LAS2G121MELZ30

The LAS2G121MELZ30 is a snap‑in terminal aluminum electrolytic capacitor from Nichicon’s LAS series. It is a polarized, radial can (snap‑in) capacitor rated 400 V with 120 µF capacitance and ±20% tolerance, designed for general‑purpose use and equipment operating in environments with fluctuating supply voltages.

Engineered for elevated temperature endurance, the part is specified for 2000 hours at 105 °C and is RoHS compliant, delivering a balance of high voltage capability, ripple handling, and safety features suitable for industrial and commercial assemblies.

Key Features

• Electrical Rating: 120 µF capacitance at a 400 V rated voltage with ±20% tolerance, suitable for high‑voltage DC applications where a polarized electrolytic is required.
• High‑Temperature Endurance: Specified for 2000 hours at 105 °C under rated ripple current and DC bias, supporting long‑life performance in elevated ambient conditions.
• Ripple Current Performance: Rated ripple current of 760 mA at 120 Hz and 874 mA at 10 kHz; frequency coefficient data indicate ripple capability increases with frequency (e.g., 1.00 at 120 Hz, 1.15 at 10 kHz).
• Package & Mounting: Radial, snap‑in can for secure board mounting and mechanical stability in chassis or power modules.
• Safety Features: Pressure relief vent and improved safety measures for abnormally excessive voltage, designed to prevent dangerous conditions such as flames or case dispersion.
• Operating Range: Rated for operation from −25 °C to +105 °C, allowing use across a broad temperature window common in industrial equipment.
• Environmental Compliance: RoHS compliant in accordance with the LAS series declaration.

Typical Applications

• General‑purpose industrial equipment: Suited for assemblies that require robust electrolytic capacitance and rated ripple handling in environments with fluctuating supply voltages.
• Power modules and DC bus systems: Provides high‑voltage bulk capacitance where a 400 V rating and specified ripple currents are needed for smoothing or energy buffering within the design constraints.
• Commercial and factory electronics: Useful in systems that demand reliable, long‑life capacitors at elevated operating temperatures up to 105 °C.

Unique Advantages

• High voltage capability: 400 V rating enables use in higher DC rails without series stacking, simplifying design.
• Long‑life thermal endurance: 2000‑hour rating at 105 °C under rated conditions supports extended service life in hot operating environments.
• Measured ripple handling: Specified ripple currents at both low and high frequencies with published frequency coefficients to help size thermal and ripple performance accurately.
• Safety‑oriented design: Pressure relief vent and improved abnormal voltage protections reduce risk under overvoltage conditions.
• Secure mounting: Snap‑in radial can package provides mechanical stability for board and chassis installations.
• Regulatory compliance: RoHS conformity supports deployment in regions requiring restricted substance compliance.
