LGW2G221MELA35

The LGW2G221MELA35 is a snap-in terminal aluminum electrolytic capacitor designed for general-purpose high-voltage applications. It combines a 220 µF capacitance with a 400 V rating in a radial, snap-in can suitable for bulk energy storage, DC link decoupling, and power-supply smoothing.

Engineered for elevated thermal and ripple stress, this capacitor is specified for operation up to 105°C with demonstrated endurance under rated ripple current for 3000 hours, and it is RoHS compliant.

Key Features

• Electrical performance: Rated capacitance 220 µF with ±20% tolerance and a 400 V rated voltage for high-voltage DC applications.
• High ripple capability: Specified ripple current of 1.65 A at 120 Hz and 2.36 A at 50 kHz, enabling effective smoothing under AC ripple across common power frequencies.
• Thermal endurance: Operating temperature range −25 °C to +105 °C and qualified to withstand 3000 hours with D.C. bias plus rated ripple current at 105 °C.
• Reliability characteristics: Endurance limits include capacitance change within ±20%, tan δ within 200% of initial specified value, and leakage current not exceeding the initial specification after endurance testing.
• Leakage & dissipation: Leakage current specified as I ≤ 3√CV (µA) after 5 minutes at 20 °C; tan δ limits are defined for the rated voltage range.
• Package & mounting: Radial, snap-in can package (size approximately 3.5 × 2.5 cm) for secure PCB retention and high-density power assemblies. Maximum seated height is specified in the product data.
• Compliance: RoHS directive compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• High-voltage power supplies: Bulk smoothing and energy storage on 400 V rails where high ripple currents and thermal endurance are required.
• DC bus decoupling: DC link capacitors for inverters and power converters that need sustained ripple capability at elevated temperatures.
• Industrial power electronics: Filtering and transient buffering in industrial equipment designed for continuous operation up to 105 °C.
• General-purpose electronic equipment: Wherever a high-voltage, high-ripple-capacity electrolytic capacitor is needed for reliable long-term operation.

Unique Advantages

• High ripple endurance: Rated ripple current specifications at both 120 Hz and 50 kHz provide clear performance expectations across low and high ripple frequencies.
• Long-term thermal reliability: Endurance proven for 3000 hours at 105 °C under rated ripple current, supporting designs requiring elevated temperature operation.
• Secure, easy mounting: Snap-in terminal construction offers robust mechanical retention for high-vibration or densely packed PCBs.
• Clear reliability metrics: Defined limits for capacitance change, tan δ, and leakage current after endurance testing make design margining straightforward.
• Regulatory compliance: RoHS compliance supports environmentally constrained designs and supply-chain requirements.
• Compact high-voltage form factor: 220 µF at 400 V in a radial snap-in can enables space-efficient implementation on high-voltage boards.
