LNY2G103MSEJBN

The LNY2G103MSEJBN from Nichicon is a screw-terminal aluminum electrolytic capacitor providing 10,000 µF capacitance at a 400 V rating. Engineered as a high-capacitance, high-voltage bulk energy component, it is aimed at general-purpose power electronics where compact energy storage, robust electrical connection and reliable ripple performance are required.

Designed for applications that demand sustained ripple current and extended endurance at elevated temperature, this part supports equipment downsizing while meeting RoHS requirements (2011/65/EU, (EU)2015/863).

Key Features

• Capacitance & Voltage — 10,000 µF (10 mF) rated at 400 V, offering substantial bulk energy storage for high-voltage DC circuits.
• Screw-terminal package — Radial can with screw terminals enables secure, low-impedance electrical connections suitable for high-current use and repeatable assembly.
• Operating temperature & endurance — Rated for –40 °C to +85 °C with a specified load life of 2000 hours at 85 °C when rated ripple current is applied, supporting sustained operation under elevated thermal stress.
• High ripple-current capability — Specified ripple current: 22 A at 120 Hz and 30.8 A at 10 kHz, enabling effective filtering and smoothing in high-ripple environments.
• Polarized with defined leakage — Polarized device; leakage current after 5 minutes at 20 °C is limited to 3√(C·V) µA or 5 mA, whichever is smaller, providing predictable standby performance.
• Capacitance tolerance — ±20% (measured at 120 Hz, 20 °C), allowing designers to account for expected variation in bulk storage planning.
• Environmental compliance — RoHS compliant to 2011/65/EU and (EU)2015/863, supporting regulatory requirements for restricted substances.

Typical Applications

• High-voltage power supplies — Bulk energy storage and smoothing where 400 V rating and large capacitance are required to stabilize DC rails.
• Industrial power systems and inverters — DC-link and buffering roles that benefit from screw-terminal robustness and high ripple-current capability to handle switching currents.
• UPS and energy-buffer modules — Energy buffering and hold-up functions leveraging long load-life at elevated temperature for predictable performance over time.

Unique Advantages

• High-capacitance, high-voltage in a serviceable package: 10,000 µF at 400 V delivers significant bulk energy while screw terminals provide durable, serviceable connections for high-current installations.
• Strong ripple-current handling: Specified ripple currents of 22 A (120 Hz) and 30.8 A (10 kHz) reduce stress on upstream converters and improve thermal stability under real-world loading.
• Endurance under elevated temperature: 2000-hour load life at 85 °C with ripple current applied gives designers a measurable reliability baseline for thermal-stressed applications.
• Predictable electrical behavior: Clear leakage-current limits and ±20% capacitance tolerance allow accurate system-level margining and validation.
• Regulatory alignment: RoHS compliance simplifies adoption into products targeting regions with restricted substance requirements.
