LKX2G820MESY30

The LKX2G820MESY30 is a snap-in terminal aluminum electrolytic capacitor designed for audio equipment and switching power supplies. It delivers 82 µF capacitance at a 400 V rating in a radial, can-type snap-in package optimized for reliable board mounting.

Built from selected materials for superior acoustic sound and rated for operation up to 105°C, this RoHS-compliant part targets general-purpose power filtering and audio applications that require high-temperature endurance and steady ripple performance.

Key Features

• Capacitance & Voltage — 82 µF nominal capacitance with a 400 V rated voltage and ±20% tolerance, suitable for high-voltage power filtering tasks.
• High-temperature Endurance — Designed for operation from −25°C to +105°C with a rated lifetime of 2000 hours at 105°C when subjected to DC bias plus rated ripple current.
• Snap-in Package — Radial, can-style snap-in mounting for secure mechanical retention and easy insertion into power supply boards.
• Ripple Current Capability — Specified ripple current handling of 640 mA at 120 Hz and 915.2 mA at 50 kHz to support switching supply and high-frequency applications.
• Polarized Design — Polarized electrolytic construction for conventional DC filtering and energy storage in power rails.
• Acoustic Optimization — Manufactured from selected materials to achieve superior acoustic sound characteristics for audio-focused designs.
• RoHS Compliance — Compliant with RoHS directives (2011/65/EU, (EU)2015/863).

Typical Applications

• Audio Equipment — Power supply smoothing and decoupling in audio amplifiers and other sound-sensitive electronics, leveraging materials selected for improved acoustic performance.
• Switching Power Supplies — Bulk and output filtering where a 400 V rating and strong ripple current capability are required.
• General Purpose Power Filtering — DC bus and rail stabilization in industrial and commercial power circuits that need a polarized, high-voltage electrolytic solution.

Unique Advantages

• High-voltage handling: 400 V rated voltage supports higher-voltage rails without uprating multiple lower-voltage components.
• Designed for elevated temperatures: 105°C operating rating with a 2000-hour endurance at 105°C provides predictable performance in thermally demanding designs.
• Frequency-capable ripple performance: Specified ripple currents of 640 mA (120 Hz) and 915.2 mA (50 kHz) support both low- and high-frequency switching environments.
• Acoustic-focused materials: Selected materials intended to improve sound quality make this capacitor well suited for audio-centric power stages.
• Secure snap-in mounting: Radial snap-in can package provides reliable mechanical retention for power board assemblies.
• Regulatory compliance: RoHS conformity for use in regions requiring restricted substance compliance.
