LNT2G222MSEG

The LNT2G222MSEG is a screw-terminal aluminum electrolytic capacitor in Nichicon’s LNT series, offering 2200 µF capacitance at a 400 V rating in a radial can with screw terminals. Designed for general-purpose power electronics, it targets applications that require high-voltage energy storage, DC-link smoothing and robust ripple-handling in industrial systems.

Key value comes from a combination of high capacitance and voltage, elevated operating temperature capability up to 105°C with a 5,000‑hour endurance, and high ripple current ratings—delivering reliable smoothing and decoupling in demanding power environments.

Key Features

• Electrical Capacity: 2200 µF nominal capacitance with ±20% tolerance (measured at 120 Hz, 20°C), providing substantial energy storage for high-voltage circuits.
• High Voltage Rating: Rated voltage 400 V, suited for high-voltage DC-link and power supply applications.
• Low Loss Characteristic: Tangent of loss angle (tan δ) specified at 0.2 (measurement condition: 20°C, 120 Hz), supporting stable performance under AC ripple.
• High Ripple Current Capability: Rated low-frequency ripple current 11.5 A (120 Hz) and high-frequency ripple current 16.1 A (100 kHz), enabling effective handling of both mains-frequency and switching-frequency stress.
• Thermal and Endurance Ratings: Operating temperature range −25°C to +105°C with a rated life of 5,000 hours at 105°C when subjected to rated ripple and DC bias.
• Leakage Current: Specified leakage current of 2810 µA after rated voltage application (measured at 20°C), for predictable standby loss behavior.
• Mechanical / Mounting: Screw terminal radial can package (φ63.5 × 100L). Terminal design for φ63.5 size uses an M5 nominal bolt for secure, high-current connections.
• Manufacturing & Compliance: Mass-production status with cardboard packing and RoHS compliance for regulatory alignment.

Typical Applications

• Industrial Power Supplies: Energy storage and smoothing in high-voltage power supplies where 400 V rating and high capacitance reduce output ripple and stabilize DC rails.
• DC-Link / Motor Drives: Bulk DC-link smoothing and transient energy buffering in motor drives and inverters that demand high ripple capability and sustained operation at elevated temperature.
• Uninterruptible Power Supplies (UPS) and Telecom Power: Bulk storage for hold-up and filtering functions benefiting from the capacitor’s high capacitance and long endurance at 105°C.
• Renewable Inverter Systems: DC energy smoothing and ripple mitigation in inverter front-ends where high voltage and high ripple tolerance improve system reliability.

Unique Advantages

• Robust high-voltage energy storage: 2200 µF at 400 V provides substantial capacitance for bulk filtering and energy buffering in high-voltage circuits.
• High ripple-handling capability: Dual ripple ratings (11.5 A at 120 Hz and 16.1 A at 100 kHz) address both low-frequency and switching-frequency stresses common in power electronics.
• Designed for elevated-temperature endurance: 5,000-hour life at 105°C under rated conditions supports long-term reliability in harsh thermal environments.
• Secure, low-impedance terminal connection: Screw-terminal mounting with M5 nominal bolt (φ63.5 size) provides reliable mechanical and electrical connection for high-current applications.
• Predictable leakage and loss characteristics: Specified leakage current and tan δ simplify thermal and loss budgeting during design verification.
• Production-ready availability: Mass-production status and RoHS compliance facilitate integration into volume manufacturing with standard packing.
