LAS2G151MELA30

The LAS2G151MELA30 is a snap-in terminal aluminum electrolytic capacitor from Nichicon's LAS series, offering 150 µF capacitance at a 400 V rating. It is designed as a compact, high-voltage bulk capacitor for general-purpose power electronics where high ripple capability and 105°C endurance are required.

Key value comes from its combination of high rated voltage, substantial low- and high-frequency ripple current capability, and a 2000-hour endurance rating at 105°C—making it suited for equipment exposed to voltage fluctuations and continuous high-temperature operation.

Key Features

• Rated Electricals — 150 µF nominal capacitance with a 400 V rated voltage and ±20% capacitance tolerance at 120 Hz, 20°C.
• Low Loss Characteristic — Maximum tanδ of 0.20 at 20°C and 120 Hz for predictable dissipation performance.
• Leakage Current — Specified leakage current of 730 µA to help manage standby and loss budgets.
• High Ripple Current Capability — 880 mA at 120 Hz (low frequency) and 1.012 A at 10 kHz (high frequency) to support bulk smoothing and ripple handling.
• High-Temperature Endurance — Rated for 2000 hours at 105°C under rated ripple and DC bias conditions, with stability criteria for capacitance, tanδ and leakage after test.
• Robust Safety Design — Series-level safety features include a pressure relief vent and design measures to tolerate abnormal excessive voltages without hazardous failure modes.
• Mechanical & Mounting — Snap-in radial can package (φ25 × 30 mm), tray packed for production handling and intended for through-hole snap-in mounting.
• Environmental Compliance — RoHS compliant per the provided product information.

Typical Applications

• High-voltage power supplies — Bulk smoothing and energy storage for 400 V rails where compact, high-voltage capacitance is required.
• Voltage-fluctuation environments — Suitable for equipment operating in areas with unstable line conditions, benefiting from the LAS series' abnormal-voltage tolerance and safety features.
• AC/DC rectifier smoothing — Handling rectified ripple currents and providing stable bulk capacitance at both low and higher ripple frequencies.

Unique Advantages

• High ripple handling at multiple frequencies: Specified ripple currents at 120 Hz and 10 kHz reduce the need for multiple parallel capacitors in many designs.
• 105°C, 2000-hour endurance: Long-term performance under elevated temperature and ripple stress supports reliable operation in demanding thermal environments.
• Compact snap-in package: φ25 × 30 mm radial can with snap-in terminals enables straightforward through-hole mounting and efficient board layout for high-voltage bulk applications.
• Safety-focused construction: Pressure relief vent and series-level abnormal-voltage measures help mitigate hazardous failure modes during overvoltage events.
• RoHS compliant and production-ready: Tray packing and mass production status simplify procurement and assembly for volume builds.
