LNR1E333MSE

The LNR1E333MSE is a Nichicon LNR series aluminum electrolytic capacitor in a screw‑terminal radial can package. It provides 33,000 µF capacitance at 25 V with a screw terminal mounting style and is optimized for general‑purpose, high‑current DC energy storage and smoothing in industrial and power supply applications.

Key performance attributes include high ripple handling (6.2 A at 120 Hz and 7.13 A at 100 kHz), a rated operating temperature range of −40 °C to +85 °C, a specified endurance of 5,000 hours at 85 °C, and RoHS compliance—making it suitable for demanding, long‑life power designs that require reliable bulk capacitance.

Key Features

• High Capacitance: 33,000 µF (33 mF) nominal capacitance for bulk energy storage and smoothing of DC rails.
• Rated Voltage and Tolerance: 25 V rated voltage with ±20% capacitance tolerance at 120 Hz, 20 °C.
• Screw Terminal Mounting: Radial can with screw terminals for secure high‑current connections and straightforward installation or replacement.
• Ripple Current Capability: 6.2 A at 120 Hz (low frequency) and 7.13 A at 100 kHz (high frequency) for effective filtering under heavy ripple loads.
• Endurance and Temperature: Rated for 5,000 hours at 85 °C; operating temperature range −40 °C to +85 °C to support extended service life in elevated ambient conditions.
• Leakage and Loss: Specified leakage current of 2,720 µA and a tangent of loss angle (tan δ) up to 0.35, providing defined electrical behavior for design calculations.
• Form Factor: Compact φ35 × 80 mm can (L: 80 mm × D: 35 mm) suitable where high capacitance density and screw‑terminal connections are required.
• Compliance and Production: RoHS‑compliant and available in mass production packaging (cardboard packing).

Typical Applications

• Power supply bulk smoothing: Large capacitance and high ripple current ratings make it well suited to DC bus smoothing and bulk energy storage in power supplies and converters.
• Industrial power electronics: Screw‑terminal mounting and high ripple capability support motor drives, inverters, and industrial controllers that require reliable high‑current capacitors.
• Telecom and backup systems: Use as bulk energy reservoirs and smoothing capacitors in telecom power modules and uninterruptible power systems where long service life is required.

Unique Advantages

• Substantial energy storage: 33,000 µF provides significant bulk capacitance to reduce voltage ripple and support transient loads.
• High ripple handling: Combined low‑ and high‑frequency ripple ratings (6.2 A / 7.13 A) enable reliable performance across a range of switching frequencies.
• Robust thermal endurance: 5,000 hours at 85 °C endurance offers predictable lifetime behavior for high‑temperature applications.
• Serviceable screw terminals: Screw terminal connections allow secure, low‑impedance terminations and ease of onsite service or replacement.
• Defined electrical parameters: Specified tan δ and leakage current values aid accurate circuit simulation and margining in designs.
• Regulatory compliance: RoHS‑compliant construction aligns with environmental requirements for commercial and industrial products.
