LKG1E123MESAAK

The LKG1E123MESAAK from Nichicon is an aluminum electrolytic, snap-in terminal capacitor engineered for high-grade audio equipment. It belongs to the LKG series and is configured as a TYPE-I (Gold Tune) unit, optimized for low-profile, high-tone quality through a new electrolyte formulation.

Designed for audio use and HD audio applications, this polarized radial can provides bulk energy storage and smoothing for power supplies and signal-chain circuits where fidelity and stable performance across temperature are important.

Key Features

• Audio-grade construction (TYPE-I – Gold Tune) Low-profile, high-tone-quality design using Nichicon’s new electrolyte formulation to prioritize high-fidelity sound in audio applications.
• Capacitance & voltage 12 mF capacitance rated at 25 V provides substantial bulk filtering capacity for audio power rails and decoupling.
• Mounting & package Snap-in terminal, radial can package for secure chassis or PCB mounting in audio equipment assemblies.
• Operating temperature & endurance Rated for −40°C to +85°C with an endurance specification of 1000 hours at 85°C under rated voltage; capacitance change remains within ±20% after the endurance test.
• Ripple current handling Rated ripple current of 2.75 A at 120 Hz to support power-supply smoothing in audio amplifiers and related circuits.
• Leakage and low-temperature characteristics Leakage current specification: after 5 minutes at 20°C, not more than 3√CV (µA) [C in µF, V in V]. Impedance stability: Z(−25°C)/Z(+20°C) ≤ 4 and Z(−40°C)/Z(+20°C) ≤ 12 (measured at 120 Hz).
• Polarized design Polarized electrolytic suitable for DC power filtering in audio equipment.
• RoHS compliant Conforms to RoHS directive (2011/65/EU, (EU)2015/863).
• Identification Marked with gold-color print on a black sleeve for quick visual identification.
• Compact footprint Physical dimensions: L: 4 cm × D: 2.5 cm, suitable for space-conscious audio chassis layouts.

Typical Applications

• High‑end audio amplifiers — Bulk filtering and power smoothing to help maintain stable DC rails for low-noise amplification and improved tonal quality.
• Professional audio equipment — Energy storage and decoupling in mixers, preamps, and studio gear where fidelity and reliable ripple handling are required.
• AV receivers and home theater — Supply decoupling and smoothing for multiple audio channels and digital/analog power domains.
• Audio power supplies — Bulk capacitance for regulated rails, benefiting transient response and low-frequency performance.

Unique Advantages

• Audio-first design: TYPE‑I (Gold Tune) grade and updated electrolyte emphasize tonal clarity and high-fidelity performance for audio applications.
• Substantial bulk capacitance at 25 V: 12 mF gives designers significant energy reserve for smoothing and transient support on audio power rails.
• Robust ripple capability: 2.75 A ripple rating at 120 Hz enables effective ripple suppression in audio power supplies and reduces audible noise sources.
• Wide temperature range with validated endurance: −40°C to +85°C operation and 1000 hours endurance at 85°C under rated voltage deliver predictable long-term behavior in deployed equipment.
• Measurable leakage and low-temperature performance: Clear leakage current limit and stated impedance ratios allow designers to model performance across temperature and comply with system requirements.
• RoHS compliance and clear marking: Lead-free directive conformance and gold-on-black sleeve marking simplify assembly and regulatory tracking.
