LNT1H334MSEN

The LNT1H334MSEN is a screw-terminal, radial can aluminum electrolytic capacitor in Nichicon's LNT series designed for general-purpose power applications. It provides very large bulk capacitance (330,000 µF) at a 50 V rating with a φ90 × 220 mm package and screw-terminal connections for robust electrical and mechanical installation.

Engineered for high ripple environments and elevated operating temperatures, this part offers rated ripple current capability, a wide operating temperature range of −40°C to +105°C, and a 2,000 hour endurance at 105°C, making it suitable where large energy storage and reliable performance are required.

Key Features

• High Capacitance — 330,000 µF bulk capacitance for substantial energy storage and smoothing in power systems.
• 50 V Rated Voltage — Designed for applications requiring up to 50 V DC working voltage.
• Screw Terminal Radial Can — Robust screw-terminal mounting (φ90 size uses M5 nominal bolt) for secure, low-resistance connections suitable for high-current paths.
• Ripple Current Capability — Low-frequency ripple current 24.3 A at 120 Hz and high-frequency ripple current 27.95 A at 100 kHz, enabling effective handling of AC ripple across a broad frequency range.
• Temperature and Endurance — Operating range −40°C to +105°C with rated life of 2,000 hours at 105°C under rated ripple and bias conditions.
• Electrical Characteristics — Capacitance tolerance ±20%; tangent of loss angle (tan δ) 0.75 (measured at 20°C, 120 Hz); specified leakage current 5,000 µA.
• RoHS Compliant & Production Ready — Conforms to RoHS and is in mass production; packaged in cardboard for handling and shipping.

Typical Applications

• Power Supply Bulk Filtering — Large capacitance and high ripple current ratings support smoothing and bulk energy storage in DC power supplies and rectifier stages.
• DC Link and Power Conversion — Screw-terminal construction and high ripple capability suit use in DC link networks for inverters, converters, and motor drive systems.
• Energy Storage for Backup Systems — High capacitance with robust leakage and endurance characteristics makes it applicable where short-term energy buffering or ride-through capability is required.

Unique Advantages

• Exceptional Bulk Capacity: 330,000 µF provides significant stored charge per unit for demanding smoothing and buffering tasks, reducing the need for multiple parallel components.
• Heavy-Duty Electrical Connections: Screw terminals (M5 for φ90) enable secure, low-impedance connections for high-current circuits and simplified field wiring.
• Wide Frequency Ripple Performance: Specified ripple current at both 120 Hz and 100 kHz addresses AC ripple across converter and switching frequencies, supporting versatile power designs.
• High-Temperature Endurance: Rated life of 2,000 hours at 105°C under rated ripple/bias conditions supports reliable operation in elevated-temperature environments.
• Clear Electrical Limits: Published tan δ, leakage current, and capacitance tolerance allow predictable design margining and verification in system-level analysis.
• Regulatory Compliance: RoHS compliance supports deployment in regions and products that require restricted-substance adherence.
