LNT2G392MSEH

The LNT2G392MSEH from Nichicon is a screw-terminal aluminum electrolytic capacitor rated 3.9 mF (3900 µF) at 400 V with a 105°C maximum operating temperature. Designed as a general-purpose power component, it delivers high ripple-current capability and long endurance for demanding high-voltage applications.

Packaged as a radial can with screw terminals, this capacitor combines robust electrical performance—including high-frequency and low-frequency ripple handling—with durable thermal and mechanical characteristics suitable for industrial power assemblies and other high-voltage systems.

Key Features

• Rated Capacitance & Voltage — 3.9 mF (3900 µF) nominal capacitance at 400 V DC, with capacitance tolerance ±20% (−20% to +20%).
• High Ripple Current — Designed for high ripple environments: 18.2 A at 120 Hz and 25.48 A at 100 kHz as specified for this part.
• Temperature & Lifetime — Operating temperature range −25°C to +105°C (for 160 to 500 V ratings) with a rated load life of 5,000 hours at 105°C.
• Screw Terminal Mounting — Radial can package with screw terminals for secure bolted connections and simplified wiring in power racks and assemblies.
• Package & Size — Can-style radial package; size dimension listed as L: 11 cm × D: 7.62 cm and a maximum seated height of 4.331 inches.
• Polarized Electrolytic — Polarized aluminum electrolytic construction for bulk energy storage and smoothing; ensure correct polarity in installation.
• Leakage Current Specification — Leakage current limited per Nichicon datasheet after 5 minutes’ application of rated voltage (see manufacturer documentation for formula and limits).
• RoHS Compliant — Conforms to RoHS requirements for restricted substances.

Typical Applications

• High-voltage power rails — Bulk capacitance and smoothing for 400 V DC systems where high ripple-current handling is required.
• Power electronics assemblies — Screw-terminal packaging and high ripple capability make it suitable for modular power supplies, inverters and industrial power modules.
• Energy storage and filtering — Large capacitance for charge buffering and filter applications in high-voltage power subsystems.

Unique Advantages

• High ripple tolerance: Specified ripple-current ratings at 120 Hz and 100 kHz provide quantifiable performance for designers addressing thermal rise and ESR-related heating.
• Long high-temperature life: 5,000-hour endurance at 105°C supports predictable long-term performance in elevated-temperature environments.
• Secure, serviceable connections: Screw terminal construction enables reliable bolted terminations and easier maintenance or replacement compared with soldered leads.
• Wide operating range: Rated for −25°C to +105°C (for 160–500 V ratings), allowing use across a broad set of high-voltage operating conditions.
• Clear specification set: Capacitance, tolerance, leakage, ripple, and lifetime are documented—helping engineers validate designs against quantified electrical and thermal limits.
• Compliance: RoHS conformity supports regulatory requirements for restricted substances in assemblies.
