LNT1H334MSEB

The LNT1H334MSEB is a screw‑terminal aluminum electrolytic capacitor from Nichicon's LNT series. It delivers a high-capacitance, polarized solution—330,000 µF at 50 V—designed for general-purpose energy storage and bulk smoothing in electronic power systems.

Built for demanding thermal and ripple environments, this radial can with screw terminals combines large capacitance, high ripple current capability, and a wide operating temperature range to support robust power designs.

Key Features

• High Capacitance — 330,000 µF (330 mF) nominal capacitance with ±20% tolerance, providing substantial bulk energy storage for power rails and decoupling.
• Rated Voltage — 50 V rated voltage suitable for medium-voltage power rails and storage applications.
• High Ripple Current — Low-frequency ripple current of 24.3 A (120 Hz) and high-frequency ripple current of 27.95 A (100 kHz), enabling sustained operation under heavy AC ripple loading.
• Endurance at Elevated Temperature — 2,000 hours rated life at +105°C when operated under rated ripple conditions, matching LNT series endurance for the 10–250 V range.
• Temperature Range — Rated for operation from −40°C to +105°C, supporting a wide range of environmental conditions.
• Low‑Frequency Loss — Tangent of loss angle (tan δ) specified at 0.75 (measured at 20°C, 120 Hz) for predictable AC performance.
• Leakage Current — Specified leakage current of 5,000 µA (after application of rated voltage), allowing designers to budget for standby and leakage losses.
• Screw Terminal Package — Radial can with screw terminals and M5 nominal bolt compatibility for secure electrical and mechanical connection; supplied in cardboard packing for bulk handling.
• RoHS Compliant — Meets RoHS requirements for environmental compliance.

Typical Applications

• General Power Filtering — Bulk smoothing and energy buffering on DC power rails where large capacitance and high ripple capability are required.
• Industrial Power Electronics — Energy storage and ripple management in industrial power supplies and converters operating up to +105°C.
• Backup and Hold‑Up Circuits — Local energy reservoir for ride-through and hold‑up time in systems needing substantial stored charge at 50 V.

Unique Advantages

• Large Energy Reservoir: 330,000 µF nominal capacitance delivers significant bulk storage to stabilize DC rails and reduce voltage sag.
• High Ripple Handling: Rated ripple currents of 24.3 A (120 Hz) and 27.95 A (100 kHz) enable reliable performance under heavy AC loading conditions.
• Thermal Endurance: 2,000‑hour life at +105°C under rated ripple conditions supports long-term operation in hot environments.
• Robust Mechanical Termination: Screw‑terminal radial can design with M5 nominal bolt compatibility simplifies secure electrical and mechanical mounting.
• Wide Operating Range: −40°C to +105°C operating temperature range accommodates diverse deployment environments.
• Regulatory Compliance: RoHS compliance helps meet environmental and regulatory requirements for assemblies.
