LAS2G181MELB25

The LAS2G181MELB25 is an aluminum electrolytic, snap-in terminal capacitor from Nichicon's LAS series, rated at 180 µF and 400 V DC. It combines a compact radial can package (φ30 × 25 mm) with design attributes targeted at high-temperature and high-ripple environments.

Designed for general-purpose electronic equipment and applications exposed to voltage fluctuation, this part offers 105°C permissible abnormal-voltage behavior, 2000 hours endurance at 105°C, and RoHS compliance for modern manufacturing requirements.

Key Features

• Capacitance & Voltage — 180 µF rated capacitance at 400 V DC, ±20% tolerance (120 Hz, 20°C).
• High-temperature Endurance — Qualified for 2000 hours of DC bias plus rated ripple current at 105°C, meeting LAS series endurance criteria.
• High Ripple Current Handling — 950 mA low-frequency ripple current (120 Hz) and 1.093 A high-frequency ripple current (10 kHz), enabling robust performance in power applications.
• Leakage and Loss Characteristics — Low leakage current (specified 800 µA) and a tangent of loss angle (tan δ) of 0.20 max at 20°C, 120 Hz for stable electrical performance.
• Snap-In Radial Can Package — Snap-in terminal mounting in a compact φ30 × 25 mm can simplifies board insertion and mechanical retention for high-density assemblies.
• Safety Features — Pressure relief vent designed to operate under abnormal conditions without dangerous outcomes, supporting safer operation in fluctuating-voltage environments.
• Regulatory Compliance — RoHS compliant for use in lead-free manufacturing processes.

Typical Applications

• General-purpose electronic equipment — Provides bulk capacitance and energy storage where a 400 V, 180 µF snap-in solution is required.
• Voltage-fluctuating environments — Suited for equipment used in areas with unstable supply voltages due to the LAS series' improved safety features and permissible abnormal-voltage characteristics.
• High-ripple power stages — Serves power supply and converter circuits that require sustained ripple current handling at both low and high frequencies.

Unique Advantages

• Long high-temperature life: 2000 hours endurance at 105°C under rated ripple and DC bias delivers predictable long-term behavior in hot operating conditions.
• High ripple capability: Dual-frequency ripple ratings (950 mA at 120 Hz, 1.093 A at 10 kHz) support power designs that must handle varying ripple spectra.
• Compact snap-in form factor: φ30 × 25 mm radial can with snap-in terminals provides a space-efficient solution for through-hole assemblies requiring secure mechanical mounting.
• Measured electrical stability: Specified tan δ (≤0.20) and controlled leakage (800 µA) help maintain circuit performance over temperature and time.
• Built-in safety vent: Pressure relief mechanism reduces risk under abnormal voltages, supporting safer operation in demanding environments.
• RoHS compliant and production ready: Tray-packed, mass-production status simplifies procurement and assembly for volume manufacturing.
