LNY2W122MSEFBB

The LNY2W122MSEFBB is a screw-terminal aluminum electrolytic capacitor from Nichicon’s LNY series, offering 1,200 µF capacitance at a 450 V rating. Designed for general-purpose power applications, it combines high capacitance in a compact can-style package with robust ripple-current capability and extended endurance.

Key value propositions include high ripple-current handling (6.0 A at 120 Hz and 8.4 A at 10 kHz), a rated operating range from −40 °C to 85 °C, and a guaranteed load life of 2,000 hours at 85 °C—features that support equipment downsizing and reliable performance in demanding power circuits.

Key Features

• Capacitance & Voltage — 1,200 µF nominal capacitance with a rated voltage of 450 V and tolerance of −20% to +20% (120 Hz, 20 °C).
• High Ripple-Current Handling — Low-frequency ripple current 6.0 A at 120 Hz and high-frequency ripple current 8.4 A at 10 kHz, enabling effective smoothing under high AC stress.
• Endurance & Temperature — Load life of 2,000 hours at 85 °C with an operating temperature range of −40 °C to 85 °C.
• Loss Characteristics — Tangent of loss angle (tan δ) of 0.25 measured at 20 °C and 120 Hz for predictable dissipation behavior.
• Leakage & Insulation — Specified leakage current of 2,200 µA (measurement at 20 °C) and insulation resistance performance per series specifications.
• Screw-Terminal Package — Radial can with screw terminals (M5 bolt nominal on φ51 size) for secure, low-impedance connections in power assemblies; package size φ51 × 75L (D: 5.1 cm × L: 7.5 cm).
• Compliance & Packaging — RoHS compliant and supplied in cardboard packing; status: mass production.

Typical Applications

• General-purpose power filtering — Bulk smoothing and decoupling in equipment that requires high-voltage, high-capacitance filtering with reliable ripple-current endurance.
• Equipment downsizing — High capacitance in the LNY form factor supports smaller power assemblies where board space and component consolidation matter.
• Screw-terminal power modules — Direct screw-terminal mounting for secure connections in modular power supplies and assemblies.

Unique Advantages

• High-voltage capability: 450 V rating supports higher-voltage power rails without series stacking.
• Robust ripple performance: 6.0 A (120 Hz) and 8.4 A (10 kHz) ripple ratings reduce thermal stress and extend service life in AC-loaded circuits.
• Designed for endurance: 2,000 hours at 85 °C ensures predictable long-term behavior under rated ripple and voltage conditions.
• Easy, reliable termination: Screw terminals provide a low-impedance, mechanically secure connection for high-current paths.
• Compact high-capacitance form factor: φ51 × 75L packaging delivers 1,200 µF in a size suitable for tighter equipment layouts.
• Regulatory compliance: RoHS-compliant construction supports environmentally conscious designs and supply requirements.
