LNY2W272MSEFBB

The LNY2W272MSEFBB is a screw‑terminal, large‑can aluminum electrolytic capacitor in Nichicon’s LNY series, offering 2.7 mF (2700 µF) capacitance at a 450 V rating. It is designed for general‑purpose applications that require high bulk capacitance and high‑voltage capability in a screw‑terminal radial can package.

Key value propositions include a high voltage rating, substantial ripple current capability at both low and high frequencies, and a rated load life of 2000 hours at 85°C—features that support equipment downsizing and reliable power storage in general‑purpose power systems.

Key Features

• Capacitance & Tolerance: 2.7 mF (2700 µF) with tolerance of −20% to +20% (measured at 120 Hz, 20°C).
• Rated Voltage: 450 V DC rating suitable for high‑voltage bulk and filtering applications.
• Ripple Current Performance: Low‑frequency ripple current 10.3 A at 120 Hz and high‑frequency ripple current 14.42 A at 10 kHz, providing robust acceptance of AC ripple across common power frequencies.
• Loss Characteristics: Tangent of loss angle (tan δ) = 0.25 (measured at 20°C, 120 Hz), enabling predictable dissipation behavior in design calculations.
• Leakage Current: Specified leakage current of 3300 µA provides a defined baseline for standby and charged‑state behavior.
• Endurance & Temperature Range: Rated life of 2000 hours at 85°C; operating temperature range −40°C to +85°C.
• Package & Mounting: Radial can with screw terminals (M5 nominal bolt for φ51 case), secure mechanical and electrical termination for high‑current applications.
• Physical Size & Packaging: Size φ51 × 145 mm (L: 14.5 × D: 5.1 cm); supplied in cardboard packing. Product status: Mass Production.
• Environmental Compliance: RoHS compliant.

Typical Applications

• General‑purpose power systems: Use where a 450 V, 2700 µF screw‑terminal capacitor is required for bulk energy storage or filtering in general applications.
• High‑voltage DC filtering: Suitable for circuits that need polarized, high‑voltage aluminum electrolytic capacitors with robust ripple handling.
• Equipment designs targeting downsizing: The LNY series’ higher capacitance in a large‑can screw‑terminal format supports reductions in component count or overall system volume.

Unique Advantages

• High voltage and large capacitance: 450 V rating combined with 2.7 mF capacitance delivers substantial bulk energy storage in a single component.
• Clear ripple specifications: Defined low‑ and high‑frequency ripple current ratings (10.3 A at 120 Hz, 14.42 A at 10 kHz) let engineers size cooling and thermal margins accurately.
• Durability at elevated temperature: 2000 hours rated life at 85°C provides predictable end‑of‑life expectations for high‑temperature applications.
• Screw‑terminal robustness: Radial can with screw terminals and M5 nominal bolt mounting supports secure electrical connections and mechanical retention under high current.
• Measured electrical characteristics: Specified tan δ (0.25 at 20°C, 120 Hz) and leakage current (3300 µA) allow straightforward integration into loss and leakage budgets.
• RoHS compliant and production ready: Meets RoHS requirements and is available in mass production quantities with standard cardboard packing.
