LNT2W221MSECBN

The LNT2W221MSECBN from Nichicon is a screw-terminal aluminum electrolytic capacitor in the LNT series designed for general-purpose power applications. It combines a 220 µF capacitance with a 450 V rated voltage and screw-terminal mounting for secure, high-current connections in industrial and power-electronics systems.

This radial, can-style capacitor is specified for operation from −25°C to +105°C with a rated endurance of 5,000 hours at 105°C, making it suitable for applications that require sustained ripple handling and long-term thermal stability.

Key Features

• Capacitance & Tolerance — 220 µF nominal with capacitance tolerance of -20%~20% (±20% at 120 Hz, 20°C).
• High Voltage Rating — 450 V rated voltage for high-voltage DC filtering and energy storage tasks.
• Screw Terminal Mounting — Radial can with screw terminals for robust, low-resistance electrical and mechanical connections in power assemblies.
• Loss Tangent (tan δ) — tanδ (DF) = 0.2 measured at 20°C, 120 Hz for predictable AC loss behavior.
• Ripple Current Capability — Low-frequency ripple current 1.8 A at 120 Hz and high-frequency ripple current 2.52 A at 100 kHz to support demanding power-conditioning loads.
• Leakage Current — Specified leakage current of 940 µA after rated voltage application (measurement at 20°C).
• Operating Temperature & Endurance — Rated for −25°C to +105°C with a life/endurance rating of 5,000 hours at 105°C under specified conditions.
• Packaging & Production — Supplied in cardboard packing and available in mass production.
• RoHS Compliant — Conforms to RoHS requirements for restricted substances.
• Form Factor — Compact φ35 × 80 mm can (L: 8 × D: 3.5 cm) suitable for panel- or chassis-mounted power modules.

Typical Applications

• Power Supplies: Bulk smoothing and DC link energy storage in high-voltage power supplies and rectifier circuits where 450 V rating and high ripple handling are required.
• Motor Drives & Inverters: DC bus and filtering applications in industrial drive systems that need screw-terminal reliability and elevated temperature endurance.
• Power Conditioning: EMI/RFI filtering and decoupling in high-voltage converters, where stable tanδ and leakage specifications support predictable performance.

Unique Advantages

• High-Voltage Capability: 450 V rating enables use in higher-voltage power systems without series stacking of multiple components.
• Robust Mechanical Connection: Screw terminals provide secure electrical contact for high-current paths and simplify installation in field-serviceable equipment.
• Thermal Endurance: 5,000-hour rating at 105°C supports longer service life in elevated-temperature environments compared with lower-temperature alternatives.
• Clear Performance Data: Defined tanδ, ripple current (both low and high frequency), and leakage current specifications allow straightforward thermal and lifetime calculations.
• RoHS Compliance: Meets restricted-substance requirements for regulated designs and manufacturing processes.
• Production-Ready Supply: Cardboard packed and listed as mass production for reliable sourcing and assembly planning.
