LNY2G122MSEFBN

The LNY2G122MSEFBN is a screw‑terminal aluminum electrolytic capacitor in Nichicon’s LNY series designed for general‑purpose high‑voltage energy storage and filtering. It delivers 1.2 mF capacitance at a 400 V rating with a screw‑terminal can package, targeting industrial and power electronics applications that require a robust, serviceable high‑capacitance solution.

Key value comes from higher capacitance in a radial screw‑terminal package, a 2000 h load life at 85°C, and specifications tuned for ripple handling and wide operating temperatures, enabling reliable bulk energy smoothing and filtering in high‑voltage systems.

Key Features

• Capacitance and Rated Voltage — 1.2 mF (1200 µF) nominal capacitance at a 400 V rated voltage, suitable for high‑voltage energy storage and smoothing.
• Tolerance and Loss — ±20% capacitance tolerance (120 Hz, 20°C) with a tangent of loss angle (tan δ) of 0.25, useful for calculating expected ESR and dissipation in designs.
• Leakage Current — Specified leakage current of 2070 µA, enabling engineers to budget standby currents and perform leakage‑based safety calculations.
• Ripple Current Capability — 7.1 A at 120 Hz and 9.94 A at 10 kHz ripple current ratings to support significant AC ripple in power conversion and filtering stages.
• Endurance and Temperature Range — Rated for 2000 hours life at 85°C under rated ripple conditions and an operating temperature range of −40°C to +85°C for broad environmental suitability.
• Screw‑Terminal Mechanical Package — Radial can with screw terminals (M5 nominal bolt) and φ51 × 65 mm dimensions (L: 6.5 × D: 5.1 cm) for secure, serviceable connections in panel or chassis installations.
• RoHS Compliance and Packaging — RoHS‑compliant construction and supplied in cardboard packing for production‑scale handling.
• Low‑Temperature Stability — Impedance ratio Z(−40°C)/Z(+20°C) up to 12, useful for designs that must account for increased impedance at low ambient temperatures.

Typical Applications

• Industrial Power Supplies — Bulk energy storage and smoothing in high‑voltage AC/DC and DC/DC supplies where high capacitance and robust ripple handling are required.
• Inverters and Motor Drives — DC link and smoothing capacitors in inverter or drive systems that require 400 V class capacitance and sustained ripple endurance.
• Backup and UPS Modules — Energy buffering for short‑term hold‑up and filtering duties in uninterruptible power modules and standby power systems.
• Power Conversion Equipment — Filtering and decoupling in high‑voltage conversion stages where screw‑terminal connections provide secure, maintainable terminations.

Unique Advantages

• High‑Voltage, High‑Capacitance in a Serviceable Package: 1.2 mF at 400 V provides substantial energy density while screw terminals allow robust bolted connections and field serviceability.
• Designed for Ripple Endurance: Rated ripple currents of 7.1 A (120 Hz) and 9.94 A (10 kHz) combined with a 2000 h life at 85°C let designers size capacitors for continuous ripple conditions with predictable aging.
• Wide Operating Temperature Range: −40°C to +85°C operation and defined impedance behavior at low temperature enable deployment across varied ambient conditions.
• Predictable Leakage and Loss Characteristics: Specified leakage current (2070 µA) and tan δ (0.25) support accurate power‑loss and thermal budgeting in system designs.
• Production‑Ready Packaging and Compliance: RoHS‑compliant construction and cardboard packing support mass production workflows and environmental requirements.
