LGA2W181MELA30

The LGA2W181MELA30 is a snap-in terminal aluminum electrolytic capacitor designed for general-purpose power applications. It combines high capacitance and high ripple-current capability in a radial can snap-in package for durable PCB mounting.

Key value comes from its 450 V rating, 180 µF capacitance, rated operation to 105°C, and long-life endurance—supporting demanding power-filtering and energy-storage roles where sustained ripple handling and reliability matter.

Key Features

• Capacitance & Voltage — 180 µF rated capacitance at 450 V provides bulk energy storage and smoothing for high-voltage power rails.
• High Ripple Current — Rated ripple current of 1.32 A at 120 Hz and 1.888 A at 50 kHz supports continuous AC ripple handling in power circuits.
• Long Life Endurance — Endurance specified as 5000 hours at 105°C with rated ripple current applied; capacitance, dissipation factor and leakage stay within datasheet limits after the test.
• Low ESR — Equivalent series resistance of 200 mΩ at 120 Hz helps minimize heating and improve filtering performance under load.
• Wide Operating Temperature — Specified operating range from −40°C to +105°C for stable operation across common industrial temperature environments.
• Polarized, Snap-In Package — Radial can, snap-in mounting simplifies PCB assembly and secures the component for robust mechanical retention.
• Leakage and Loss Characteristics — Leakage current defined as I ≤ 3√CV (µA) after 5 minutes at 20°C; tan δ ≤ 0.20 at 120 Hz and 20°C, ensuring predictable electrical behavior.
• RoHS Compliant — Meets RoHS directive (2011/65/EU, (EU)2015/863) for restricted substances compliance.

Typical Applications

• Power Supply Filtering — Bulk smoothing and ripple reduction on high-voltage rails where 450 V rating and 180 µF capacitance are required.
• Industrial Power Electronics — Energy buffering and decoupling in converters and inverters that demand continuous ripple handling and durable performance at elevated temperatures.
• General-Purpose High-Voltage Circuits — DC link and charge storage in systems where long-life endurance (5000 h at 105°C) improves maintenance intervals and uptime.

Unique Advantages

• High ripple tolerance: Rated ripple currents of 1.32 A (120 Hz) and 1.888 A (50 kHz) enable reliable operation under continuous AC stress.
• Durability under heat: 5000-hour endurance at 105°C preserves capacitance and leakage performance over long service intervals.
• Low ESR for improved efficiency: 200 mΩ ESR at 120 Hz reduces internal heating and enhances filtering effectiveness.
• Practical package form: Radial, snap-in can offers secure PCB anchoring for robust assemblies.
• Predictable electrical behavior: Clear leakage current formula and tan δ limits provide engineers with verifiable performance metrics.
• Regulatory compliance: RoHS conformity supports deployment in regions requiring restricted-substance compliance.
