LAS2G221MELB30

The LAS2G221MELB30 is an aluminum electrolytic, snap-in terminal capacitor offering 220 µF capacitance at a 400 V rating in a compact φ30 × 30 mm can. Designed for general-purpose power applications, it provides high-voltage capability and elevated-temperature endurance.

Key value propositions include a 105°C operating rating with a qualified 2000-hour life at that temperature, measurable ripple current specifications across frequency, and RoHS compliance for restricted-substance conformity.

Key Features

• Capacitance & Tolerance — 220 µF nominal capacitance with ±20% tolerance at 120 Hz and 20°C, suitable for bulk energy storage and decoupling in high-voltage circuits.
• High Voltage Rating — Rated voltage of 400 V to support high-voltage power rails and DC link applications.
• High-Temperature Endurance — Rated for operation from -25°C to +105°C with a guaranteed endurance of 2000 hours at 105°C when subjected to DC bias plus rated ripple current.
• Loss Characteristics — Tangent of loss angle (tan δ) of 0.20 max at 120 Hz and 20°C for predictable dissipation characteristics.
• Ripple Current Performance — Specified ripple current of 1.24 A at 120 Hz and 1.426 A at 10 kHz, with defined frequency coefficients for ripple-current scaling.
• Snap-In Radial Package — Radial, can-type snap-in terminals (φ30 × 30 mm / L:3 × D:3 cm) for secure mounting and straightforward PCB assembly.
• Safety Vent — Pressure relief vent designed to operate under abnormal voltage conditions to mitigate hazardous failure modes.
• RoHS Compliant — Conforms to RoHS directive (2011/65/EU, (EU)2015/863) for restricted substance requirements.

Typical Applications

• General-purpose power equipment — Bulk capacitance and high-voltage rating provide energy storage and smoothing in general power circuits.
• Voltage-fluctuation environments — Specifically suited for equipment operating in areas with fluctuating voltages due to its improved safety features for abnormal voltages.
• High-temperature systems — Use in designs that require reliable performance at elevated temperatures up to 105°C with a rated 2000-hour operational lifetime.

Unique Advantages

• High-voltage capability: 400 V rating supports high-voltage rails and DC-link requirements without additional series components.
• Validated high-temperature life: 2000 hours at 105°C under rated conditions demonstrates resilience for prolonged elevated-temperature operation.
• Measured ripple specifications: Published ripple currents at 120 Hz and 10 kHz (1.24 A and 1.426 A respectively) let designers size thermal and cooling margins accurately.
• Robust mechanical mounting: Snap-in, radial can package simplifies assembly and provides secure PCB retention for power modules.
• Safety-focused design: Incorporates a pressure relief vent to reduce risk under abnormal voltage stress.
• Regulatory compliance: RoHS conformity supports environmental and supply-chain requirements.
