LNY2V123MSEJ

The LNY2V123MSEJ is a screw‑terminal aluminum electrolytic capacitor providing 12,000 µF capacitance at a 350 V rating. It is part of Nichicon's LNY series designed for higher capacitance in a screw‑terminal, radial can package for general‑purpose use.

Key value comes from high bulk capacitance and robust ripple handling, combined with a rated operating range from −40 °C to 85 °C and a specified load life of 2000 hours at 85 °C—suitable where sustained high‑voltage smoothing and durability are required. The part is RoHS compliant.

Key Features

• High Capacitance and Voltage: 12,000 µF nominal capacitance with a 350 V rated voltage for substantial energy storage in a single screw‑terminal can.
• Screw‑Terminal Mounting: Radial can with screw terminals for secure mechanical and electrical connection in high‑current installations.
• Ripple Current Capability: Rated ripple current of 24.1 A at 120 Hz and 33.74 A at 100 kHz to support applications with significant AC ripple on DC rails.
• Reliability and Endurance: Load life specified as 2000 hours at 85 °C with rated ripple applied; designed for sustained operation at the upper operating temperature limit.
• Wide Operating Temperature Range: Specified operation from −40 °C to 85 °C with low‑temperature impedance stability (Z(−40 °C)/Z(+20 °C) ≤ 12).
• Leakage and Insulation Characteristics: Leakage current not more than 3√(C·V) µA or 5 mA after 5 minutes (at 20 °C); insulation resistance greater than 100 MΩ at DC 500 V between terminal and bracket.
• Voltage Withstand: No abnormality at AC 2500 V applied for 1 minute between terminal and bracket, demonstrating robust terminal insulation.
• Physical Form Factor: Radial can with screw terminals; dimensional references include φ90 × 110L and size L: 11 × D: 9 cm for system layout and bracket design.
• RoHS Compliance: Conforms to RoHS directive (2011/65/EU,(EU)2015/863).

Typical Applications

• General‑purpose power systems: Bulk energy storage and decoupling where 350 V rating and large capacitance are required for smoothing and hold‑up.
• High‑ripple DC link support: Circuits that impose significant ripple currents can leverage the specified ripple current capability at 120 Hz and 100 kHz.
• Equipment downsizing efforts: The LNY series is described as suited for equipment downsizing, offering higher capacitance density for compact power designs.

Unique Advantages

• Substantial energy density at high voltage: 12,000 µF at 350 V consolidates bulk capacitance into a single component, simplifying layout and reducing part count.
• Robust ripple handling: High rated ripple currents at both low and high frequencies support demanding power conditioning and DC link duties.
• Designed for continuous operation: 2000 hours load life at 85 °C provides predictable performance for applications operating at elevated temperatures.
• Secure screw‑terminal connections: Screw terminals enable dependable electrical and mechanical attachment in high‑current systems.
• Low‑temperature stability: Defined impedance stability to −40 °C (Z ratio ≤ 12) helps maintain performance across a broad temperature span.
• Compliance and quality checks: Leakage, insulation resistance, and voltage proof specifications support confident integration into regulated designs.
