LNR2A333MSE

The LNR2A333MSE is a screw-terminal aluminum electrolytic capacitor in Nichicon’s LNR series, configured as a radial can with screw terminals for secure power connections. With a rated capacitance of 33,000 µF and a 100 V rating, it is designed for general-purpose power applications requiring high bulk capacitance and durable electrolytic performance.

Key attributes include long-term endurance (5,000 hours at 85°C), a wide operating temperature range (−40°C to +85°C), and high ripple current capability, making it suitable for systems that demand sustained energy storage and robust DC bias handling.

Key Features

• High Capacitance — 33,000 µF (33 mF) rated capacitance provides significant bulk energy storage for power smoothing and decoupling.
• 100 V Rated Voltage — Designed for up to 100 V DC applications, enabling use in higher-voltage power rails within its rated limits.
• Screw Terminal Mounting — Radial can package with screw terminals offers secure, low-resistance mechanical and electrical connections for high-current interfaces.
• Long Endurance — Specified for 5,000 hours at 85°C under DC bias plus rated ripple current; after the endurance test, capacitance change remains within ±15% and leakage current remains at or below initial specifications.
• Wide Operating Temperature — Operational from −40°C to +85°C (for 10 to 100 V range), with defined impedance stability at low temperatures (Z(−40°C)/Z(+20°C) ≤ 12).
• Ripple Current Capability — Rated ripple currents of 10 A at 120 Hz and 11.5 A at 100 kHz support high-current AC components and filtering requirements.
• Leakage Current Specification — After 5 minutes at rated voltage, leakage current is limited to the smaller of 3√(C·V) µA or 5 mA (C in µF, V in V), enabling predictable bias behavior.
• RoHS Compliant — Conforms to RoHS requirements for environmental compliance.
• Physical Dimensions — Body dimensions approximately φ51 × 140 mm (L: 14 × D: 5.1 cm), supplied with mounting brackets for secure installation.

Typical Applications

• Power Supply Bulk Filtering — Provides substantial capacitance for bulk energy storage and smoothing on mid- to high-voltage DC rails up to 100 V.
• Industrial Power Electronics — Screw-terminal construction and high ripple current ratings support robust connections and sustained AC ripple handling in industrial converters and inverters.
• Energy Storage / Hold-up — High capacitance and long endurance make it suitable for short-term energy hold-up and buffering in systems requiring reliable DC support.

Unique Advantages

• Substantial Bulk Storage: 33,000 µF delivers large energy reserve within a single component, reducing the need for parallel capacitor arrays.
• High-Voltage Capability: 100 V rating allows deployment on higher-voltage buses while maintaining capacitor lifetime specifications.
• Secure Screw-Terminal Interface: Robust mechanical and electrical connection suited for high-current terminals and repeated maintenance.
• Documented Endurance: 5,000-hour endurance at 85°C with defined limits on capacitance change and leakage provides measurable lifecycle expectations.
• Predictable Leakage Behavior: Leakage current defined by the 3√(C·V) or 5 mA rule enables straightforward bias current budgeting in designs.
• Wide Temperature Range: −40°C to +85°C operation with specified impedance stability ensures usable performance across common industrial temperature extremes.
