LNY2G183MSEJBB

The LNY2G183MSEJBB is an aluminum electrolytic capacitor in a screw-terminal radial can package, rated 18,000 µF at 400 V. It is designed for general-purpose power applications where high capacitance, high-voltage handling and robust ripple-current capability are required.

With a φ90 × 230 mm form factor (L: 23 × D: 9 cm) and screw-terminal mounting, this part is suited for equipment downsizing while delivering sustained performance across a –40 °C to +85 °C operating range and a rated load life of 2,000 hours at 85 °C under applied ripple current. The device is RoHS compliant.

Key Features

• High Capacitance and Voltage — 18,000 µF nominal capacitance at a 400 V rating for bulk energy storage and smoothing in high-voltage power rails.
• Screw Terminal Radial Can Package — Robust screw-terminal connections with a radial can package ideal for secure mechanical mounting and high-current connections; nominal bolt diameter for φ90 size is M5.
• Designed for Equipment Downsizing — High capacitance in a φ90 × 230 mm package supports compact power system layouts.
• High Ripple-Current Capability — 30.6 A at 120 Hz and 42.84 A at 10 kHz, enabling effective handling of AC ripple in power conversion and filtering applications.
• Extended Load Life — Rated load life of 2,000 hours at 85 °C with applied rated ripple current; performance is specified after restoration to 20 °C per the datasheet endurance conditions.
• Wide Operating Temperature — Specified for operation from –40 °C to +85 °C.
• Leakage Current Specification — After 5 minutes at rated voltage, leakage current is ≤ 3√(C·V) µA or 5 mA, whichever is smaller (at 20 °C), providing predictable standby leakage behavior.
• Insulation and Voltage Proof — Insulation resistance >100 MΩ at DC 500 V between terminal and bracket; withstands AC 2,500 V for 1 minute without abnormality.
• Regulatory Compliance — RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• Power supply bulk smoothing — Bulk energy reservoir for high-voltage power supplies, improving voltage stability under load.
• DC-link energy storage — Supports DC-link filtering in power conversion equipment where high capacitance and high ripple current are required.
• Industrial power equipment — Suitable for general-purpose industrial devices that demand robust high-voltage capacitors with screw-terminal connections.

Unique Advantages

• High stored energy in a compact package — 18,000 µF at 400 V enables reduced system footprint while maintaining bulk capacitance for energy buffering.
• Reliable power handling — Specified ripple-current ratings at 120 Hz and 10 kHz support sustained AC stress without immediate performance degradation.
• Durable mounting and connections — Screw terminals with M5 nominal bolt interface provide secure, serviceable electrical and mechanical attachment.
• Thermal and lifecycle specification — Rated for –40 °C to +85 °C operation and 2,000-hour load life at 85 °C, enabling predictable lifetime planning.
• Measured electrical assurances — Defined leakage current limits and insulation resistance requirements allow straightforward validation during qualification and incoming inspection.
• Regulatory readiness — RoHS compliance simplifies use in designs requiring restricted-substance compliance.
