LNY2G392MSEHBN

The LNY2G392MSEHBN is a screw‑terminal aluminum electrolytic capacitor designed for general‑purpose power applications requiring high capacitance at elevated voltages. It delivers 3.9 mF capacitance at a 400 V rating in a radial can with screw terminals, offering a durable connection option for high‑current and serviceable installations.

Key value propositions include a broad operating temperature range (−40 °C to +85 °C), specified ripple current capability, a 2000‑hour endurance at 85 °C, and RoHS compliance—combining stable performance, serviceability and regulatory conformity for industrial and equipment designs.

Key Features

• Capacitance & Voltage: 3.9 mF rated capacitance at 400 V, ±20% tolerance (120 Hz, 20 °C), suitable where large bulk storage and high DC voltage are required.
• Screw‑Terminal Mounting: Radial can with screw terminals for secure, serviceable high‑current connections and straightforward panel or bracket mounting.
• Operating Temperature & Endurance: Specified for −40 °C to +85 °C with a load life of 2000 hours at 85 °C under rated ripple conditions.
• Ripple Current Capability: Handles 14.6 A at 120 Hz and 20.44 A at 10 kHz, supporting substantial AC ripple demands in power circuits.
• Loss & Leakage Characteristics: Tangent of loss angle (tanδ) 0.25 and measured leakage current of 3.74 mA, enabling predictable dissipation and end‑of‑life planning.
• Form Factor & Packaging: Size φ76.2 × 85 mm length (L: 8.5 × D: 7.62 cm), supplied in cardboard packing and available in mass production quantities.
• Regulatory Compliance: RoHS compliant to meet applicable environmental directive requirements.

Typical Applications

• General‑Purpose Power Supplies: Bulk energy storage and smoothing at 400 V DC where high capacitance and ripple handling are required.
• Industrial Equipment: Power filtering and decoupling in industrial drives and control systems operating within −40 °C to +85 °C.
• High‑Voltage Power Modules: Support for DC link and intermediate bus circuits that benefit from screw‑terminal robustness and high ripple current capability.

Unique Advantages

• High Voltage Bulk Energy: 400 V rating combined with 3.9 mF capacitance delivers significant bulk energy storage for DC bus and filtering functions.
• Serviceable Screw Terminals: Screw‑terminal package simplifies installation, wiring and replacement without soldering, reducing downtime in maintenance scenarios.
• Designed for Elevated Temperature Operation: 2000‑hour endurance at 85 °C gives predictable lifecycle behavior in warm operating environments.
• Strong Ripple Performance: Specified ripple current at both 120 Hz and 10 kHz supports a range of power conversion topologies and switching frequencies.
• Measured Electrical Parameters: Explicit tanδ (0.25) and leakage current (3.74 mA) values enable accurate thermal and leakage budgeting during design.
• RoHS Compliant: Compliance supports designs that must meet environmental directive requirements.
