LNY2W272MSEGBB

The LNY2W272MSEGBB is a screw-terminal aluminum electrolytic capacitor providing 2.7 mF (2700 µF) nominal capacitance at a rated voltage of 450 V. It is a radial can with screw terminals designed for general-purpose, high-voltage DC applications where robust electrical connection and serviceability are required.

Designed for elevated-temperature operation and sustained ripple handling, this capacitor supports -40°C to 85°C operation and a rated lifetime of 2000 hours at 85°C, enabling reliable performance in compact, high-voltage power systems and equipment downsizing efforts.

Key Features

• High nominal capacitance: 2.7 mF (2700 µF) provides substantial bulk energy storage for DC bus smoothing and bulk filtering.
• 450 V rated voltage: Suitable for 450 V systems and applications requiring high-voltage DC handling.
• Screw terminal mounting: Radial can with screw terminals for secure, low-resistance electrical connections and easy field serviceability.
• Elevated temperature life: Rated lifetime of 2000 hours at 85°C, supporting sustained operation under high-temperature stress.
• High ripple current capability: 10,800 mA at 120 Hz (low frequency) and 15,120 mA at 10 kHz (high frequency) to handle significant AC ripple on DC rails.
• Leakage and dissipation: Specified leakage current of up to 3,300 µA and a tangent of loss angle (tan δ) of 0.25 for predictable electrical behavior.
• Wide operating temperature range: Operates from -40°C to 85°C to cover a broad set of industrial environments.
• Physical size and packaging: φ63.5 × 90 mm (D × L) can size, supplied in cardboard packing for mass-production quantities.
• RoHS compliant: Meets RoHS directive requirements for restricted substances.

Typical Applications

• High-voltage DC bus smoothing: Bulk energy storage and voltage stabilization for 450 V DC systems using the capacitor's high capacitance and voltage rating.
• Power supply bulk filtering: Handling significant ripple currents (10.8 A @ 120 Hz and 15.12 A @ 10 kHz) to reduce ripple on DC outputs.
• Industrial equipment downsizing: Compact 2.7 mF in a φ63.5 × 90 mm can supports equipment reduction goals while maintaining performance.
• General-purpose high-voltage applications: Suitable wherever a robust, serviceable screw-terminal capacitor is required in general-purpose designs.

Unique Advantages

• High-voltage capability: 450 V rating enables integration into higher-voltage DC systems without series stacking.
• Robust ripple handling: Specified ripple currents at both low and high frequencies allow predictable thermal and electrical performance under load.
• Serviceable termination: Screw terminals provide a durable electrical connection and simplify assembly and maintenance compared with solder-only terminations.
• Designed for elevated operating stress: 2000-hour endurance at 85°C supports long-term use in warmer operating environments.
• Clear electrical parameters: Defined leakage current (3,300 µA) and tan δ (0.25) make it straightforward to model and validate in system designs.
• Compliance and packaging: RoHS-compliant construction and cardboard packing for production-level logistics.
