LNT1K333MSEN

The LNT1K333MSEN is a screw-terminal aluminum electrolytic capacitor from Nichicon's LNT series, offering 33,000 µF capacitance at an 80 V rating. It is a polarized, radial can package with screw terminals designed for general-purpose electronic and power applications that require large bulk capacitance and secure mechanical mounting.

Engineered for elevated operating conditions, this capacitor is specified for operation from −40 °C to +105 °C, supports high ripple current, and provides a rated load life at elevated temperature suitable for demanding power environments.

Key Features

• High Capacitance: 33,000 µF (33 mF) nominal capacitance for substantial bulk energy storage and smoothing in power networks.
• Rated Voltage: 80 V DC rating to support medium-voltage power rails and energy storage applications.
• Screw Terminal Mounting: Radial can with screw terminals for robust electrical and mechanical connections in industrial assemblies.
• Wide Operating Temperature Range: Specified from −40 °C to +105 °C to maintain performance across broad ambient conditions.
• High Ripple Current Capability: 9.9 A at 120 Hz and 11.38 A at 100 kHz to accommodate substantial AC ripple and pulsating currents.
• Endurance / Load Life: Load life of 2,000 hours at +105 °C under rated ripple current (applies to 10–250 V range as defined by the series).
• Tolerance and Polarization: ±20% capacitance tolerance; polarized electrolytic design.
• RoHS Compliant: Meets RoHS directives (2011/65/EU, (EU)2015/863) for restricted substances.
• Compact Form Factor for Value: Package dimensions L: 10 cm × D: 7.62 cm with screw-terminal radial can simplifies panel or chassis mounting.

Typical Applications

• General-purpose power filtering: Bulk smoothing and filtering in general electronic equipment where large capacitance and secure terminal connections are required.
• Industrial power supplies: Energy reservoir and ripple absorption in medium-voltage power supply modules and control equipment.
• High-current DC systems: Local energy buffering in systems that present significant ripple current loads, leveraging the listed ripple current ratings.

Unique Advantages

• Large energy storage in a compact screw-terminal package: 33,000 µF capacitance combined with screw terminals provides a reliable solution for high-capacitance requirements without complex assembly.
• Rated for elevated temperatures: Specified operation to +105 °C and a 2,000-hour rated load life at that temperature supports sustained performance in hot environments.
• High ripple-current handling: Explicit ripple current specifications at 120 Hz and 100 kHz enable confident selection for AC and switching applications.
• Clear specification set: Tolerance, polarization, leakage, and endurance characteristics are defined, aiding predictable design and qualification.
• Regulatory compliance: RoHS conformity simplifies integration into products requiring restricted-substance compliance.
