LNY2G392MSEGBB

The LNY2G392MSEGBB is an aluminum electrolytic capacitor in a screw-terminal can designed for general-purpose applications that require high capacitance and reliable high-voltage performance. As a screw terminal type in the LNY series, it provides a high-capacitance solution (3.9 mF at 400 V) in a compact radial can intended to support equipment downsizing and robust power-handling needs.

Key value propositions include high ripple-current capability, a rated operating range from −40 °C to 85 °C, and a demonstrated load life of 2000 hours at 85 °C under rated ripple current.

Key Features

• High Capacitance / Voltage: 3.9 mF (3900 µF) rated at 400 V, providing bulk energy storage for high-voltage applications.
• Screw Terminal Mounting: Radial can with screw terminals (M5 nominal bolt for φ63.5) for secure mechanical and electrical connections in serviceable installations.
• High Ripple Current Handling: Low-frequency ripple current 14.2 A (120 Hz) and high-frequency ripple current 19.88 A (10 kHz), enabling sustained ripple handling under load.
• Endurance / Life: Rated for 2000 hours of ripple-current-applied operation at 85 °C, with specifications verified after recovery to 20 °C.
• Operating Temperature Range: −40 °C to 85 °C, suitable for a broad range of environmental conditions.
• Electrical Loss and Leakage: tan δ = 0.25 (measurement at 20 °C, 120 Hz) and specified leakage current (reported 3740 µA), allowing designers to evaluate ESR-related heating and insulation needs.
• RoHS Compliant: Meets RoHS directive requirements as stated in the LNY series documentation.
• Compact Can Dimensions: Body dimensions: φ63.5 × 105 mm (approx. 10.5 × 6.35 cm), enabling higher capacitance in a screw-terminal radial can format.

Typical Applications

• General-purpose industrial equipment: Provides high-voltage bulk capacitance for systems where reliable energy storage and ripple handling are required.
• High-voltage DC systems: 400 V rating and specified ripple currents make this capacitor suitable for DC link and smoothing roles in high-voltage circuits.
• Equipment downsizing initiatives: The LNY series is described as suited for equipment downsizing, offering higher capacitance density in a screw-terminal can.

Unique Advantages

• High-voltage, high-capacitance combination: Delivers 3.9 mF at 400 V to address bulk energy-storage needs without multiple parallel parts.
• Robust ripple capability: Specified ripple currents at both 120 Hz and 10 kHz reduce the need for oversized capacitor banks to handle dynamic loads.
• Serviceable screw-terminals: Screw-terminal construction facilitates secure connections and easier replacement or maintenance in the field.
• Proven endurance at elevated temperature: 2000-hour load-life rating at 85 °C under rated ripple current provides predictable long-term behavior for thermal-stressed designs.
• Wide ambient range: −40 °C to 85 °C operating range supports deployment across varied environments.
• Regulatory compliance: RoHS compliance supports environmentally conscious design requirements.
