enabling integration into compact audio power modules.
• Regulatory: Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• High‑Fidelity Audio Amplifiers: Bulk energy storage and smoothing for power rails in stereo and multichannel amplifiers to support stable low‑noise operation.
• HD Audio Equipment: Capacitive reservoir for digital‑analog front ends and power supplies in high‑grade audio systems where tone quality is a priority.
• Studio and Professional Audio Gear: Power filtering and decoupling in mixers, preamps, and processing units that require large capacitance and reliable ripple handling.
• Consumer Hi‑Fi Components: Power supply stabilization in integrated amplifiers, receivers, and other high‑end consumer audio electronics.

Unique Advantages

• Designed for Audio Quality: TYPE‑I (Gold Tune) grade emphasizes low‑profile, high tone quality for systems prioritizing fidelity.
• Large Energy Reserve: 18,000 µF capacity reduces voltage sag and supports dynamic audio peaks by providing substantial stored charge near the load.
• Robust Ripple Capability: 3.5 A ripple current rating at 120 Hz supports effective AC current handling for power supply filtering tasks.
• Wide Temperature Range and Endurance: Rated for -40 °C to +85 °C with 1000 hours endurance at 85 °C, enabling consistent performance in typical audio equipment environments.
• Secure Snap‑in Mounting: Radial snap‑in package provides reliable mechanical retention for chassis and PCB assemblies in professional equipment.
• Regulatory Compliance: RoHS compliance ensures suitability for designs requiring restricted‑substance conformance.
