LKX2G391MESC35

The LKX2G391MESC35 from Nichicon is a snap-in terminal, polarized aluminum electrolytic capacitor optimized for audio equipment and switching power supply applications. It combines a 390 µF capacitance with a 400 V rated voltage and a 105°C endurance class to address power-filtering and bulk-energy storage requirements in high-voltage electronic designs.

Designed as part of the LKX series, this radial can (snap-in) package delivers industry-relevant ripple performance and long-term stability, with RoHS compliance and tray packing suitable for production use.

Key Features

• Capacitance & Voltage — 390 µF rated capacitance at 400 V for high-voltage bulk storage and filtering.
• Snap-in Radial Can — Snap-in terminal mounting for secure board retention and straightforward assembly in power modules.
• Temperature and Endurance — Rated for operation from −25°C to +105°C with 2000 hours endurance at 105°C, supporting sustained high-temperature use.
• Low-Loss Performance — Specified tan δ of 0.15 at 20°C and 120 Hz for controlled dissipation factor in audio and power applications.
• High Ripple Capability — 1.55 A ripple current at 120 Hz (low frequency) and 2,216.5 mA at 50 kHz (high frequency) to handle both mains and switching ripple components.
• Leakage Current — Specified leakage current of 1,180 µA, suitable for high-voltage power circuits where controlled leakage is required.
• Physical Size & Marking — φ35 × 35L (3.5 × 3.5 cm) package with gold-on-black sleeve marking for clear identification.
• Environmental — RoHS compliant material selection for regulatory alignment in manufacturing.

Typical Applications

• Audio Equipment — Bulk decoupling and power supply smoothing in high-voltage audio amplifiers and related electronics to support stable power rails and reduce audible noise.
• Switching Power Supplies — Energy storage and output filtering for high-voltage SMPS designs where high ripple tolerance and 105°C endurance are required.
• General High-Voltage Power Electronics — DC link and bulk filter capacitor in industrial or commercial high-voltage power systems that require a polarized snap-in capacitor.

Unique Advantages

• High-Voltage Bulk Energy Storage: 390 µF at 400 V provides substantial capacitance for energy smoothing and transient support in high-voltage rails.
• Robust Thermal Endurance: 2000 hours at 105°C ensures predictable lifetime behavior under elevated operating temperatures.
• Dual-Frequency Ripple Handling: Rated ripple currents given for both 120 Hz and 50 kHz let designers address mains and switching components without guesswork.
• Audio-Oriented Materials: Part of the LKX series developed for audio equipment, leveraging selected materials and construction aimed at preserving sound quality in audio power stages.
• Production-Friendly Packaging: Tray packing and snap-in terminals simplify handling and assembly for mass production environments.
• Regulatory Compliance: RoHS conformity supports environmental compliance for commercial production.
