LNY2W392MSEGBB

The LNY2W392MSEGBB is a screw‑terminal aluminum electrolytic capacitor in Nichicon’s LNY series, offering 3.9 mF (3900 µF) capacitance at a 450 V rating. Engineered for general‑purpose applications, it delivers high capacitance and voltage in a radial can with screw terminals for robust electrical and mechanical connections.

Key value comes from its high rated voltage, elevated ripple capability, and an endurance specification of 2000 hours at 85°C—making it suitable for designs that require compact high‑voltage bulk capacitance and reliable long‑term operation. The part is RoHS compliant and supplied in cardboard packing for mass production.

Key Features

• Capacitance & Voltage — Rated at 3.9 mF (3900 µF) with a 450 V working voltage and ±20% capacitance tolerance (120 Hz, 20°C).
• Screw Terminal Mounting — Radial can with screw terminals and M5 nominal bolt compatibility for secure, low‑impedance connections and easy installation.
• High Ripple Current Handling — Specified ripple capability of 13.5 A at 120 Hz and 18.9 A at 10 kHz to support demanding ripple conditions within the rated limits.
• Endurance & Temperature Range — Load life of 2000 hours at 85°C; specified operating temperature range from −40°C to +85°C.
• Leakage and Loss Characteristics — Leakage current specified at 3970 µA and tangent of loss angle (tan δ) of 0.25, supporting predictable loss and leakage behavior under rated conditions.
• Form Factor — Physical dimensions φ63.5 × 125 mm (D: 6.35 cm × L: 12.5 cm); cardboard packing for mass production handling.
• Compliance — RoHS compliant.

Typical Applications

• General Purpose — Intended for general‑purpose circuits that require high capacitance at elevated voltage ratings.
• Equipment Downsizing — Suited for applications where higher capacitance in a compact screw‑terminal can supports reduced system footprint.
• High‑Voltage Circuitry — Applicable where components must operate up to a 450 V rated voltage within the specified temperature and endurance limits.

Unique Advantages

• High Voltage + High Capacitance: 3.9 mF at 450 V provides substantial bulk capacitance for high‑voltage designs, reducing the need for paralleling multiple smaller parts.
