LNY2W272MSEGBN

The LNY2W272MSEGBN is a Nichicon LNY series aluminum electrolytic capacitor in a screw-terminal radial can package. It provides 2.7 mF capacitance at a 450 V rating in a screw-terminal form factor designed for general-purpose equipment.

Engineered for higher capacitance and sustained ripple-duty performance, this part is suited for applications that require high-voltage energy storage and robust ripple handling while operating across a −40 °C to 85 °C temperature range.

Key Features

• Capacitance & Voltage — 2.7 mF (2700 µF) rated at 450 V, ±20% tolerance (120 Hz, 20 °C) for high-voltage bulk energy storage.
• Screw Terminal Mounting — Radial can with screw terminals and M5 bolt compatibility (φ63.5 size) for secure, low-resistance connections in power assemblies.
• High Ripple Current — 10.8 A at 120 Hz (low frequency) and 15.12 A at 10 kHz (high frequency) to support heavy ripple and smoothing demands in power supplies.
• Endurance — Load life rated to 2000 hours at 85 °C with rated ripple current applied, ensuring predictable long-term behavior under rated conditions.
• Leakage and Loss — Specified leakage current of 3300 µA and tangent of loss angle (tan δ) 0.25, supporting predictable loss and leakage behavior for design margins.
• Operating Temperature Range — −40 °C to 85 °C for broad environmental compatibility in general-purpose equipment.
• Insulation & Voltage Proof (Series Reference) — Insulation resistance >100 MΩ at DC 500 V between terminal and bracket, and AC 2500 V for 1 minute voltage proof between terminal and bracket (per LNY series specifications).
• RoHS Compliant — Meets RoHS directive requirements as specified for the LNY series.

Typical Applications

• General-purpose power supplies — Bulk smoothing and energy storage at high voltage rails where 450 V rating and high capacitance reduce ripple and voltage fluctuation.
• Industrial power electronics — DC link or filter applications that require sustained ripple current handling and endurance at elevated temperatures.
• Equipment downsizing — High capacitance in the LNY series supports compact power designs by enabling higher stored energy in a single radial can.

Unique Advantages

• High-voltage, high-capacitance combination: 2.7 mF at 450 V provides substantial energy storage in a single component, simplifying power-stage designs.
• Screw-terminal reliability: Robust mechanical and electrical connections for assemblies requiring secure mounting and repeatable torqueable terminations.
• Designed for ripple duty: Specified low- and high-frequency ripple current ratings enable use in heavy-duty smoothing and filtering roles.
• Engineered endurance: 2000-hour load-life rating at 85 °C gives designers a defined reliability baseline for thermal and ripple stress.
• Predictable leakage and loss metrics: Specified leakage current and tan δ support accurate thermal and loss budgeting in power designs.
• Regulatory compliance: RoHS compliance helps meet environmental requirements for commercial and industrial projects.
