LNY2G332MSEFBN

The LNY2G332MSEFBN is a screw‑terminal aluminum electrolytic capacitor from Nichicon's LNY series, offering 3.3 mF capacitance at a 400 V rating. It is designed for general‑purpose power applications that require high capacitance and substantial ripple handling in a radial, screw‑terminal can.

With an operating temperature range of −40°C to 85°C and a specified load life of 2000 hours at 85°C, this part targets compact power systems and equipment downsizing where reliable bulk energy storage and smoothing are required.

Key Features

• Capacitance and Voltage: 3.3 mF (3300 µF) nominal capacitance at a 400 V rated voltage, providing substantial bulk capacitance for high‑voltage power rails.
• Screw‑terminal, radial can package: Robust screw terminal mounting with a φ51 × 145 mm (D × L) can form factor for secure mechanical and electrical connections in power assemblies.
• Ripple current capability: High ripple current ratings—12.4 A at 120 Hz (low frequency) and 17.36 A at 10 kHz (high frequency)—to support heavy ripple and dynamic load conditions.
• Electrical loss and leakage: Specified tangent of loss angle tanδ of 0.25 at 20°C, 120 Hz, and leakage current of 3440 µA for predictable ESR/DF behavior and self‑discharge characteristics.
• Endurance: Rated for 2000 hours of load life at 85°C with applied rated DC voltage plus ripple current, supporting longer service intervals in sealed power units.
• Temperature range: Operates from −40°C to 85°C to accommodate a wide range of industrial and commercial ambient conditions.
• Compliance and packing: RoHS‑compliant material construction; supplied in cardboard packing for bulk production handling.

Typical Applications

• Industrial power supplies: Bulk energy storage and smoothing on 400 V DC rails to reduce voltage ripple and support dynamic loads.
• Commercial power systems: Energy storage and filtering in power conversion equipment and large‑format power modules where high voltage and high capacitance are required.
• Compact power assemblies: Enables equipment downsizing by providing high capacitance in a screw‑terminal radial package for secure mounting in constrained enclosures.

Unique Advantages

• High bulk capacitance: 3.3 mF provides significant energy storage for DC bus smoothing and transient support.
• 400 V rating: Suits high‑voltage power rails and systems that require reliable operation at elevated DC voltages.
• High ripple handling: 12.4 A at 120 Hz and 17.36 A at 10 kHz reduce heating and extend service life under heavy ripple conditions.
• Proven endurance: 2000 hours at 85°C under rated conditions delivers predictable long‑term performance in sealed power units.
• Secure screw‑terminal mounting: Radial can with screw terminals simplifies installation and provides robust electrical connections for high current paths.
• Regulatory compliance: RoHS‑compliant construction supports restricted‑substance requirements for commercial and industrial supply chains.
