LNR2D333MSEN

The LNR2D333MSEN is a screw-terminal aluminum electrolytic capacitor designed for general-purpose power electronics requiring large bulk capacitance. It delivers 33,000 µF at a 200 V rating in a radial can with screw terminals, providing high ripple-current capability and long endurance for industrial and power-conversion applications.

Key value comes from its combination of high capacitance, strong low- and high-frequency ripple-current performance, and a 5,000-hour endurance at 85°C, making it suitable where robust energy storage and smoothing are required.

Key Features

• High Capacitance — 33,000 µF nominal capacitance (33 mF) provides substantial energy storage for bulk decoupling and DC-link applications.
• 200 V Rated Voltage — Rated for 200 V operation to support higher-voltage power systems within the LNR series range.
• High Ripple-Current Capability — Low-frequency ripple current of 19.5 A at 120 Hz and high-frequency ripple current of 23.4 A at 100 kHz to handle sustained AC ripple stress.
• Endurance and Temperature Range — Specified 5,000 hours lifetime at 85°C with operating temperature range of −25°C to 85°C, suitable for continuous high-temperature applications.
• Electrical Performance — Dissipation factor (tan δ) of 0.25 measured at 20°C, 120 Hz; leakage current specified at 5,000 µA.
• Robust Mechanical and Mounting — Radial can with screw terminals for secure, low-impedance connections; body dimensions φ90 × 170 mm (diameter × length) facilitate mounting with standard brackets for φ51 and larger sizes in the LNR series.
• Polarized Design & Tolerance — Polarized capacitor with capacitance tolerance of −20% to +20% at 120 Hz, 20°C.
• Mass Production and Packaging — Design is in mass production and supplied in cardboard packing; RoHS compliant.

Typical Applications

• Industrial Power Supplies — Bulk smoothing and energy buffering in high-voltage DC power supplies, leveraging 33,000 µF at 200 V and substantial ripple-current ratings.
• Power Conversion / Inverters — DC-link and filtering for converters and inverters where sustained ripple handling and long endurance at elevated temperature are required.
• Motor Drives — Energy storage and ripple suppression in motor-control power stages that operate at elevated currents and temperatures.
• Energy Storage and Buffering — Local energy reservoirs for systems requiring large capacitance and reliable discharge/recharge cycles over extended operating life.

Unique Advantages

• Large Energy Storage per Unit — 33,000 µF at 200 V reduces the number of parallel components needed for bulk capacitance, simplifying BOM and board layout.
• Designed for High Ripple Stress — Specified ripple currents at both low and high frequencies (19.5 A at 120 Hz, 23.4 A at 100 kHz) enable use in demanding power-electronics environments.
• Long Endurance at Elevated Temperature — 5,000 hours rating at 85°C supports reliable operation in continuous-duty industrial applications.
• Secure Screw-Terminal Connections — Robust, low-impedance screw terminals simplify heavy-current wiring and improve mechanical retention compared with solder-only mounts.
• Clear, Verifiable Electrical Specs — Tangent of loss angle, leakage current, and tolerance are specified to allow predictable design margining and verification.
• Compliance and Production Readiness — RoHS compliant and listed as mass production, facilitating predictable sourcing and regulatory alignment.
