LAS2G221MELA35

The LAS2G221MELA35 is a snap-in terminal type aluminum electrolytic capacitor rated 220 µF at 400 V, designed for general-purpose power applications. It delivers high-voltage energy storage and filtering in a compact radial can package with snap-in mounting and tray packing for mass production.

Built for elevated-temperature operation, this capacitor is specified for -25 °C to +105 °C and a 2000-hour endurance at 105 °C, with design features that address ripple handling and safety under abnormal voltage conditions.

Key Features

• High Voltage Rating — 400 V rated voltage suitable for high-voltage DC filtering and energy storage in power circuits.
• Capacitance and Tolerance — 220 µF nominal capacitance with ±20% tolerance at 120 Hz, 20 °C for predictable bulk storage.
• Thermal Endurance — Rated for 2000 hours at 105 °C under DC bias plus rated ripple current, providing sustained performance in hot environments.
• Ripple Current Capability — 1.24 A at 120 Hz and 1.426 A at 10 kHz, with frequency coefficients available for broader frequency performance planning.
• Low Leakage and Loss — Leakage current of 0.88 mA and tan δ ≤ 0.20 (120 Hz, 20 °C) for reduced parasitic losses and predictable behavior after long-term use.
• Snap-In Radial Can Package — φ25 × 35 mm can with snap-in terminals enables secure PCB mounting and efficient assembly in power racks and modules.
• Improved Safety Features — Designed with pressure relief venting and measures for permissible abnormal voltage, suitable for equipment in areas with voltage fluctuation.
• RoHS Compliant & Mass Production Ready — Meets RoHS requirements and is supplied in tray packing for production-scale assembly.

Typical Applications

• General-Purpose Power Electronics — Bulk filtering and energy storage in industrial power supplies and PCB power sections where a 400 V, 220 µF capacitor is required.
• Systems Operating with Voltage Fluctuations — Suited to equipment used in areas with varying supply conditions due to improved safety features for abnormal voltages.
• High-Temperature Installations — Applications requiring sustained performance up to 105 °C and 2000 hours of rated-life endurance.

Unique Advantages

• Long High-Temperature Lifetime: 2000 hours at 105 °C provides design margin for sustained elevated-temperature operation.
• High Ripple Handling: Measured ripple currents (1.24 A at 120 Hz, 1.426 A at 10 kHz) support effective smoothing under varying ripple spectra.
• Safety-Oriented Design: Pressure relief venting and improvements for abnormal voltage help mitigate hazardous failure modes in fluctuating supply environments.
• Compact Snap-In Packaging: φ25 × 35 mm radial can with snap-in terminals simplifies mechanical retention and high-volume PCB assembly.
• Predictable Electrical Characteristics: Specified tan δ and leakage current limits support stable performance verification and quality control.
• Production-Friendly Supply: Tray packing and mass-production status support consistent procurement and assembly planning.
