LNY2W332MSEG

The LNY2W332MSEG is a screw-terminal aluminum electrolytic capacitor designed for general-purpose high-voltage DC applications. It delivers 3.3 mF (3300 µF) capacitance at a 450 V rating in a radial can with robust screw terminals for secure electrical and mechanical connections.

Engineered for demanding power environments, this capacitor offers high capacitance density, elevated ripple handling, and a specified 2000-hour endurance at 85°C, making it suitable where reliable bulk energy storage and ripple smoothing are required.

Key Features

• Capacitance & Voltage — 3.3 mF (3300 µF) rated at 450 V for high-voltage bulk energy storage and DC smoothing.
• Screw Terminal Mounting — Radial can with screw terminals for secure, low-resistance connections; terminal design accommodates M5 fastening for the φ63.5 size.
• Operating Temperature Range — Rated from –40°C to +85°C for operation across a broad thermal range.
• Load Life / Endurance — 2000 hours at 85°C with rated ripple current applied, providing predictable lifetime performance under sustained load.
• Ripple Current Capability — Rated ripple current of 12 A at 120 Hz and 16.8 A at 10 kHz to address both low- and high-frequency ripple conditions.
• Leakage and Loss Characteristics — Specified leakage current of 3650 µA and a tangent of loss angle (tan δ) of 0.25.
• Tolerance & Polarization — ±20% capacitance tolerance (120 Hz, 20°C) and polarized design for DC applications.
• Form Factor — Physical size φ63.5 × 105L (L: 10.5 cm × D: 6.35 cm) in a radial can package; shipped in cardboard packing for mass production handling.
• RoHS Compliant — Conforms to RoHS directive requirements.

Typical Applications

• High-voltage DC filtering — Bulk smoothing and ripple reduction in DC bus and power supply stages where 450 V rating and high capacitance are required.
• Energy storage for power electronics — Short-term energy buffering and decoupling in converters and inverters that demand high ripple tolerance.
• Industrial power equipment — General-purpose use in industrial controllers and power systems that require durable, long-life capacitors at elevated temperatures.

Unique Advantages

• High-voltage, high-capacitance combination — 3.3 mF at 450 V provides substantial bulk energy in a single component, reducing BOM count for high-voltage designs.
• Robust screw-terminal interface — Screw terminals and M5-compatible fastening deliver reliable electrical contact and secure mounting for vibration-prone environments.
• Defined ripple performance — Separate ripple ratings at 120 Hz and 10 kHz (12 A and 16.8 A) support designs with mixed-frequency ripple content.
• Rated endurance under load — 2000-hour life at 85°C under rated ripple current offers a predictable service profile for long-running systems.
• Wide operating temperature span — –40°C to +85°C rating accommodates installations across varied ambient conditions.
• Compliance and production-ready packaging — RoHS compliance and cardboard packing facilitate regulatory alignment and volume handling.
