LKG1H123MESCAK

The LKG1H123MESCAK is a snap‑in terminal aluminum electrolytic capacitor from Nichicon’s LKG series, specified for audio equipment and high‑fidelity applications. This Type‑I (AK) "Gold Tune" grade part delivers 12,000 µF at 50 V in a φ35 × 40 mm can with snap‑in mounting and polarized construction.

Designed for audio use, the capacitor combines high capacitance and a low‑frequency ripple current capability with a 1,000‑hour endurance at 85°C, making it suitable for power filtering and energy reservoir roles in professional and high‑grade audio equipment. The part is RoHS‑compliant and is shipped in tray packing. Status: End Of Life.

Key Features

• Electrical Performance 12,000 µF rated capacitance at 50 V with ±20% tolerance (measured at 120 Hz, 20°C), providing substantial bulk energy storage for audio power rails.
• Audio‑Focused Loss Characteristics Specified tanδ (DF) of 0.3 measured at 20°C, 120 Hz, indicating controlled dissipation suitable for audio signal and power applications.
• Ripple Current Capability Low‑frequency ripple current rated at 4.35 A (120 Hz), supporting smoothing and filtering duties in audio power supplies.
• Leakage and Polarization Polarized design with measured leakage current of 2,320 µA; suitable for typical electrolytic capacitor use where polarized mounting is acceptable.
• Reliability & Endurance Rated for 1,000 hours at 85°C with defined endurance limits for capacitance change, tanδ, and leakage current when restored to 20°C.
• Package & Mounting Radial can, snap‑in terminal type (φ35 × 40 mm), designed for secure board mounting in audio chassis. Marking is printed in gold color on a black sleeve.
• Environmental Compliance RoHS compliant and delivered in tray packing for handling and assembly.

Typical Applications

• High‑fidelity audio amplifiers — Bulk energy storage and power rail smoothing to support dynamic audio demands.
• Professional audio equipment — Power supply filtering and reservoir functions in mixers, preamps, and processing racks.
• High‑grade consumer audio gear — Supporting stable DC rails in high‑performance receivers and integrated amplifiers.

Unique Advantages

• Large capacitance at 50 V: 12,000 µF of capacitance provides substantial energy buffering for audio power stages.
• Audio‑oriented grading (Type‑I / Gold Tune): Series classification indicates design focus on high‑tone quality audio applications.
• Measurable dissipation control: tanδ = 0.3 (20°C, 120 Hz) offers predictable loss behavior for designers tuning power and audio performance.
• Robust ripple handling: 4.35 A ripple current (120 Hz) supports heavy smoothing duties in low‑frequency power supplies.
• Endurance specification: 1,000 hours at 85°C provides a defined lifecycle metric for reliability planning.
• RoHS compliant and tray packed: Meets environmental directives and is packaged for production handling.
