LNR1C334MSE

The LNR1C334MSE is a screw-terminal aluminum electrolytic capacitor from Nichicon’s LNR series, providing very high capacitance in a robust radial can with screw terminals. It is designed for general-purpose applications that require large bulk capacitance, substantial ripple-current handling and long endurance under elevated temperature.

Key design attributes include 330,000 µF capacitance at 16 V, endurance specified for 5,000 hours at 85°C, and high ripple-current capability at both low and high frequencies—making it suitable where energy storage and repeated current pulses are present.

Key Features

• High Capacitance: 330,000 µF (330 mF) nominal capacitance with tolerance of −20% to +20% at 120 Hz, 20°C.
• Rated Voltage: 16 V working voltage suitable for many DC bus and bulk-storage applications.
• High Ripple-Current Capability: 25.1 A at 120 Hz (low frequency) and 28.86 A at 100 kHz (high frequency) to support repeated current pulses and smoothing tasks.
• Endurance and Temperature Range: Rated lifetime of 5,000 hours at 85°C and operating temperature range −40°C to +85°C.
• Low-Frequency Loss (tan δ): tanδ = 0.75 measured at 20°C, 120 Hz for loss characterization.
• Screw Terminal Radial Can: φ63.5 × 120 mm package with screw-terminal mounting and M5 nominal terminal bolt for secure electrical and mechanical connection.
• Leakage Current Specified: Leakage current listed as 5,000 µA after application of rated voltage.
• RoHS Compliant and Production-Ready: RoHS status compliant and product is in mass production.

Typical Applications

• Industrial Power Supplies — Bulk energy storage and DC bus filtering where high capacitance and substantial ripple-current capability are required.
• Power Conversion Systems — Use in general-purpose converters and inverters that demand long-endurance capacitors with secure screw-terminal connections.
• Backup Power and Hold-Up — Energy hold-up and smoothing roles in systems needing large stored charge and stable performance up to 85°C.

Unique Advantages

• Large Stored Energy per Component: 330,000 µF nominal capacitance reduces the number of parallel parts required for high-capacitance designs.
• High Ripple Handling Across Frequencies: Rated ripple currents at 120 Hz and 100 kHz support both mains-frequency smoothing and higher-frequency switching environments.
• Long Endurance at Elevated Temperature: 5,000-hour life at 85°C provides predictable aging and useful lifetime for demanding installations.
• Secure Screw-Terminal Interface: Radial can with screw terminals and M5 nominal bolt diameter ensures robust electrical connection and easy field wiring or replacement.
• Clear Electrical Loss Characterization: Specified tanδ (0.75 at 20°C, 120 Hz) and defined leakage current allow straightforward thermal and loss budgeting in designs.
• Production Availability and Compliance: Mass-production status and RoHS compliance simplify procurement and regulatory integration.
