LGA2W271MELB30

The LGA2W271MELB30 is a snap-in, radial aluminum electrolytic capacitor engineered for high-capacitance, high-ripple-current applications. It combines a 270 µF capacitance with a 450 V rated voltage and is built for long-life performance at elevated temperatures.

Designed for general-purpose electronic equipment, this component targets designs that require sustained ripple endurance and reliable operation up to 105°C while meeting RoHS environmental requirements.

Key Features

• Capacitance & Voltage — 270 µF rated capacitance at 450 V for energy storage and bulk filtering in high-voltage circuits.
• High Ripple Current & Endurance — Rated ripple current of 1.9 A at 120 Hz (1.900 A / 1900 mArms) and 2.717 A at 50 kHz, with endurance specified as 5000 hours at 105°C under rated ripple and DC bias.
• Temperature Range & Reliability — Operating temperature range from -40°C to +105°C; endurance and post-test limits are defined (capacitance change within ±20%, tan δ ≤ 200% of initial, leakage ≤ initial specified value after 5000 h at 105°C).
• Package & Mounting — Radial, can-type snap-in package (30 × 30 mm footprint; seated height up to 1.181 inch) for secure PCB retention and straightforward assembly.
• Electrical Characteristics — Equivalent series resistance (ESR) ~200 mΩ at 120 Hz; capacitance tolerance ±20%.
• RoHS Compliance — Conforms to RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General-Purpose Electronic Systems — Suited for equipment that requires a 270 µF, 450 V capacitor with high ripple endurance and long operational life at elevated temperatures.
• High-Voltage Bulk Storage — Provides high-capacitance bulk energy storage where sustained ripple handling and long-term stability at 105°C are required.
• Power Conditioning — Appropriate for circuits needing robust ripple current capability and controlled ESR at 120 Hz.

Unique Advantages

• Proven Long-Life Rating — 5000 hours endurance at 105°C under rated ripple current gives designers defined lifetime performance parameters for thermal stress conditions.
• High Ripple Handling — Rated ripple currents of 1.9 A (120 Hz) and 2.717 A (50 kHz) enable reliable operation in high-stress ripple environments.
• High Voltage Capability — 450 V rating supports higher-voltage circuits without stacking or series configurations.
• Robust Mounting — Snap-in radial can provides firm board retention for assemblies subject to vibration or handling.
• Engineered Electrical Performance — ESR specified at 200 mΩ (120 Hz) and defined leakage characteristics provide predictable behavior for power design and simulation.
• RoHS Compliant — Meets current RoHS requirements for environmental conformity.
