LNY2G102MSEFBN

The LNY2G102MSEFBN is a screw-terminal, aluminum electrolytic capacitor providing 1 mF (1000 µF) capacitance at a 400 V rating. Engineered for higher-capacitance, compact can-style applications, it delivers bulk energy storage and filtering for general-purpose equipment.

With an operating temperature range of –40 °C to +85 °C and a specified load life of 2000 hours at 85 °C under applied ripple, this capacitor is suited for equipment downsizing and designs that require secure screw-terminal connections and reliable ripple handling.

Key Features

• Rated Capacitance & Tolerance: 1 mF (1000 µF) with ±20% tolerance (120 Hz, 20 °C), providing defined bulk storage for smoothing and decoupling.
• High DC Voltage Rating: 400 V rated voltage for high-voltage power applications requiring robust DC bus support.
• Screw Terminal Package: Radial can with screw terminals (M5 nominal bolt for φ51 mm), enabling secure, low-inductance connections for high-current terminals.
• Rated Ripple Current: 6.4 A (Arms) at 120 Hz and 8.96 A at 10 kHz, allowing effective ripple absorption across common power frequencies.
• Thermal & Lifetime Performance: Operating range –40 °C to +85 °C and load life of 2000 hours at 85 °C when exposed to rated ripple current.
• Electrical Loss & Leakage: Tangent of loss angle (tan δ) 0.25 (measurement at 120 Hz, 20 °C) and measured leakage current example 1.89 mA; datasheet specifies leakage limits of 3√(C·V) µA or 5 mA (whichever smaller) after 5 minutes at 20 °C.
• RoHS Compliant: Constructed to meet RoHS directive requirements for reduced hazardous substances.
• Compact Can Dimensions: Diameter φ51 mm and length 60 mm, supporting higher capacitance in a relatively compact footprint for its class.

Typical Applications

• Power Supply Smoothing: Bulk capacitance for DC link and output filtering in general-purpose power supplies and converters.
• Equipment Downsizing: Higher capacitance in a compact screw-terminal can helps shrink power electronics assemblies where board space is constrained.
• Industrial & Commercial Power Modules: Use where secure screw-terminal mounting and multi-amp ripple handling are required in general-purpose equipment.

Unique Advantages

• High Voltage and Capacitance Combination: 400 V and 1000 µF in a single can delivers significant bulk energy for high-voltage circuits without multiple parallel parts.
• Screw-Terminal Reliability: Robust screw-terminal construction provides dependable mechanical and electrical connections for high-current terminations.
• Ripple Handling Across Frequencies: Specified ripple current at 120 Hz and 10 kHz supports filtering performance for both low- and higher-frequency ripple components.
• Designed for Compact Designs: φ51 mm by 60 mm size enables higher capacitance density to support equipment downsizing strategies.
• Validated Endurance: 2000-hour load life at 85 °C under rated ripple current provides a defined reliability envelope for thermal-stressed designs.
• Regulatory Compliance: RoHS compliance supports regulatory requirements for hazardous-substance reduction in assemblies.
