LKG1V123MESCBK

The LKG1V123MESCBK is a snap-in aluminum electrolytic capacitor from Nichicon’s LKG series, specifically tailored for high-grade audio equipment where fidelity and stable power filtering are priorities. This part combines a 12,000 µF capacitance with a 35 V rating in a radial, snap-in can package optimized for audio power supply and signal-decoupling applications.

Per the LKG series type coding, the BK suffix identifies this unit as a TYPE-II center-grade device with electrode foil construction focused on sound quality and multiple-use applications. It is RoHS compliant and specified for 1,000 hours of endurance at 85°C.

Key Features

• High Capacitance: 12,000 µF provides substantial energy storage for power smoothing and low-frequency decoupling in audio power supplies.
• Rated Voltage: 35 V working voltage suitable for many amplifier and audio subsystem rails.
• Tolerance and Loss: ±20% capacitance tolerance and a specified tanδ of 0.3 (measured at 120 Hz, 20°C) for predictable AC characteristics in audio circuits.
• Leakage Current: Specified leakage current of 1,940 µA after application of rated voltage, enabling design considerations for bias and standby currents.
• Ripple Current Capability: 4.1 A at 120 Hz, supporting power-stage ripple handling in audio amplifier supplies.
• Thermal and Endurance Profile: Rated operating temperature range −40°C to +85°C with 1,000 hours endurance at 85°C (meetings restored-spec criteria after test).
• Package and Mounting: Radial, snap-in can (snap-in terminal) for secure chassis or PCB assembly in power supply modules.
• RoHS Compliance: Compliant to RoHS directives (2011/65/EU,(EU)2015/863).
• Physical Footprint: Body dimensions L: 4.5 × D: 3.5 cm for compact integration into audio assemblies.

Typical Applications

• High-Grade Audio Amplifiers: Energy storage and power-supply smoothing to support clean, stable rails for power stages and output stages.
• Preamplifiers and DAC Power Modules: Bulk decoupling and low-frequency filtering where capacitor characteristics affect audible performance.
• Active Crossovers and Signal Processing Units: Supply stabilization for analog and mixed-signal audio circuitry to maintain consistent performance under varying load.

Unique Advantages

• Audio-Oriented Design: TYPE-II center-grade electrode foil construction targeted at improved sound quality and multi-use audio applications.
• Strong Energy Reserve: 12,000 µF capacitance provides significant bulk storage to reduce supply sag and support transient current demands in audio systems.
• Robust Ripple Handling: 4.1 A ripple current rating at 120 Hz helps manage power-stage ripple and reduces heating in demanding audio power supplies.
• Engineered Endurance: 1,000 hours at 85°C endurance rating supports reliable operation in thermally stressed audio enclosures.
• Practical Mounting: Snap-in radial can package enables reliable mechanical retention for power modules and chassis-mounted audio equipment.
• Regulatory Compliance: RoHS conformity for use in designs requiring restricted-substance compliance.
