LNR1H333MSE

The LNR1H333MSE is a Nichicon LNR series aluminum electrolytic capacitor in a screw-terminal radial can package. It provides 33,000 µF capacitance at a 50 V rating in a polarized design suited for bulk energy storage and high-ripple applications.

Designed for general-purpose power applications, this unit offers robust ripple handling and long-term endurance up to 5,000 hours at 85°C, making it appropriate for industrial and power-electronics systems that require secure screw-terminal connections and large-capacity smoothing.

Key Features

• High Capacitance — 33,000 µF (33 mF) nominal capacitance with ±20% tolerance at 120 Hz, providing substantial bulk energy storage for power smoothing and hold-up.
• Rated Voltage — 50 V DC rated voltage suitable for a wide range of mid-voltage power rails and power-supply applications.
• Screw Terminal Mounting — Radial can with screw terminals (φ51 body diameter); designed for secure, low-resistance connections using standard bolt mounting (φ51 nominal bolt: M5 as specified in the series documentation).
• Temperature Range and Endurance — Operating range −40°C to +85°C with endurance specification of 5,000 hours at 85°C under DC bias plus rated ripple current.
• Ripple Current Capability — Ripple current ratings of 7 A at 120 Hz and 8.05 A at 100 kHz, supporting high-demand AC ripple environments.
• Compact, Defined Size — Body dimensions approximately φ51 × 70 mm (L: 7.0 cm × D: 5.1 cm), enabling integration where high capacitance must fit into a controlled footprint.
• Reliability Metrics — Leakage current defined per datasheet as not more than 3√CV (µA) or 5 mA after 5 minutes at 20°C; shelf-life and endurance specifications included in the LNR series documentation.
• Regulatory Compliance — RoHS-compliant construction.

Typical Applications

• Power Supply Bulk Filtering — Large-capacitance bulk reservoir for smoothing DC outputs and improving hold-up time in converters and linear supplies.
• Industrial Power Electronics — Energy buffering and ripple absorption in motor drives, inverters, and welders where high ripple currents and secure screw connections are required.
• UPS and Energy Storage Subsystems — Bulk energy storage for short-term power delivery and voltage stabilization at up to 50 V system rails.
• High-Ripple Commercial Equipment — Systems with substantial AC ripple at both low and high frequencies, taking advantage of the 120 Hz and 100 kHz ripple current ratings.

Unique Advantages

• Large Stored Energy in a Single Device: 33,000 µF nominal capacitance reduces the number of parallel capacitors needed for bulk storage and smoothing.
• Screw-Terminal Security: Robust screw terminals and standard bolt sizing (φ51 / M5) deliver low-resistance, vibration-resistant connections for industrial installations.
• Designed for Continuous Duty: Endurance rating of 5,000 hours at 85°C under DC bias and rated ripple current provides predictable lifetime performance in elevated-temperature environments.
• Broad Ripple Handling: Rated ripple currents at both 120 Hz and 100 kHz accommodate a range of switching and line-frequency stress conditions.
• Clear Thermal and Electrical Limits: Specified operating temperature range and leakage-current limits allow straightforward thermal and reliability planning in designs.
• RoHS Compliance: Meets RoHS requirements for environmentally conscious designs.
