LNT1A333MSE

The LNT1A333MSE is a screw‑terminal aluminum electrolytic capacitor from Nichicon’s LNT series. It provides very high capacitance in a radial can with screw terminals for secure, low‑impedance connections in general‑purpose power designs.

Designed for applications that require large bulk capacitance and robust thermal endurance, this part delivers 33,000 µF at 10 V with rated ripple handling and an extended operating temperature range down to −40 °C up to 105 °C.

Key Features

• High Capacitance: 33,000 µF (33 mF) rated capacitance for bulk energy storage and smoothing.
• Rated Voltage: 10 V nominal rating suitable for low‑voltage power rails.
• Screw‑Terminal Mounting: Radial, can package with screw terminals for reliable mechanical and electrical connections in bench, rack, and chassis installations.
• Temperature Range & Endurance: Operating temperature −40 °C to 105 °C with a rated lifetime of 2,000 hours at 105 °C under rated ripple conditions.
• Ripple Current Capability: 4.8 A at 120 Hz and 5.52 A at 100 kHz, enabling sustained AC ripple handling in power applications.
• Leakage Current and Tolerance: Leakage current specified at 1,720 µA and capacitance tolerance ±20% (measured at 120 Hz, 20 °C).
• Compact Screw‑Terminal Can: Physical size φ35 × 80L (L: 8 × D: 3.5 cm) for high capacitance density in a relatively small footprint.
• Environmental Compliance: RoHS compliant per product documentation.

Typical Applications

• General‑purpose power systems: Bulk energy storage and smoothing on low‑voltage power rails where high capacitance is required.
• Industrial equipment: Decoupling and ripple filtering in control cabinets and power electronics that benefit from screw‑terminal mounting.
• Laboratory and rack installations: Systems that require a robust mechanical connection and easy serviceability using screw terminals.

Unique Advantages

• Large energy storage in a compact can: 33,000 µF at 10 V provides significant bulk capacitance while maintaining a φ35 can footprint.
• Secure electrical and mechanical connection: Screw‑terminal packaging ensures low‑resistance contact and reliable mounting for high‑current ripple conditions.
• High ripple handling across frequencies: Specified ripple current at both 120 Hz and 100 kHz supports performance in a range of power converter and filter designs.
• Wide operating temperature range: −40 °C to 105 °C allows deployment in environments with large temperature swings while maintaining specified performance.
• Proven endurance at elevated temperature: Rated for 2,000 hours at 105 °C under rated ripple current, consistent with the LNT series endurance specifications for this voltage range.
• Regulatory compliance: RoHS compliant for use in regions requiring restricted substance adherence.
