LNY2G122MSEFBB

The LNY2G122MSEFBB is an aluminum electrolytic capacitor from Nichicon's LNY series featuring a screw-terminal radial can design. It provides 1.2 mF capacitance at a 400 V rating with a polarized configuration and is intended for general-purpose high-voltage applications.

Designed for higher capacitance in compact packages, this screw-terminal part supports equipment downsizing while delivering specified ripple handling and a 2000-hour load life at 85°C.

Key Features

• Electrical Performance 1.2 mF nominal capacitance at 400 V rated voltage with ±20% tolerance (120 Hz, 20°C); polarized configuration for DC applications.
• Ripple Current Capability Rated ripple current: 7.10 A at 120 Hz (low frequency) and 9.94 A at 100 kHz (high frequency), supporting demanding ripple conditions.
• Leakage Current Specified leakage current of 2070 µA.
• Reliability & Endurance Load life: 2000 hours at 85°C with rated ripple current applied; designed to meet the LNY series endurance criteria.
• Mechanical / Package Screw terminal, radial can package with nominal dimensions: diameter 51 mm and length 65 mm (L: 6.5 × D: 5.1 cm); terminal hardware compatible with M5 bolts for secure mounting.
• Operating Temperature Specified operating range from −40°C to +85°C.
• Regulatory RoHS compliant.

Typical Applications

• High-voltage power supplies — Bulk smoothing and filtering where 400 V rated capacitance is required and high ripple current capability improves thermal and electrical performance.
• Power conversion equipment — Energy storage and ripple handling in compact power modules that benefit from the screw-terminal, high-capacitance LNY package.
• Industrial systems — General-purpose high-voltage circuits in industrial equipment that require robust endurance at elevated temperatures (2000 h at 85°C).

Unique Advantages

• High-voltage, high-capacitance combination: 400 V rating with 1.2 mF capacitance provides substantial energy storage in a compact radial can.
• Strong ripple handling: 7.10 A (120 Hz) and 9.94 A (100 kHz) ripple ratings support designs with significant AC superimposed on DC bus voltages.
• Screw-terminal robustness: Screw-terminal mounting and M5-compatible bolt seating ensure secure electrical and mechanical connections for high-current applications.
• Designed for compact systems: LNY series emphasis on higher capacitance supports equipment downsizing without sacrificing endurance.
• Wide operating range and endurance: −40°C to +85°C operating range with a 2000-hour rated life at 85°C provides predictable performance in elevated-temperature environments.
• RoHS compliant: Meets environmental regulatory requirements for lead-free materials.
