LNR2C333MSEN

The LNR2C333MSEN is a screw-terminal aluminum electrolytic capacitor from Nichicon's LNR series, offering 33,000 µF capacitance at a 160 V rating. It is a radial can with screw terminals designed for general-purpose power applications that require high bulk capacitance and robust endurance.

Key value propositions include high capacitance density, a 160 V working voltage, and designed endurance for sustained operation at elevated temperatures (85°C), making it suitable where long-term bulk energy storage and ripple handling are required.

Key Features

• High Capacitance: 33,000 µF (33 mF) nominal capacitance for bulk energy storage and smoothing.
• Rated Voltage: 160 V DC rated voltage to support higher-voltage power rails within its specified range.
• Endurance at Elevated Temperature: Rated for 5,000 hours at 85°C under DC bias plus rated ripple current; after the endurance test the capacitor meets defined limits for capacitance change, tan δ, and leakage current per the datasheet.
• Leakage Current: Specified leakage current of 5,000 µA; datasheet guidance also defines leakage limits as not more than 3√(C·V) (µA) or 5 mA, whichever is smaller, after 5 minutes at 20°C.
• Loss Tangent (tan δ): Specified tan δ (DF) of 0.25, with datasheet limits and measurement conditions provided at 120 Hz, 20°C.
• Ripple Current Capability: 19.2 A at 120 Hz and 23.04 A at 100 kHz to support AC ripple and transient power demands.
• Mechanical & Mounting: Screw terminal radial can package (φ90 × 140 mm) with robust screw terminals for secure connections in panel- or chassis-mounted power assemblies.
• Operating Temperature Range: –25°C to +85°C (specified for the 160 V rating in the datasheet).
• Capacitance Tolerance: ±20% at 120 Hz, 20°C.
• RoHS Compliant: Meets RoHS environmental requirements.

Typical Applications

• General-Purpose Power Systems: Bulk smoothing and energy storage where high capacitance and a 160 V rating are required for general-purpose equipment.
• Power Supply Filtering: DC link and output filtering in power supplies that need high ripple current handling and long endurance at up to 85°C.
• Industrial Electronics: General-purpose industrial power assemblies that benefit from screw-terminal mounting and a large radial can form factor for secure installation.

Unique Advantages

• Large Capacitance in a Single Device: 33,000 µF provides substantial bulk charge storage without the need for parallel arrays, simplifying BOM and layout.
• High Voltage Capability: 160 V rating allows use on higher-voltage rails while maintaining the benefits of aluminum electrolytic construction.
• Designed Endurance: 5,000 hours at 85°C under rated conditions gives predictable long-term behavior for continuous-duty applications.
• Robust Mechanical Termination: Screw terminal radial can package enables secure, low-resistance connections in chassis- or bracket-mounted designs.
• Clear Performance Metrics: Specified ripple currents at 120 Hz and 100 kHz, leakage current value, and tan δ provide measurable parameters for design verification.
