LNK2G103MSEJ

The LNK2G103MSEJ is a screw-terminal aluminum electrolytic capacitor designed for general-purpose power applications that require high capacitance at elevated DC voltages. It combines a 10,000 µF capacitance with a 400 V rating in a smaller-sized, radial can with screw terminals to support high-ripple, high-voltage circuits.

Built for continuous operation across a wide ambient range and a specified 5000-hour load life at 85°C, this RoHS-compliant capacitor is intended for designs where large energy storage, robust ripple-current handling, and secure screw-terminal connections are needed.

Key Features

• High capacitance: 10,000 µF nominal capacitance (10 mF) provides substantial bulk energy storage for smoothing and decoupling in high-voltage circuits.
• High-voltage rating: Rated voltage 400 V to support elevated DC bus and high-voltage power circuits.
• Screw terminal mounting: Radial can with screw terminals for secure, low-impedance connections suitable for high-current installations.
• High ripple-current capability: Rated ripple current of 24.2 A at 120 Hz and 33.88 A at 10 kHz (part-specific values) to support demanding AC ripple conditions.
• Long load life at temperature: Endurance specified as 5000 hours with rated ripple current at 85°C for reliable in-service life under continuous load.
• Operational temperature range: –25°C to +85°C to accommodate typical industrial ambient conditions.
• Polarized design with standard tolerance: Polarized capacitor with ±20% capacitance tolerance at 120 Hz, 20°C.
• Environmental compliance: RoHS compliant per product data.
• Leakage and reliability characteristics: Datasheet leakage-current limit defined as not more than 3√(C·V) µA or 5 mA (whichever is smaller) after 5 minutes at rated voltage; insulation resistance and voltage proof tests between terminal and bracket are specified in the series datasheet.
• Frequency performance: Series frequency coefficient of rated ripple current rises with frequency (e.g., coefficient 1.00 at 120 Hz and 1.40 at 10 kHz), supporting higher ripple capability at higher frequencies.

Typical Applications

• General-purpose power filtering: Bulk smoothing and decoupling in DC power rails where 10,000 µF at 400 V and high ripple current are required.
• High-voltage energy storage: Local energy reservoir for circuits operating at or near a 400 V DC bus.
• High-ripple power circuits: Circuits that present significant AC ripple across the capacitor benefit from the specified ripple-current ratings and frequency coefficients.
• Secure, high-current installations: Screw-terminal mounting provides a robust electrical and mechanical connection for repeated maintenance or high-current bus connections.

Unique Advantages

• Substantial energy density at high voltage: 10,000 µF at 400 V delivers large stored charge without the need for multiple smaller parts.
• Designed for sustained duty: 5000-hour endurance at 85°C under rated ripple current reduces replacement frequency in continuous-load applications.
• High ripple handling at multiple frequencies: Specified ripple currents at 120 Hz and 10 kHz, plus frequency coefficients, let engineers predict thermal stress across the operating band.
• Easy, reliable connections: Screw-terminal package simplifies wiring and offers a low-impedance path for high current, improving system reliability.
• Regulatory compliance: RoHS compliance supports equipment designs that must meet environmental directives.
• Wide ambient tolerance: –25°C to +85°C operating range supports deployment in a range of industrial environments.
