LNT1J333MSEB

The LNT1J333MSEB is a screw-terminal aluminum electrolytic capacitor from Nichicon’s LNT series, designed for general-purpose power applications. It delivers 33,000 µF capacitance at a 63 V rating with screw-terminal mounting and a rugged radial can package.

Engineered for elevated ripple handling and extended operating temperature, this capacitor is targeted at designs requiring high bulk energy storage, high ripple current capability, and long endurance at elevated temperatures up to 105°C.

Key Features

• Capacitance & Voltage 33,000 µF nominal capacitance with a rated voltage of 63 V and ±20% tolerance for bulk energy storage and voltage support.
• High Ripple Current Supports 9.4 A low-frequency ripple current (120 Hz) and 10.81 A high-frequency ripple current (100 kHz), enabling effective smoothing in power stages.
• Temperature & Endurance Operating range of −40°C to +105°C with a rated endurance of 2,000 hours at 105°C under DC bias plus rated ripple current.
• Electrical Loss & Leakage Tangent of loss angle (tanδ) measurement: 0.3 (measured at 20°C, 120 Hz). Specified leakage current: 4,320 µA.
• Robust Mechanical Design Screw terminal, radial can package (φ63.5 × 100 mm length) with M5 terminal hardware dimensions for secure electrical connections.
• Compliance & Availability RoHS compliant and listed as mass production status.

Typical Applications

• Power supply bulk filtering — Large 33,000 µF capacitance and 63 V rating provide bulk energy storage and smoothing for DC link and main power rails.
• High-ripple power stages — Rated ripple currents of 9.4 A (120 Hz) and 10.81 A (100 kHz) support frequent current cycling in switching supplies and converters.
• Industrial and control equipment — Wide operating temperature range (−40°C to +105°C) and 2,000-hour endurance at 105°C suit equipment exposed to elevated temperatures and continuous operation.

Unique Advantages

• High bulk capacitance: 33,000 µF provides significant energy storage in a single component, reducing the need for parallel capacitors.
• Superior ripple handling: Specified ripple currents at both low and high frequency enable reliable performance in a range of converter topologies.
• Elevated temperature endurance: Rated for operation up to 105°C with a 2,000-hour life rating at that temperature under rated conditions, supporting long-term reliability in hot environments.
• Screw-terminal connectivity: M5 screw terminals and a radial can form factor deliver secure, low-inductance connections for high-current applications.
• Clear electrical characterization: Specified tanδ (0.3 at 20°C, 120 Hz) and measured leakage current provide predictable behavior for design validation.
• RoHS compliant and production-ready: Conforms to RoHS requirements and is available in mass-production quantities.
