LHX2W271MELB35

The LHX2W271MELB35 is a snap‑in terminal aluminum electrolytic capacitor designed for high‑voltage, high‑temperature applications. It provides 270 µF capacitance at a 450 V rating in a radial, can snap‑in package optimized for equipment that requires sustained operation up to 125°C.

Built as a long‑life member of Nichicon's LHX/LHT family, this capacitor targets general‑purpose power applications where elevated operating temperature, rated ripple handling and reliable bulk energy storage are required.

Key Features

• Capacitance & Voltage: 270 µF rated capacitance at 450 V, suitable for high‑voltage bulk smoothing and energy storage.
• High‑Temperature Long Life: Rated for operation from –40°C to +125°C with an endurance rating of 5000 hours at 125°C under DC bias plus rated ripple current.
• Snap‑In, Radial Can Package: Snap‑in terminal mounting for secure board attachment in through‑hole power assemblies; package size: φ30 × 35 mm (L: 3.5 × D: 3 cm).
• Ripple Current Capability: Rated ripple 1.27 A (1270 mArms) at 120 Hz, 125°C; higher frequency performance specified (1.816 A at 50 kHz) and frequency coefficients provided for scaling ripple limits.
• Leakage & Dissipation: Leakage current specified by I ≤ 3√CV (μA) after 5 minutes at 20°C; tan δ ≤ 0.20 at 120 Hz, 20°C for predictable loss behavior.
• Tolerance and Polarization: ±20% capacitance tolerance at 120 Hz, 20°C; polarized electrolytic construction for DC applications.
• Environmental Compliance: RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Power Supplies: Bulk smoothing and filtering in high‑voltage supplies operating at elevated temperatures up to 125°C.
• Power Conversion Systems: Energy storage and ripple damping for DC bus circuits in converters and inverters requiring 450 V class components.
• High‑Temperature Equipment: Use in equipment and assemblies where long life at elevated ambient temperatures is required.

Unique Advantages

• High Voltage Support: 450 V rating enables use in higher‑voltage DC systems without series stacking.
• Designed for Elevated Temperatures: 125°C operating rating and 5000‑hour endurance at that temperature provide predictable life in hot environments.
• Robust Ripple Handling: Rated ripple current of 1.27 A at 120 Hz (125°C) with specified frequency coefficients supports accurate thermal and ripple design.
• Secure Snap‑In Mounting: Radial snap‑in terminals facilitate reliable mechanical retention in through‑hole assemblies.
• Measured Loss & Leakage Limits: Specified tan δ and leakage current formula enable predictable electrical loss and self‑discharge behavior in designs.
• Regulatory Compliance: RoHS conformity supports use in designs requiring restricted‑substance compliance.
