LNR1K333MSEN

The LNR1K333MSEN is a screw-terminal aluminum electrolytic capacitor from Nichicon's LNR series, featuring a high 33,000 µF capacitance at 80 V rated voltage. Engineered as a radial can with screw terminals and bracket mounting, it is targeted for general-purpose power applications that require large bulk capacitance and robust ripple handling.

Key value comes from its high ripple-current capability, long 5,000‑hour endurance at 85°C, and broad operating temperature range from −40°C to +85°C, making it suitable for power smoothing, bulk energy storage, and DC-link applications in industrial and electronic equipment.

Key Features

• Capacitance & Voltage — 33,000 µF nominal capacitance with an 80 V rated voltage and ±20% tolerance at 120 Hz, 20°C for stable bulk energy storage.
• High Ripple-Current Capability — 9.20 A low-frequency ripple at 120 Hz and 10.58 A high-frequency ripple at 100 kHz to support high-current power circuits and smoothing duties.
• Endurance and Reliability — Rated for 5,000 hours at 85°C under rated DC bias plus ripple current; capacitance change remains within ±15% after endurance testing per the series specification.
• Low Loss and Controlled Leakage — Specified tan δ of 0.2 (20°C, 120 Hz) and measured leakage current of 4,870 µA, supporting predictable performance in long-duration and hold-up applications.
• Robust Mechanical Package — Radial can with screw terminals and standard 3-leg bracket for φ51 mm body diameter (body size φ51 × 120 mm), providing secure connections for high-current wiring.
• Wide Operating Temperature — Operates from −40°C to +85°C to accommodate a range of ambient conditions typical in industrial and commercial equipment.
• RoHS Compliant — Manufactured in accordance with RoHS requirements.

Typical Applications

• Power Supply Energy Storage — Bulk filtering and hold-up capacity for high-voltage DC power supplies where large capacitance and ripple handling are required.
• DC-Link and Motor Drive Support — Provides bulk smoothing and transient energy support in inverter/DC-link stages that require substantial charge storage and high ripple-current tolerance.
• Industrial Power Electronics — Useful in factory automation and industrial equipment for voltage stabilization and energy buffering under continuous load.
• UPS and Backup Systems — Bulk capacitor for intermediate energy storage and smoothing in uninterruptible power supplies and power conditioning modules.

Unique Advantages

• High Bulk Capacitance at 80 V — 33,000 µF provides significant energy storage in a single component, reducing the number of parts required for hold-up and smoothing functions.
• Strong Ripple Handling — 9.20 A (120 Hz) and 10.58 A (100 kHz) ripple ratings support both low- and high-frequency ripple environments, improving thermal stability and lifetime in high-current designs.
• Proven Endurance — 5,000‑hour endurance at 85°C under rated conditions delivers predictable long-term performance and design margin for continuous-operation systems.
• Screw-Terminal Mechanical Robustness — Screw terminals and bracket mounting simplify secure, low-resistance connections for high-current wiring, aiding assembly and maintenance in heavy-duty installations.
• Measured Electrical Characteristics — Specified tan δ and leakage current values allow engineers to model loss and standby dissipation accurately during design and thermal analysis.
• Manufactured by an Established Vendor — Part of Nichicon’s LNR series, enabling traceable production and documented series specifications for engineering validation.
