LAS2W181MELB30

The LAS2W181MELB30 is a snap-in terminal, large-can aluminum electrolytic capacitor rated at 450 V with 180 µF capacitance and ±20% tolerance. It is designed for general-purpose high-voltage smoothing and filtering in equipment that requires robust ripple handling and extended high-temperature endurance.

Built for demanding operating environments, this capacitor delivers 2000 hours of endurance at 105°C, high ripple-current capability, and safety features for abnormal voltage conditions, making it suitable for power conversion and industrial applications where reliability at elevated voltage and temperature is required.

Key Features

• Electrical Performance — 180 µF capacitance at a 450 V rated voltage with capacitance tolerance of -20% to +20% and tanδ (DF) of 0.20 (measured at 20°C, 120 Hz).
• High Ripple Capability — Low-frequency ripple current of 970 mA (120 Hz) and high-frequency ripple current of 1.115 A (10 kHz) to support demanding smoothing and DC‑link applications.
• Temperature and Lifetime — Rated for continuous operation from -25°C to 105°C with an endurance of 2000 hours at 105°C under rated ripple conditions.
• Snap-In Can Package — Radial, snap-in can construction (φ30 × 30 mm) for secure board mounting and simplified assembly; supplied in tray packing and available in mass production.
• Leakage and Loss Characteristics — Specified leakage current of 850 µA and low dissipation factor supporting predictable performance in DC circuits.
• Safety Design — Pressure relief vent and improved safety features for abnormally excessive voltage, designed to operate safely without dangerous failures under the specified test conditions.

Typical Applications

• High-Voltage Power Supplies — Bulk smoothing and energy storage in 450 V-class power supplies where stable capacitance and controlled leakage are required.
• Industrial Power Conversion — DC-link and filtering in converters and inverters that demand sustained ripple performance at elevated temperatures.
• Motor Drives and Controls — Energy buffering and smoothing for motor controllers and drives operating in industrial environments up to 105°C.

Unique Advantages

• Robust High-Temperature Endurance: 2000 hours at 105°C guarantees long-term performance under sustained thermal stress.
• High-Voltage, High-Capacitance Combination: 450 V rating paired with 180 µF provides substantial bulk capacitance for high-voltage DC applications.
• Superior Ripple Handling: Specified ripple currents at both low and high frequencies (970 mA at 120 Hz; 1.115 A at 10 kHz) support a wide range of switching and line-frequency conditions.
• Compact Snap-In Form Factor: Smaller case size with snap-in terminals simplifies board layout and mechanical retention for high-density assemblies.
• Safety-Minded Design: Pressure relief and abnormal-voltage protections reduce risk of dangerous failure modes during overvoltage events.
• RoHS Compliant and Production Ready: RoHS status compliant and supplied in tray packing for consistent handling in production environments.
