LNR1J333MSEN

The LNR1J333MSEN is a screw-terminal aluminum electrolytic capacitor designed for general-purpose power applications. It delivers very high capacitance in a robust radial can with screw terminals, intended for designs that require bulk energy storage, DC bus stabilization, or high-ripple handling.

Key value propositions include high capacitance (33 mF), a 63 V rated voltage, long endurance at elevated temperature (5000 hours at 85°C), and a mounting style that supports secure, serviceable connections.

Key Features

• Capacitance & Voltage: 33 mF (33,000 µF) nominal capacitance rated at 63 V, with a tolerance of ±20% (120 Hz, 20°C).
• Screw-Terminal Package: Radial can with screw terminals (φ51×80L body size; dimensions L: 8 × D: 5.1 cm) for secure mechanical and electrical connection in high-current assemblies.
• Endurance & Reliability: Rated for 5000 hours at 85°C (with D.C. bias plus rated ripple current). After endurance testing, capacitance remains within ±15% of initial value; tan δ and leakage remain within specified limits.
• Operating Temperature Range: –40°C to +85°C operating range suitable for a wide range of ambient conditions within the specified rating.
• Ripple Performance: Ripple current ratings of 8.8 A at 120 Hz and 10.12 A at 100 kHz support high-ripple applications when used within specified conditions.
• Loss Characteristic: Tangent of loss angle (tan δ) specified (0.25), enabling assessment of AC loss and heating under ripple conditions.
• Leakage Current Specified: After 5 minutes’ application of rated voltage at 20°C, leakage current not more than 3√(C·V) μA or 5 mA, whichever is smaller (C in μF, V in volts).
• Compliance & Packaging: RoHS compliant and supplied in cardboard packing; part is in mass production.
• Marking: Printed with black color lettering on a light blue sleeve for clear polarity and identification.

Typical Applications

• General-purpose power systems: Bulk capacitance for energy storage and DC smoothing in general-purpose electronic power designs.
• Power supply filtering: Filtering and ripple suppression where high capacitance and screw-terminal connections are required for robust current handling.
• High-ripple circuits: Circuits that require sustained ripple current handling up to the specified 8.8 A (120 Hz) and 10.12 A (100 kHz) ratings.

Unique Advantages

• High-capacitance density: 33,000 µF provides substantial bulk energy storage in a single component, reducing the need for parallel capacitors.
• Screw-terminal robustness: Secure screw terminals facilitate reliable, low-resistance connections and simplify installation and maintenance.
• Long-term durability at elevated temperature: 5000-hour endurance at 85°C supports long service life under sustained thermal stress when used within ratings.
• Quantified ripple capability: Published ripple current values at both low and high frequencies enable accurate thermal and lifetime budgeting in power designs.
• Clear specification of loss and leakage: tan δ and leakage current limits are specified, aiding thermal design and leakage budgeting early in development.
• Regulatory compliance and production readiness: RoHS compliance and mass-production availability simplify procurement and lifecycle planning.
