LNY2G392MSEGBN

The LNY2G392MSEGBN is a screw-terminal aluminum electrolytic capacitor designed for high-voltage, high-capacitance bulk energy storage. It features a 400 V rated voltage and 3.9 mF capacitance in a radial can with screw terminals for secure mechanical and electrical connections.

Engineered for general-purpose applications and equipment downsizing, this capacitor provides sustained performance across a –40 °C to +85 °C operating range with a rated load life of 2000 hours at 85 °C. The part is RoHS compliant.

Key Features

• High voltage and capacitance: Rated for 400 V with 3.9 mF capacitance, providing bulk energy storage for 400 V rails.
• Screw-terminal mounting: Radial can package with screw terminals for robust electrical connections and repeatable installation.
• Designed for equipment downsizing: Higher capacitance density suited where reduced component count and compact power assemblies are required.
• Wide operating temperature: Specified for –40 °C to +85 °C to support a broad range of ambient conditions.
• Load life endurance: Rated for 2000 hours with application of rated ripple current at 85 °C, meeting endurance requirements for sustained operation.
• High ripple-current capability: Rated ripple current of 14.2 A at 120 Hz and 19.88 A at 10 kHz to support high AC stress on power rails.
• Leakage current specification: After 5 minutes’ application of rated voltage, leakage current is limited to 3√CV (µA) or 5 mA, whichever is smaller (series specification).
• Polarized design with ±20% tolerance: Polar capacitor construction with capacitance tolerance of –20% to +20% (measured at 120 Hz, 20 °C).
• RoHS compliant: Conforms to the RoHS directive as indicated in the product information.
• Compact footprint for the class: Physical size L: 10.5 × D: 6.35 cm, facilitating integration into constrained layouts.

Typical Applications

• Power supply bulk filtering: Bulk energy storage and smoothing on 400 V DC rails where high capacitance and ripple handling are required.
• Power conversion assemblies: Support for DC-link or intermediate bus capacitors in power converters that benefit from higher capacitance in a screw-terminal package.
• Industrial equipment downsizing: Suitable for applications targeting reduced enclosure size while retaining necessary energy storage and ripple performance.

Unique Advantages

• High-voltage bulk capacity: 400 V rating combined with 3.9 mF capacitance supplies significant energy storage without resorting to parallel discrete parts.
• Robust ripple handling: Specified ripple currents at both 120 Hz and 10 kHz enable dependable performance under AC stress common in power electronics.
• Endurance at elevated temperature: 2000-hour load-life rating at 85 °C gives predictable lifetime behavior for sustained high-temperature operation.
• Secure mechanical and electrical termination: Screw-terminal construction provides a durable connection method for high-current and serviceable installations.
• Clear leakage-current limits: Leakage defined by 3√CV (µA) or 5 mA after 5 minutes ensures measurable, verifiable behavior during qualification and design.
• Regulatory compliance: RoHS compliance supports designs requiring regulated materials declarations.
