LNT1C333MSE

The LNT1C333MSE is a screw-terminal aluminum electrolytic capacitor in Nichicon’s LNT series, offering 33,000 µF capacitance at a 16 V rating. Engineered as a radial, can-style screw terminal device, it provides bulk energy storage and smoothing for general-purpose power applications.

Key performance characteristics include a wide operating temperature range (−40 °C to +105 °C), a rated endurance of 2,000 hours at 105 °C, and RoHS compliance—making it suitable for robust industrial and commercial power designs that require high capacitance and reliable ripple handling.

Key Features

• High Capacitance: 33,000 µF (33 mF) effective bulk capacitance for energy storage and smoothing in power systems.
• Rated Voltage and Tolerance: 16 V rated voltage with capacitance tolerance of −20% to +20% (±20% at 120 Hz, 20 °C), suitable for DC power rails.
• Temperature and Endurance: Operating range −40 °C to +105 °C with a rated life of 2,000 hours at 105 °C under the specified ripple conditions.
• Low and High Frequency Ripple Capability: Designed for demanding ripple environments with 5.2 A at 120 Hz (low frequency) and 5.98 A at 100 kHz (high frequency) ripple current ratings.
• Electrical Loss and Leakage: Tangent of loss angle (tan δ) of 0.45 measured at 20 °C, 120 Hz, and a measured leakage current of 2,170 µA.
• Rugged Mechanical Package: Radial can with screw terminals (φ35 × 80 mm) for secure connections and easy mounting in power assemblies.
• Regulatory Compliance: RoHS compliant to support environmentally conscious designs.

Typical Applications

• General-purpose power supplies: Provides bulk capacitance for smoothing and energy storage on DC rails where high capacitance and screw-terminal connections are needed.
• Industrial power modules: Suited for supply filtering and decoupling in industrial power electronics that operate across −40 °C to +105 °C.
• Backup and hold-up circuits: High capacitance and rated ripple current support hold-up and temporary energy delivery in backup power designs.

Unique Advantages

• Substantial bulk capacitance: 33,000 µF provides significant energy storage in a single component, reducing part count for large-capacitance requirements.
• Screw-terminal convenience: Robust screw terminals enable reliable, low-resistance connections for high-current power paths and simplify rework or replacement.
• Wide operating temperature range: −40 °C to +105 °C allows deployment in temperature-varied environments common to industrial and commercial systems.
• High ripple handling: Specified low- and high-frequency ripple currents (5.2 A at 120 Hz and 5.98 A at 100 kHz) support mixed-frequency power converter applications.
• Designed endurance: 2,000-hour life at 105 °C under rated ripple conditions for predictable long-term performance planning.
• RoHS compliant: Meets environmental directive requirements for restricted substances.
