LNY2G392MSEHBB

The LNY2G392MSEHBB is an aluminum electrolytic capacitor in a screw‑terminal radial can designed for general-purpose electronic equipment. It provides 3.9 mF nominal capacitance at a 400 V rating with a compact high‑capacitance profile (φ76.2 × 85 mm) and is suited for equipment downsizing where a high-voltage, high-capacitance component is required.

Key reliability and performance characteristics include a rated operating temperature range of −40°C to +85°C, a load life of 2000 hours at 85°C under rated ripple current, RoHS compliance, and packaged in cardboard for transit and storage.

Key Features

• Capacitance & Voltage — 3.9 mF (3900 µF) nominal capacitance with a 400 V rated voltage and ±20% tolerance (120 Hz, 20°C).
• Low-frequency and high-frequency ripple handling — Rated ripple current of 14.6 A at 120 Hz and 20.44 A at 10 kHz supports AC ripple dissipation across a wide frequency range.
• Screw‑terminal radial can — Screw terminal mounting and radial can package provide secure, low‑impedance connections for high-current applications.
• Thermal and life endurance — Designed for a 2000‑hour load life at 85°C with rated ripple current applied; operating temperature range −40°C to +85°C.
• Electrical characteristics — Tangent of loss angle (tan δ) nominally 0.25 and measured leakage current of 3.74 mA; insulation resistance greater than 100 MΩ at DC 500 V between terminal and bracket per series specification.
• High voltage isolation test — Withstands AC 2500 V for 1 minute between terminal and bracket as defined by the series datasheet.
• Packaging & regulatory — Supplied in cardboard packing and compliant with RoHS (2011/65/EU, (EU)2015/863).

Typical Applications

• General-purpose electronic equipment — Provides high-capacitance, high-voltage energy storage for a range of general-purpose designs that require a robust electrolytic solution.
• Equipment downsizing — Suited for designs targeting reduced footprint while maintaining high capacitance and voltage capability, as called out in the LNY series description.
• Screw-terminal mounting systems — Ideal where secure, low‑impedance screw-terminal connections are needed for power assemblies or modules.

Unique Advantages

• High stored energy at elevated voltage — 3.9 mF at 400 V provides substantial energy density for high-voltage applications within a compact can (φ76.2 × 85 mm).
• Robust ripple performance — Specified ripple currents of 14.6 A (120 Hz) and 20.44 A (10 kHz) help manage AC loading across common power frequencies.
• Thermal endurance — Rated for 2000 hours of operation at 85°C under rated ripple current, supporting sustained performance in elevated-temperature environments.
• Secure mechanical and electrical connection — Screw terminal radial can simplifies assembly and provides reliable termination for higher-current paths.
• Series-level safety and isolation — Insulation resistance >100 MΩ at DC 500 V and an AC 2500 V, 1‑minute voltage proof test between terminal and bracket as specified in the series datasheet.
• Regulatory compliance — RoHS compliant to applicable directives, simplifying environmental qualification.
