LAS2G680MELZ20ZB

The LAS2G680MELZ20ZB is a snap‑in terminal aluminum electrolytic capacitor designed for general‑purpose power applications. Its snap‑in radial can construction and polarized design make it suitable for board‑level smoothing, filtering and energy‑storage roles where compact size and robust ripple handling are required.

Built for operation from −25°C to +105°C, this part emphasizes long endurance and improved safety under abnormal voltage conditions, making it a fit for equipment exposed to fluctuating line voltages or demanding thermal environments.

Key Features

• Electrical Performance — 68 µF rated capacitance at 400 V DC with ±20% tolerance; polarized device for DC smoothing and bulk energy storage.
• High‑Temperature Endurance — Specified to withstand 2000 hours of DC bias plus rated ripple current at 105°C, with defined limits for capacitance change, tan δ and leakage current after endurance testing.
• Ripple Current Capability — Rated ripple current of 510 mA at 120 Hz and 586.5 mA at 10 kHz, supporting higher effective ripple handling at elevated frequencies.
• Safety and Abnormal Voltage Performance — Designed with improved safety features for abnormally excessive voltage and a pressure relief vent that operates without dangerous failure modes.
• Compact Snap‑In Package — Radial, can‑type snap‑in mounting for secure board installation; nominal body footprint L: 2.0 cm × D: 2.2 cm.
• Environmental Compliance — RoHS directive compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• Power supply filtering — Bulk smoothing and ripple suppression in AC/DC and DC/DC power stages for equipment experiencing fluctuating input voltages.
• Industrial control equipment — Energy storage and decoupling in motor drives, inverters and control systems operating at elevated temperatures.
• Consumer and commercial electronics — General‑purpose DC link and smoothing applications where compact snap‑in mounting simplifies assembly.

Unique Advantages

• Long high‑temperature endurance: Rated for 2000 hours under rated ripple at 105°C, providing predictable aging and lifetime behavior in hot environments.
• Frequency‑responsive ripple handling: Specified ripple current values at 120 Hz and 10 kHz (510 mA and 586.5 mA respectively), enabling designers to account for frequency‑dependent stress.
• Improved abnormal‑voltage safety: Engineered safety features and a pressure relief vent reduce the risk of hazardous failure modes under excessive voltage conditions.
• Space‑efficient snap‑in package: Radial snap‑in can delivers secure board mounting and a small footprint (L 2.0 cm × D 2.2 cm) for compact power assemblies.
• RoHS compliant: Meets applicable RoHS requirements for environmental and regulatory conformity.
• Series‑level improvements: Smaller case sizes and higher ripple current capability compared with earlier LAQ series parts, offering an easy upgrade path where space and ripple performance matter.
