LNY2G103MSEJ

The LNY2G103MSEJ is a screw-terminal aluminum electrolytic capacitor from Nichicon's LNY series, providing 10,000 µF of capacitance at a 400 V rated voltage. Designed for high-voltage bulk energy storage and smoothing, it combines large capacitance with robust ripple-current capability for demanding power-electronics and industrial applications.

With a rated operating range of −40°C to +85°C, a load life of 2000 hours at 85°C, and RoHS compliance, this radial can with screw terminals is intended for applications that require reliable high-voltage capacitance and secure mechanical mounting.

Key Features

• High Capacitance and Voltage: 10,000 µF rated capacitance at 400 V provides substantial energy storage for DC bus and bulk smoothing functions.
• Screw Terminal Mounting: Radial can with screw terminals (M5 bolt sizing for φ90) enables secure, low-impedance connections for high-current applications.
• High Ripple-Current Capability: Supports 22 A at 120 Hz (low frequency) and 30.8 A at 10 kHz (high frequency), helping manage ripple heating and extend operational life under AC ripple stress.
• Endurance and Temperature Range: Rated for 2000 hours at 85°C and operable from −40°C to +85°C, providing predictable aging characteristics in elevated-temperature environments.
• Leakage and Loss Characteristics: Specified leakage current up to 5000 µA and tangent of loss angle (tan δ) 0.25 at 20°C, 120 Hz—key parameters for design margin and thermal planning.
• Series-Level Reliability Tests: Series specifications include insulation resistance >100 MΩ at DC 500 V between terminal and bracket and AC 2500 V dielectric proof for 1 minute with no abnormality.
• Packaging and Status: Supplied in cardboard packing and available in mass production for production-volume sourcing.
• Regulatory Compliance: RoHS compliant (per series documentation), supporting regulatory requirements for restricted substances.

Typical Applications

• Power conversion and DC link: 400 V rating and 10,000 µF capacitance make this capacitor suitable for DC-link smoothing in power converters and inverters.
• Industrial power systems: High ripple-current capability and screw terminals support heavy-duty industrial power supplies and motor-drive DC buses.
• Uninterruptible power supplies (UPS) and energy storage modules: Large bulk capacitance for transient energy buffering and voltage stabilization.

Unique Advantages

• Significant bulk energy storage: 10,000 µF at 400 V delivers large stored energy per module to reduce ripple and support transient loads.
• Robust ripple handling: Dual ripple-current ratings (22 A at 120 Hz, 30.8 A at 10 kHz) reduce internal heating and improve reliability under AC stress.
• Secure, serviceable connections: Screw-terminal radial can design enables low-resistance wiring and straightforward mechanical fastening for high-current installations.
• Proven endurance at elevated temperature: 2000-hour load life at 85°C with rated ripple current provides predictable longevity for thermal-critical designs.
• Series-level electrical verification: Insulation resistance and dielectric proof tests offer documented reliability characteristics for system validation.
• Regulatory alignment: RoHS compliance supports deployment in environments requiring restricted-substance conformity.
