LAS2G680MELZ20

The LAS2G680MELZ20 is a snap-in terminal aluminum electrolytic capacitor from Nichicon's LAS series. It delivers 68 µF at 400 V in a compact, snap-in can package designed for general-purpose power electronics.

Engineered for demanding thermal and electrical conditions, this capacitor supports operation from -25°C to 105°C and is specifically suited for equipment operating in voltage-fluctuating environments where elevated ripple tolerance and safety under abnormal voltage are required.

Key Features

• Electrical Rating — 68 µF nominal capacitance with a 400 V rated voltage and ±20% tolerance, suitable for bulk smoothing and filtering in high-voltage circuits.
• High-temperature Endurance — Rated for operation up to 105°C with an endurance of 2000 hours when subjected to DC bias plus rated ripple current at 105°C.
• Ripple Current Capability — Rated ripple current of 510 mA at 120 Hz and 586.5 mA at 10 kHz, with frequency coefficients provided for other operating frequencies.
• Snap-in Radial Can Package — Snap-in terminal, radial can construction for secure PCB mounting and reliable mechanical retention.
• Improved Safety Features — Designed with a pressure relief vent and permissible abnormal voltage handling to reduce hazardous failure modes under abnormal conditions.
• Compact, Smaller-sized Design — Smaller case sizes compared with the LAQ series while offering higher ripple current handling.
• Operating Range and Stability — Specified for -25°C to +105°C; impedance ratio Z(-25°C)/Z(+20°C) up to 8 and tan δ maximum 0.20 at 120 Hz, 20°C.
• RoHS Compliant — Conforms to RoHS directive (2011/65/EU, (EU)2015/863).
• Marking and Identification — Printed with white lettering on a black sleeve for clear polarity and value identification.

Typical Applications

• Power Supply Filtering — Bulk smoothing and ripple suppression in high-voltage power supplies where 400 V rating and elevated ripple capability are required.
• Power Conversion Modules — DC-link and smoothing capacitors in converters and inverters operating in environments with voltage fluctuation.
• Industrial Equipment — General-purpose energy storage and filtering for industrial systems subject to temperature extremes and variable supply conditions.

Unique Advantages

• High-temperature reliability: 2000-hour endurance at 105°C under rated ripple current provides predictable life and performance in hot operating environments.
• Enhanced safety under abnormal voltage: Pressure relief vent and permissible abnormal voltage design reduce the risk of hazardous failures during voltage excursions.
• Compact footprint with strong ripple capability: Smaller case size than comparable LAQ series parts while delivering higher ripple current, enabling denser power designs.
• Clear electrical characterization: Specified ripple currents at 120 Hz and 10 kHz plus frequency coefficients allow designers to estimate performance across frequency ranges.
• Regulatory compliance: RoHS conformity supports use in designs requiring lead-free directive compliance.
