LNT1V334MSEB

The LNT1V334MSEB from Nichicon is a screw-terminal aluminum electrolytic capacitor offering 330,000 µF capacitance at 35 V in a robust radial can package. Designed for high-energy storage and bulk filtering, it targets industrial and power-electronics applications that require large capacitance, high ripple handling, and long-term endurance at elevated temperatures.

This screw-terminal design (φ90 × 170 mm) provides secure mechanical and electrical connections for high-current systems, while RoHS compliance and cardboard packing support standard procurement and assembly practices.

Key Features

• High Capacitance: 330,000 µF (330 mF) provides substantial bulk energy storage for smoothing, hold-up and decoupling in power systems.
• Rated Voltage: 35 V rated voltage suitable for mid-voltage DC bus and power-supply applications.
• Screw Terminal Mounting: Radial can with screw terminals (φ90 can, nominal bolt M5) for secure, low-resistance connections in high-current assemblies.
• High Ripple Capability: Low-frequency ripple current 21.3 A (120 Hz) and high-frequency ripple current 24.5 A (100 kHz) to handle significant AC stress under operating conditions.
• Endurance at Elevated Temperature: Rated life of 2,000 hours at +105°C under DC bias plus rated ripple current (per series load-life specification for 10–250 V range).
• Leakage and Loss Characteristics: Leakage current specified at 5,000 µA and tan δ (DF) of 1 measured at 20°C, 120 Hz.
• Operating Range and Compliance: Operating temperature −40°C to +105°C and RoHS compliant.
• Packaging: Supplied in cardboard packing for bulk handling and protection during transport.

Typical Applications

• Power Supply Bulk Filtering: Large capacitance and high ripple current capability make it suitable for DC bus smoothing and hold-up in industrial and commercial power supplies.
• Inverter and Motor Drives: Robust screw-terminal connections and high ripple handling support energy buffering and ripple suppression in motor drive and inverter assemblies.
• Energy Storage and UPS Systems: High capacitance provides extended hold-up and energy reservoir capability for uninterruptible power supplies and energy storage modules.

Unique Advantages

• Large Energy Density: 330,000 µF capacitance delivers substantial bulk storage in a single component, reducing the number of parallel capacitors required.
• Secure High-Current Termination: Screw-terminal construction with M5 bolt nominal threading ensures reliable mechanical and electrical connection for high-current paths.
• Designed for Elevated Temperatures: Rated for operation to +105°C with a specified 2,000-hour endurance under rated ripple and DC bias, enabling use in hot operating environments.
• Wide Ripple Bandwidth: Specified ripple performance at both 120 Hz and 100 kHz supports a range of power-conversion topologies and switching frequencies.
• Standards-Friendly Packaging: Cardboard packing simplifies handling and storage while supporting bulk procurement workflows.
