LAS2W221MELB35ZB

The LAS2W221MELB35ZB is a snap‑in terminal aluminum electrolytic capacitor designed for general‑purpose power applications. It combines a high 450 V rated voltage with 220 µF capacitance in a compact can-style snap‑in package suitable for assemblies exposed to fluctuating voltages.

Key value comes from high ripple current capability, long endurance at elevated temperature, and integrated safety measures that address abnormal overvoltage conditions while remaining RoHS compliant.

Key Features

• Capacitance & Voltage — 220 µF nominal capacitance rated at 450 V to support high‑voltage DC bus and power filtering applications.
• High‑temperature Endurance — Specified for 2000 hours at 105°C under rated ripple current, providing predictable life performance in hot operating environments.
• Ripple Current Performance — Low‑frequency ripple current of 1.3 A at 120 Hz and high‑frequency ripple current of 1.495 A at 10 kHz to handle demanding ripple loads across common power frequencies.
• Electrical Losses — Tangent of loss angle (tan δ) 0.20 max at 20°C, 120 Hz for controlled dissipation characteristics.
• Leakage Current — Typical leakage current specified as 940 µA, useful for estimating standby and start‑up currents.
• Robust Temperature Range — Rated for operation from −25°C to +105°C to cover a wide range of industrial ambient conditions.
• Snap‑in Mounting — Radial, can‑style snap‑in package (φ30 × 35L) for reliable mechanical retention in power assemblies and simplified board insertion.
• Safety Features — Designed with improved safety for abnormally excessive voltage and a pressure relief vent that operates under abnormal conditions to reduce risk of hazardous failure modes.
• Compliance & Packaging — RoHS compliant and supplied in tray packing for production handling.

Typical Applications

• Power supplies and DC buses — Bulk energy storage and smoothing on high‑voltage DC rails where 450 V rating and 220 µF capacitance are required.
• Industrial equipment — Filtering and ripple management in equipment subject to voltage fluctuations, leveraging the capacitor’s high ripple current and 105°C endurance.
• Power conversion modules — Input/output filtering in rectifiers and converters that require high voltage endurance and reliable long‑term performance.

Unique Advantages

• High‑voltage capability: 450 V rating enables use on higher‑voltage DC buses without additional series components.
• Designed for sustained high‑temperature duty: 2000 hours at 105°C under rated ripple current supports durability in elevated ambient environments.
• Strong ripple handling across frequencies: Rated ripple currents at 120 Hz and 10 kHz allow the part to address both mains and switching ripple conditions.
• Compact snap‑in form factor: φ30 × 35L can size delivers a smaller footprint while maintaining high ripple capability compared with larger cans.
• Built‑in safety behavior: Pressure relief vent and abnormal voltage design reduce the likelihood of dangerous failure modes during overvoltage events.
• Regulatory compliance: RoHS compliance simplifies environmental and supply‑chain acceptance for many installations.
