LAS2G221MELA35ZB

The LAS2G221MELA35ZB is a snap-in terminal aluminum electrolytic capacitor designed for general-purpose power applications. It combines a compact snap-in can package with high-temperature endurance and enhanced safety features to address equipment operating in areas with voltage fluctuation.

Key value comes from its 400 V rating, 220 µF capacitance, and 105°C endurance (with 2000 hours rated ripple current operation), providing reliable bulk energy storage and ripple handling in compact assemblies while meeting RoHS requirements.

Key Features

• Capacitance & Voltage — 220 µF nominal capacitance with a 400 V rated voltage and ±20% capacitance tolerance (measured at 120 Hz, 20°C).
• High-Temperature Endurance — Rated for operation from −25°C to +105°C with specified endurance of 2000 hours at 105°C under DC bias plus rated ripple current.
• Ripple Current Performance — Rated ripple current of 1.24 A at 120 Hz and 1.426 A at 10 kHz, with frequency coefficients provided for higher frequency operation.
• Safety & Abnormal Voltage Protection — Improved safety features for abnormally excessive voltage and a pressure relief vent designed to operate without dangerous conditions such as flames or dispersion of parts.
• Snap-in, Radial Can Package — Snap-in terminal, radial can construction for secure board mounting and compact installation; physical dimensions L: 3.5 × D: 2.5 cm for space-conscious designs.
• Leakage and Loss Characteristics — Leakage current and tan δ specified in the datasheet (leakage measured after 5 minutes at rated voltage, 20°C), enabling predictable performance verification.
• RoHS Compliant — Conforms to the RoHS directive (2011/65/EU, (EU)2015/863) for restricted substances.

Typical Applications

• Power supply filtering in fluctuating-voltage environments — Bulk smoothing and ripple reduction where line voltage can vary; suited to equipment deployed in areas with voltage fluctuation.
• General-purpose electronics — Energy storage and decoupling in assemblies that require a compact, high-voltage electrolytic solution.
• Industrial equipment power systems — Where high-temperature endurance and enhanced safety under abnormal voltage are priorities for long-term reliability.

Unique Advantages

• Compact footprint with high energy density: Smaller case sizes compared to previous series while maintaining 220 µF at 400 V, enabling space savings on the PCB.
• High-temperature reliability: 2000 hours endurance at 105°C under rated ripple current supports sustained operation in hot operating environments.
• Strong ripple handling across frequency: Specified ripple current at both 120 Hz and 10 kHz with frequency coefficients to guide design for different operating frequencies.
• Built-in abnormal-voltage protection: Enhanced safety design and a pressure relief vent reduce risk during over-voltage events without creating hazardous conditions.
• Predictable electrical limits: Clear specifications for capacitance tolerance, leakage current behavior, and tan δ support deterministic design and verification activities.
• Regulatory compliance: RoHS conformity simplifies environmental compliance for finished products.
