LNT2H272MSEGBN

The LNT2H272MSEGBN is a screw‑terminal aluminum electrolytic capacitor in Nichicon’s LNT series, specified for high‑voltage, high‑ripple applications. It provides 2.7 mF capacitance at a 500 V rated voltage, with 105°C standard temperature rating and polarized screw‑terminal mounting for secure, low‑impedance connections.

Designed for general‑purpose power electronics where bulk energy storage and high ripple handling are required, this part is suitable for systems that demand robust thermal endurance and board‑level mounting flexibility.

Key Features

• High voltage rating: 500 V rated voltage suitable for high‑voltage power rails and DC link applications.
• Large capacitance: 2.7 mF (2700 µF) provides substantial bulk energy storage for filtering and smoothing tasks.
• High ripple current capability: Rated ripple current of 11 A at 120 Hz and 15.4 A at 100 kHz to support high‑frequency and low‑frequency ripple conditions.
• Elevated operating temperature: 105°C standard rating with a specified lifetime of 2000 hours at 105°C under rated ripple and DC bias (applicable for this voltage range).
• Mechanical and mounting: Screw terminal, radial can package (φ63.5 × 150L) for secure bolted connections and easy replacement or field service.
• Electrical reliability: Capacitance tolerance ±20% (measured at 120 Hz, 20°C), tanδ 0.20 (max), and specified leakage current of 3480 µA.
• Environmental compliance: RoHS compliant.
• Packaging: Supplied in cardboard packing for bulk handling and storage.

Typical Applications

• Industrial power supplies: Bulk smoothing and energy buffering on high‑voltage DC rails to stabilize supply for converters and controllers.
• Inverters and motor drives: DC link smoothing and ripple suppression where high voltage and elevated ripple current capability are required.
• Uninterruptible power supplies (UPS) and energy storage: Bulk capacitance for hold‑up time and transient absorption in medium‑to‑high voltage systems.
• Power conversion systems: Filtering and decoupling in high‑voltage converter stacks and renewable energy electronics where secure screw‑terminal connections are preferred.

Unique Advantages

• High‑voltage, high‑capacitance combination: 500 V and 2.7 mF provide a compact option for large energy storage on high‑voltage rails.
• Robust ripple handling: Dual ripple current ratings at 120 Hz and 100 kHz support both mains‑frequency and high‑frequency converter applications.
• Screw‑terminal reliability: Bolted terminals enable low‑impedance, secure connections ideal for serviceable industrial equipment.
• Thermal endurance: 2000‑hour life at 105°C under rated conditions gives predictable ageing characteristics in elevated temperature installations.
• Clear electrical specifications: Defined tanδ, leakage current, and tolerance values simplify design margins and qualification testing.
• Regulatory compliance: RoHS‑compliant construction supports environmental requirements for electronics assemblies.
