LNY2V123MSEHBB

The LNY2V123MSEHBB is a screw-terminal aluminum electrolytic capacitor designed for high-voltage bulk-energy and smoothing applications. It delivers 12,000 µF of capacitance at a 350 V rating with a ±20% tolerance, and is supplied in a radial can with screw terminals for secure, low-impedance connections.

Engineered for general-purpose power designs that require high capacitance, robust ripple handling and a compact footprint for equipment downsizing, this part is RoHS compliant and available in mass production with cardboard packing.

Key Features

• Capacitance & Voltage — 12,000 µF nominal capacitance with a 350 V rated voltage and ±20% tolerance (measured at 120 Hz, 20°C).
• High Ripple Current Capability — Low-frequency ripple current of 24.0 A at 120 Hz and high-frequency ripple current of 33.6 A at 10 kHz, supporting demanding AC ripple and transient conditions.
• Electrical Loss & Leakage — Loss tangent (tan δ) of 0.25 at 20°C and 120 Hz and specified leakage current up to 5,000 µA, allowing predictable performance in high-energy applications.
• Thermal & Lifetime — Rated for operation from −40°C to +85°C with a rated load life (endurance) of 2,000 hours at 85°C under rated ripple conditions.
• Package & Mounting — Radial can with screw terminals for robust electrical and mechanical connection; physical size provided as φ76.2 × 150L (L: 15 cm × D: 7.62 cm), simplifying mechanical integration.
• Compliance & Availability — RoHS-compliant construction and listed as mass production status with cardboard packing for standard shipment.

Typical Applications

• General-purpose power systems — Bulk energy storage and smoothing in high-voltage power supplies where high capacitance and ripple handling are required.
• Equipment downsizing — Provides high capacitance per package to support reduced system volume while maintaining performance in mature power designs.
• High-ripple environments — Suitable for circuits that experience sustained AC ripple or transient currents, leveraging its specified low- and high-frequency ripple ratings.

Unique Advantages

• High bulk capacitance at high voltage: 12,000 µF at 350 V delivers substantial stored energy for DC-link and smoothing roles.
• Strong ripple-handling capability: 24 A (120 Hz) and 33.6 A (10 kHz) ripple ratings enable reliable operation under sustained AC stress.
• Durability under elevated temperature: 2,000-hour rated life at 85°C provides a clear endurance baseline for thermal-stressed designs.
• Secure screw-terminal mounting: Screw terminals provide low-impedance, mechanically robust connections for high-current applications.
• Predictable electrical characteristics: Specified tan δ and leakage current values allow engineers to model dissipation and standby losses accurately.
• Regulatory readiness and supply: RoHS compliance and mass-production availability support deployment in production programs.
