LNR1J334MSEB

The LNR1J334MSEB is an aluminum electrolytic capacitor in a screw-terminal, radial can package designed for high-capacitance general-purpose power applications. With a rated voltage of 63 V and a nominal capacitance of 330,000 µF (330 mF), it provides substantial bulk energy storage and smoothing in systems requiring robust DC filtering.

Key attributes include high ripple current capability, long endurance at elevated temperature, and screw-terminal mounting for secure electrical and mechanical connections—making it suited to demanding industrial and power-electronics environments.

Key Features

• High Capacitance — 330,000 µF (330 mF) nominal capacitance for large bulk energy storage and extended hold-up capacity.
• Voltage Rating — Rated at 63 V to support higher-voltage DC bus and power-supply architectures within the specified range.
• Screw-Terminal, Radial Can Package — Screw terminal mounting provides reliable, low-resistance connections for high-current applications; radial can with screw terminals and standard mounting brackets for φ51 and larger bodies.
• High Ripple Current Capability — Low-frequency ripple current of 31.2 A at 120 Hz and high-frequency ripple current of 35.88 A at 100 kHz to support heavy AC ripple conditions on DC rails.
• Leakage and Loss Characteristics — Specified leakage current up to 5,000 µA and a tan δ of 0.6 (measured at 20°C, 120 Hz), enabling predictable loss and self-discharge behavior.
• Endurance and Temperature Range — Rated for 5,000 hours at 85°C with operating temperature range from −40°C to +85°C; endurance limits include capacitance change within ±15% after life test and leakage no greater than initial specified value.
• RoHS Compliant — Meets RoHS environmental requirements.
• Mechanical Dimensions — Body diameter φ90 with length 220 mm (approx. L:22 cm × D:9 cm) and standard 3-leg bracket configuration; nominal bolt diameter for φ90 is M5.

Typical Applications

• Power-supply bulk storage — Large capacitance and high ripple current support smoothing and hold-up on DC power rails.
• Industrial power systems — Robust screw-terminal mounting and high ripple tolerance for use in industrial power modules and assemblies.
• Energy buffering for converters and inverters — Substantial charge reservoir and endurance at 85°C for DC-link or buffering tasks in high-energy systems.

Unique Advantages

• Substantial stored energy: The 330,000 µF capacitance delivers a large charge reservoir for extended hold-up and smoothing without parallel arrays.
• Robust high-current handling: Rated ripple currents of 31.2 A (120 Hz) and 35.88 A (100 kHz) reduce thermal stress and enable stable operation under heavy ripple loads.
• Secure screw-terminal connections: Screw terminals with standard bracket mounting simplify integration into systems requiring high-current, low-impedance connections.
• Designed for elevated-temperature endurance: 5,000-hour life at 85°C with defined limits for capacitance change and leakage ensures predictable long-term performance.
• Clear electrical characteristics: Specified tan δ and leakage current values allow accurate thermal and leakage budgeting in designs.
• Environmentally compliant: RoHS compliance supports regulatory and procurement requirements.
