LNT1H334MSE

The LNT1H334MSE from Nichicon is a screw-terminal aluminum electrolytic capacitor in the LNT series designed for general-purpose power applications. It delivers high bulk capacitance (330 mF) at a rated voltage of 50 V, a wide operating temperature range, and robust ripple-current handling for demanding power systems.

Built for reliability in elevated-temperature environments, this radial can with screw terminals supports system-level smoothing, bulk energy storage and DC link applications where secure electrical and mechanical connections are required.

Key Features

• High Capacitance & Voltage: 330 mF capacitance rated at 50 V provides substantial bulk energy storage for filtering and smoothing tasks.
• Wide Operating Temperature: Rated from –40 °C to +105 °C, enabling operation across common industrial temperature ranges.
• Endurance at Elevated Temperature: Load life specified as 2,000 hours at +105 °C under rated ripple conditions, supporting sustained high-temperature operation.
• High Ripple Current Capability: Rated ripple current of 24.3 A at 120 Hz and 27.95 A at 100 kHz to handle substantial AC components on DC rails.
• Screw Terminal Mounting: Radial can package with screw terminals provides strong, low-resistance connections for high-current systems and easy integration into power assemblies.
• Polarized Electrolytic: Polarized design with ±20% capacitance tolerance suitable for conventional DC bulk and smoothing roles.
• RoHS Compliant: Meets RoHS directive requirements (2011/65/EU, (EU)2015/863) for environmental compliance.

Typical Applications

• General Purpose Power Filtering: Bulk smoothing and decoupling in power supplies and converters where high capacitance and rated ripple current are required.
• DC Link and Energy Storage: Local energy reservoir for DC link circuits and hold-up functionality in industrial power systems using screw-terminal connections for secure mounting.
• High-Temperature Environments: Power subsystems that must operate reliably up to +105 °C and require long-term capacitance stability.

Unique Advantages

• Substantial Bulk Capacitance: 330 mF at 50 V reduces the number of capacitors required for energy storage, simplifying BOM and layout.
• Robust Ripple Handling: High ripple-current ratings at both 120 Hz and 100 kHz help manage AC stress and reduce heating in demanding power applications.
• Screw-Terminal Reliability: Mechanical and electrical security of screw terminals supports high-current connections and straightforward assembly in rugged systems.
• High-Temperature Endurance: Specified 2,000-hour load life at +105 °C provides predictable performance in elevated-temperature installations.
• Industry-Friendly Form Factor: Radial can with screw terminals integrates into standard power assemblies and mounting brackets for larger-signal designs.
• Regulatory Compliance: RoHS compliance supports environmentally conscious designs and procurement requirements.
