LGX2E271MELZ25

The LGX2E271MELZ25 is a snap‑in terminal aluminum electrolytic capacitor designed for high‑temperature, long‑life power applications. It delivers 270 µF at a rated voltage of 250 V in a compact radial can snap‑in package and is polarized for DC circuits.

Engineered for rectifier circuits in general inverters and switching power supplies, this capacitor combines 105°C endurance with defined ripple handling and RoHS compliance for reliable performance in demanding power electronics environments.

Key Features

• Snap‑in Terminal Package Radial can snap‑in mounting simplifies board installation and mechanical retention for power modules and filter banks.
• High Voltage / Capacitance 270 µF rated capacitance at 250 V suited for bulk filtering and energy storage in rectifier and power conversion stages.
• 105°C Long‑Life Endurance Designed to withstand 5000 hours of rated ripple current at 105°C; after endurance testing capacitance change remains within ±20% and leakage current meets initial specification.
• Ripple Current Capability Specified ripple handling of 1.01 A at 120 Hz and 1.515 A at 50 kHz for use in both low‑ and high‑frequency power circuits.
• Wide Operating Temperature Rated for operation from −25°C to +105°C with low‑temperature impedance stability (Z(−25°C)/Z(+20°C) ≤ 4 for 200–250 V range).
• Leakage and Loss Characteristics Leakage current conforms to I ≤ 3√CV (µA) after 5 minutes at 20°C; tangent of loss angle (tan δ) maximum 0.15 for the 200–400 V range at 120 Hz, 20°C.
• RoHS Compliant Meets RoHS directive (2011/65/EU, (EU)2015/863) requirements for restricted substances.
• Compact Footprint Size approximately 2.5 × 2.2 cm (L × D), providing a smaller‑sized option for space‑constrained power designs.

Typical Applications

• Switching Power Supplies Bulk filtering and smoothing on the DC bus where 250 V rating and high ripple capability reduce voltage ripple and improve regulator stability.
• Inverter Rectifier Stages Energy storage and ripple attenuation for rectifier circuits in general inverter designs.
• Industrial Power Modules Long‑life 105°C endurance supports reliability requirements in industrial converters and power distribution units.

Unique Advantages

• Long‑Term High‑Temperature Reliability: 5000‑hour endurance at 105°C gives clear, verifiable assurance for extended operation under thermal stress.
• Defined Ripple Performance: Specified ripple currents at both 120 Hz and 50 kHz enable design confidence across low and high switching frequencies.
• Quantified Electrical Limits: Leakage current formula (I ≤ 3√CV) and tan δ limits provide measurable acceptance criteria for production and validation testing.
• Compact, Mechanically Robust Mounting: Snap‑in radial can construction simplifies assembly while maintaining secure board retention in power assemblies.
• Regulatory Clarity: RoHS compliance supports use in regulated markets without additional material qualification steps.
