LNK2G392MSEHBN

The LNK2G392MSEHBN is a screw-terminal, aluminum electrolytic capacitor in Nichicon’s LNK series designed for general-purpose power applications. It provides 3.9 mF (3900 µF) capacitance at a 400 V rating in a radial can with screw terminals, delivering high ripple-current capability and long endurance for demanding power circuits.

Targeted at engineers and procurement for industrial and general-purpose power designs, this part combines high-voltage bulk capacitance with robust ripple handling, RoHS compliance, and mass-production availability.

Key Features

• Capacitance & Voltage — 3.9 mF (3900 µF) nominal capacitance rated at 400 V with ±20% tolerance at 20°C, 120 Hz.
• Screw Terminal Package — Radial, can-style package with screw terminals and M5 nominal bolt size suitable for secure electrical and mechanical connections.
• High Ripple Current Capability — Designed for heavy ripple loading: 13,000 mA (13 A) at 120 Hz and 18,200 mA (18.2 A) at 10 kHz to support filtering and smoothing in power stages.
• Electrical Losses & Leakage — Specified tangent of loss angle (tan δ) of 0.2 at 20°C, 120 Hz, and a measured leakage current of 3,740 µA for predictable performance under DC bias.
• Temperature Range & Endurance — Rated for operation from −25°C to +85°C with a rated load-life endurance of 5,000 hours at 85°C under specified ripple conditions.
• Form Factor & Dimensions — Compact LNK-series smaller-sized form: φ76.2 × 95L (L: 9.5 × D: 7.62 cm), packaged in cardboard and available in mass production.
• Regulatory — RoHS compliant.
• Polarized Construction — Polarized electrolytic design for DC energy storage and smoothing.

Typical Applications

• General-purpose power supplies — Bulk energy storage and smoothing in 400 V-class DC supply rails where high ripple handling is required.
• Power conversion and inverters — Supports filtering and DC-link requirements in general-purpose converters that operate within the part’s voltage and temperature limits.
• Industrial power modules — Provides durable capacitance and ripple endurance for long-life industrial power equipment operating up to 85°C.

Unique Advantages

• High-voltage bulk capacitance: 3900 µF at 400 V provides significant energy storage in a single component, simplifying BOM for 400 V designs.
• Robust ripple performance: Separate low- and high-frequency ripple ratings (13 A at 120 Hz, 18.2 A at 10 kHz) make behavior predictable across switching and line-frequency conditions.
• Endurance under load: 5000 hours life at 85°C with rated ripple current demonstrates long-term stability for continuous-duty applications.
• Secure screw-terminal mounting: M5 screw-terminal configuration supports reliable electrical connection and mechanical retention in rack or chassis installations.
• Measured electrical characteristics: Specified tan δ (0.2 at 20°C/120 Hz) and defined leakage current (3,740 µA) aid impedance and loss budgeting in power-stage designs.
• Compliance and availability: RoHS compliance and mass-production status reduce procurement and compliance risk.
