LNY2G123MSEHBB

The LNY2G123MSEHBB is a screw-terminal aluminum electrolytic capacitor from Nichicon’s LNY series, offering 12,000 µF capacitance at a 400 V rating. It is a polarized, radial can style capacitor designed for general-purpose applications that require high capacitance and high-voltage energy storage in a compact form factor.

Engineered for robust ripple performance and extended load life, this part supports equipment downsizing goals while meeting RoHS requirements.

Key Features

• High Capacitance & Voltage — 12,000 µF nominal capacitance with a 400 V rated voltage for substantial bulk energy storage and smoothing in high-voltage circuits.
• Screw Terminal Mounting — Radial can with screw terminals (M5 nominal bolt) for secure, low-resistance electrical connections and straightforward mechanical installation.
• Endurance at Elevated Temperature — Load life of 2000 hours when rated ripple current is applied at 85°C, supporting reliable operation under continuous ripple stress.
• Ripple Current Capability — Rated ripple currents of 26 A at 120 Hz and 36.4 A at 10 kHz, enabling effective filtering and decoupling across low and high frequency ranges.
• Wide Operating Temperature Range — Specified to operate from −40°C to +85°C to accommodate a broad set of environmental conditions.
• Leakage and Tolerance Specifications — Capacitance tolerance ±20% (120 Hz, 20°C); leakage current after 5 minutes is limited to 3√CV (µA) or 5 mA, whichever is smaller.
• Compact Package for High Capacitance — Physical size φ76.2 × 220 mm (L), enabling high capacitance in a space-efficient cylinder; packaged for mass production with cardboard packing.
• Regulatory Compliance — RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• General-Purpose Power Systems — Bulk energy storage and smoothing in general-purpose equipment that require high-capacitance, high-voltage components.
• Power Electronics Filtering — DC link smoothing and ripple filtering where sustained ripple current capability and long load life at elevated temperature are needed.
• Industrial Equipment — Energy buffering and decoupling in industrial power assemblies operating within −40°C to +85°C ambient ranges.

Unique Advantages

• Large Energy Density at High Voltage — 12,000 µF at 400 V provides significant bulk capacitance for high-voltage circuits without multiple parallel parts.
• Reliable Long-Term Performance — 2000-hour load life at 85°C under rated ripple current supports predictable end-of-life behavior for maintenance planning.
• High Ripple Handling — Specified ripple current ratings at both 120 Hz and 10 kHz allow designers to address a range of switching and line-frequency disturbances.
• Robust Mechanical Connection — Screw terminal construction with M5 nominal bolt sizing delivers secure, low-impedance connections for power applications.
• Designed for Equipment Downsizing — LNY series emphasis on higher capacitance helps reduce component count and board area when implementing bulk storage.
• Regulatory Alignment — RoHS compliance simplifies integration into designs targeting regions enforcing RoHS directives.
