LNC2H222MSEGBN

The LNC2H222MSEGBN is a screw-terminal aluminum electrolytic capacitor designed for high-ripple, high-voltage applications. It delivers 2.2 mF (2200 µF) capacitance at a 500 V rating in a radial can with screw terminals and is polarized for DC energy-storage and smoothing duties.

Engineered for industrial power electronics, this Nichicon LNC-series part is suited to inverter circuitry, AC servomotor drives and other applications that demand high-frequency charge/discharge capability, elevated ripple-current capability and a dependable load life at elevated temperature. It is RoHS compliant and optimized for compact, high-performance power designs.

Key Features

• Capacitance & Voltage: 2.2 mF (2200 µF) rated at 500 V with capacitance tolerance of ±20% (at 120 Hz, 20°C).
• Screw-Terminal Radial Can: Radial package with screw terminals provides secure, serviceable connections for power assemblies.
• High Ripple Current Capability: Supports 14.2 A ripple current at 120 Hz and 19.88 A at 100 kHz, enabling effective smoothing under heavy AC and high-frequency stress.
• Wide Operating Temperature: Specified for –40°C to +85°C operation to cover common industrial ambient conditions.
• Load Life: Rated for 5000 hours when subjected to rated ripple current at 85°C, supporting long-term operation in demanding applications.
• Charge–Discharge Endurance: Designed to meet endurance criteria after 50 million charge–discharge cycles (ΔV = rated voltage × 0.3, cycle 3 Hz) per series test conditions.
• Leakage and Insulation Characteristics: Leakage current after 5 minutes is ≤ 3√V (µA) or 5 mA, whichever is smaller; insulation resistance >100 MΩ at DC 500 V between terminal and bracket.
• Voltage Withstand: Withstands AC 2500 V for 1 minute between terminal and bracket without abnormality (series specification).
• Physical Size: Body dimensions approximately L: 10.0 cm × D: 6.35 cm for compact integration into power modules.
• Regulatory Compliance: RoHS compliant per the stated directive.

Typical Applications

• Industrial Power Supplies: Bulk smoothing and energy buffering in inverter-fed power supplies where high ripple and high voltage are present.
• Motor Drive & Inverter Circuits: DC link and regenerative circuits for AC servomotors and general inverters that require robust charge/discharge handling.
• High-Frequency Regenerative Systems: Applications with rapid charge–discharge cycles and high-frequency ripple where sustained ripple-current capability is required.
• Power Conversion Modules: Energy storage and filtering in compact power assemblies that benefit from screw-terminal mounting and high ripple performance.

Unique Advantages

• High ripple-current performance: Measured capability at both 120 Hz and 100 kHz (14.2 A and 19.88 A respectively) lets designers manage ripple heating and ESR-related losses effectively.
• Long-term reliability under load: 5000-hour load-life rating at 85°C when exposed to rated ripple current provides predictable longevity for industrial deployments.
• Designed for high-frequency duty: Series-level specification for endurance under tens of millions of charge–discharge cycles supports aggressive regenerative and pulsed-power use cases.
• Secure, serviceable connections: Screw-terminal construction simplifies installation and maintenance in field-serviceable power modules.
• Compact footprint for high-voltage use: Smaller-sized construction (relative to earlier LNX/LNK references in series documentation) helps reduce board and module space for high-voltage capacitors.
• Measurable electrical safeguards: Defined leakage, insulation resistance and voltage-proof criteria support predictable behavior during design verification and qualification.
