LNT1E334MSEN

The LNT1E334MSEN from Nichicon's LNT series is a screw-terminal aluminum electrolytic capacitor providing 330000 µF (330 mF) capacitance at a 25 V rating in a φ90 × 140 mm can. It is a polarized, radial can device designed for general-purpose power applications that require large bulk capacitance and rugged screw-terminal connections.

Designed to operate from −40 °C to 105 °C with an endurance rating of 2000 hours at 105 °C, this part delivers substantial low- and high-frequency ripple current capability (20.8 A at 120 Hz and 23.92 A at 100 kHz), making it suitable where high ripple handling and energy reserve are required. Packaging is supplied in cardboard packing and the product is in mass production.

Key Features

• High Capacitance & Voltage: 330000 µF nominal capacitance at a 25 V rating provides large energy storage for bulk filtering and hold-up applications.
• Screw Terminal Package: Radial can with screw terminals simplifies secure, low-resistance connections for high-current systems; nominal bolt size and terminal pitch follow LNT series dimensions for φ90 devices.
• High Ripple Current Handling: Rated ripple currents of 20.8 A (120 Hz) and 23.92 A (100 kHz) support heavy AC ripple in power supplies and converters.
• Robust Thermal Performance: Operating range −40 °C to +105 °C with a specified endurance of 2000 hours at 105 °C under rated ripple conditions.
• Electrical Characteristics: Capacitance tolerance −20% to +20%; tan δ (DF) of 1.5 measured at 20 °C, 120 Hz; leakage current rated at 5000 µA.
• Compliance & Packaging: RoHS‑compliant and supplied in cardboard packing for safe handling and shipment; product status is mass production.

Typical Applications

• Power Supply Bulk Filtering: Large capacitance and high ripple current make it well suited for smoothing and energy storage on low-voltage DC rails.
• DC Link / Power Conversion: Provides energy reserve and ripple suppression in DC–DC converters, inverters, and motor drive intermediate circuits at 25 V systems.
• Backup & Hold-Up Circuits: Stores charge for short-term hold-up or ride-through in uninterruptible power and backup-bias applications.
• Industrial Power Equipment: Rugged screw terminals and wide operating temperature range support installation in heavy-duty industrial power electronics and control systems.

Unique Advantages

• Massive Energy Storage: 330000 µF provides substantial bulk capacitance in a single component, reducing the number of parallel capacitors required.
• Designed for High Ripple Loads: High rated ripple currents (20.8 A / 23.92 A) enable reliable operation under significant AC stress without frequent replacements.
• Temperature and Endurance Specified: Specified for operation to 105 °C with a defined 2000-hour endurance at that temperature, allowing designers to plan for long-term performance.
• Secure Mechanical Termination: Screw terminals offer low-resistance, vibration-resistant connections ideal for high-current and industrial environments.
• RoHS Compliance: Meets RoHS requirements for restricted substances, supporting regulatory and environmental goals.
• Ready for Production: Product is in mass production and shipped in cardboard packing for efficient handling and inventory integration.
