LNY2W472MSEG

The LNY2W472MSEG is a screw-terminal aluminum electrolytic capacitor offering 4.7 mF (4700 µF) capacitance at a 450 V rating in a polarized can package. It combines high capacitance and high-voltage capability with a screw-terminal mounting style suited for robust electrical connections.

Designed for general-purpose use and equipment downsizing, this part delivers substantial ripple-handling capacity and a specified 2000-hour endurance at 85°C, making it suitable where sustained high-voltage smoothing and long life under ripple are required.

Key Features

• Capacitance & Rated Voltage — 4700 µF nominal capacitance with a 450 V rated voltage and ±20% tolerance (120 Hz, 20°C).
• High Ripple Current — Low-frequency ripple current of 15.2 A at 120 Hz and high-frequency ripple current of 21.28 A at 10 kHz, specified for handling substantial AC ripple in power circuits.
• Endurance at Elevated Temperature — Load life specified as 2000 hours with rated ripple current at 85°C, with recovery measurements after return to 20°C per the series specification.
• Electrical Loss & Leakage — Tangent of loss angle (tan δ) of 0.25 at 20°C/120 Hz and a typical leakage current up to 4360 µA, with datasheet guidance for leakage limits expressed as 3√CV or 5 mA (whichever is smaller) after 5 minutes at 20°C.
• Polarized Screw-Terminal Package — Radial can with screw terminals for secure, low-resistance connections and mechanical robustness in high-current applications.
• Operating Range — Rated for operation from −40°C to +85°C to cover typical industrial ambient conditions.
• Physical Size & Packing — Dimension L × D: 14.5 × 6.35 cm (φ63.5 × 145 mm) and supplied in cardboard packing for mass-production handling.
• RoHS Compliant — Conforms to RoHS directive as noted in the series documentation.

Typical Applications

• General-purpose power systems — Polarized high-voltage capacitance for smoothing and energy storage in equipment where a 450 V, 4700 µF capacitor is required.
• Equipment downsizing — Higher capacitance in the LNY series supports compact power modules and designs that aim to reduce overall equipment footprint.
• High-ripple power circuits — Suitable for circuits exposed to significant ripple currents, as indicated by 15.2 A (120 Hz) and 21.28 A (10 kHz) ripple ratings.

Unique Advantages

• High-voltage, high-capacitance combination — 4700 µF at 450 V provides substantial energy storage in a single component, reducing the need for multiple lower-voltage capacitors.
• Designed for sustained ripple — Explicit low- and high-frequency ripple current ratings allow selection with confidence in high-stress AC environments.
• Defined high-temperature endurance — 2000-hour load-life specification at 85°C gives a measurable reliability baseline for thermal and ripple loading scenarios.
• Screw-terminal robustness — Screw terminals enable secure electrical and mechanical connections for higher-current and serviceable installations.
• Wide operating temperature — −40°C to +85°C rating supports deployment across a broad range of ambient conditions.
• Regulatory compliance — RoHS conformity supports integration into environmentally regulated product lines.
