LNY2V392MSEG

The LNY2V392MSEG is a screw-terminal aluminum electrolytic capacitor offering 3.9 mF capacitance at a 350 V rating in a radial can package. Engineered for general-purpose equipment where higher capacitance and robust screw-terminal connections are required, it supports equipment downsizing while providing reliable bulk energy storage and filtering.

Key attributes include a −40°C to 85°C operating range, a rated endurance of 2000 hours at 85°C under ripple load, and RoHS compliance, making it suitable for a wide range of industrial and electronic power-system designs that need high-voltage, high-capacitance smoothing in a screw-terminal form factor.

Key Features

• High Capacitance / High Voltage — 3.9 mF (3900 µF) rated at 350 V for substantial bulk energy storage and smoothing in high-voltage rails.
• Screw Terminal Mounting — Radial can with screw terminals (M5 nominal bolt) for secure, low-impedance connections in power assemblies.
• Thermal and Endurance Rating — Rated operating temperature −40°C to 85°C with a specified life of 2000 hours at 85°C under rated ripple conditions.
• Ripple Current Capability — Low-frequency ripple current 14.10 A at 120 Hz and high-frequency ripple current 19.74 A at 10 kHz to support demanding AC ripple environments.
• Electrical Loss and Leakage — Dissipation factor (tanδ) 0.25 measured at 20°C, 120 Hz, and leakage current specified at 3500 µA after voltage application.
• Mechanical Footprint — Compact radial can: diameter φ63.5 mm × length 80 mm (size dimension L: 8 cm × D: 6.35 cm) suitable for equipment downsizing where space is constrained.
• Compliance — RoHS compliant per product information.

Typical Applications

• General Purpose Equipment — Provides bulk filtering and energy storage for general-purpose power systems that require a high-capacitance, high-voltage screw-terminal capacitor.
• Power Supply Smoothing — Used where 350 V rating and 3.9 mF capacitance are needed to smooth DC rails and absorb ripple currents up to specified levels.
• Industrial Electronics — Suited for industrial assemblies that benefit from screw-terminal mounting and robust mechanical connection for high-current ripple conditions.

Unique Advantages

• High-voltage bulk capacitance: 3.9 mF at 350 V gives designers significant energy storage in a single component to reduce system-level component count.
• Robust screw-terminal interface: M5-compatible screw terminals deliver secure electrical and mechanical connections for high-current applications.
• Designed for compact systems: φ63.5 mm × 80 mm can footprint helps with equipment downsizing while retaining high capacitance.
• Rated ripple endurance: Specified ripple currents at 120 Hz and 10 kHz with a 2000-hour life at 85°C provide predictable performance under sustained load.
• Measured electrical characteristics: Defined tanδ (0.25 at 20°C, 120 Hz) and specified leakage current allow accurate design margin calculations.
• Regulatory compliance: RoHS status ensures suitability for designs requiring restricted-substance compliance.
