LNR1E333MSEN

The LNR1E333MSEN is a screw‑terminal aluminum electrolytic capacitor from Nichicon's LNR series, offering 33,000 µF capacitance at a 25 V rating. Built for general‑purpose power circuitry, it provides high bulk capacitance in a radial can with screw terminals and is available in mass production.

Key performance attributes include an 85°C rated temperature, a 5,000‑hour endurance at 85°C, specified low and high frequency ripple currents, and RoHS compliance—making it suitable where high capacitance, secure screw‑terminal connections, and proven endurance are required.

Key Features

• High Capacitance — 33,000 µF nominal capacitance (±20% tolerance) provides substantial bulk energy storage for power systems that require large smoothing reservoirs.
• Rated Voltage and Temperature — 25 V rated voltage with an operating temperature range of −40°C to +85°C and 5,000 hours endurance at 85°C for predictable performance under elevated temperatures.
• Screw Terminal Mounting — Radial can package with screw terminals for robust, low‑impedance connections suitable for repeated assembly and higher current terminations.
• Ripple Current Capability — Specified ripple handling of 6.2 A at 120 Hz (low frequency) and 7.13 A at 100 kHz (high frequency) to address both mains‑related and higher‑frequency ripple conditions.
• Leakage and Dissipation — Leakage current specified at 2,720 µA and tangent of loss angle (tanδ) up to 0.35 to support predictable loss and leakage characteristics in design calculations.
• Package and Size — φ35 × 80 mm can (L: 8 × D: 3.5 cm) in a radial, screw‑terminal package; shipped in cardboard packing and produced in mass production quantities.
• Regulatory — RoHS compliant, meeting environmental regulation requirements for lead‑restricted applications.

Typical Applications

• General‑Purpose Power — Intended for general‑purpose circuits that require large bulk capacitance and secure screw‑terminal electrical connections.
• Power Supply Smoothing — Provides bulk smoothing where specified ripple current (6.2 A at 120 Hz, 7.13 A at 100 kHz) and high capacitance are needed to mitigate voltage ripple.
• High‑Energy Reservoirs — Serves as a local energy reservoir in systems that require sustained charge storage at 25 V nominal rating and ±20% tolerance.

Unique Advantages

• Substantial Bulk Storage: 33,000 µF nominal capacitance gives designers a high-capacitance option without stacking multiple smaller capacitors.
• Screw‑Terminal Reliability: Screw terminals deliver mechanically secure, low‑resistance connections suitable for higher current paths and serviceability.
• Dual‑Frequency Ripple Ratings: Clear specifications for both low‑frequency (120 Hz) and high‑frequency (100 kHz) ripple current enable confident selection for mixed‑frequency environments.
• Thermal Endurance: 5,000 hours at 85°C endurance rating supports longer service life expectations under elevated operating temperatures.
• Predictable Loss and Leakage: Specified tanδ (0.35) and leakage current (2,720 µA) allow accurate thermal and leakage budgeting in system designs.
• Regulatory Compliance: RoHS compliance supports restrictions on hazardous substances in manufactured assemblies.

Why Choose LNR1E333MSEN?

The LNR1E333MSEN positions itself as a robust, high‑capacitance solution for general‑purpose power designs that require screw‑terminal mounting and defined ripple handling at both low and high frequencies. Its 25 V rating, ±20% tolerance, and long endurance at 85°C make it suitable for engineers specifying durable bulk capacitance with predictable leakage and dissipation characteristics.

This part is suited for designs where a single high‑value capacitor simplifies the bill of materials and mechanical layout while providing the endurance and terminal reliability expected from a mass‑produced component. RoHS compliance further supports environmental requirements for production assemblies.
