LGU2P181MELY

The LGU2P181MELY is a snap-in terminal type aluminum electrolytic capacitor designed for general-purpose power applications. It delivers a 180 µF capacitance at a 220 V rating in a compact φ20 × 25 mm can, optimized for board-level mounting with snap-in terminals.

Engineered for sustained operation up to 105°C, the device provides defined ripple-handling capability and long-term endurance, making it suitable for designs that require high-voltage bulk capacitance and reliable lifetime performance.

Key Features

• Capacitance and Voltage — 180 µF nominal capacitance at a rated voltage of 220 V with ±20% tolerance for bulk energy storage and smoothing.
• Snap-in Terminal Package — Radial, can-style snap-in mounting for secure board installation and straightforward assembly.
• High-temperature Endurance — Rated for operation from −40°C to +105°C with a specified lifetime of 3000 hours at 105°C when subjected to rated ripple and bias.
• Ripple Current Capability — 900 mA low-frequency ripple current at 120 Hz and 1.35 A high-frequency ripple current at 50 kHz, supporting applications with significant AC ripple stress.
• Electrical Loss — tan δ (dissipation factor) of 0.15 (max) measured at 20°C and 120 Hz for the 220 V rating, enabling predictable loss performance in AC-biased circuits.
• Leakage Current — Specified leakage current of 590 µA after voltage application, measurable at 20°C.
• Compact Footprint — Physical dimensions φ20 × 25 mm (L: 2.5 cm × D: 2.0 cm) for space-conscious power designs.
• Compliance and Packaging — RoHS compliant and supplied in tray packing for production-scale assembly; indicated as mass production status.

Typical Applications

• General-purpose power supplies — Bulk smoothing and output filtering where 220 V rated capacitance and defined ripple handling are required.
• Power conversion and conditioning — Energy storage and ripple attenuation in AC/DC or DC/DC conversion stages operating within the component’s voltage and temperature limits.
• Industrial electronics — Board-mounted bulk capacitance for industrial control and power circuitry exposed to elevated temperatures (up to 105°C) and continuous ripple stress.

Unique Advantages

• Rated for elevated temperatures — 3000-hour endurance at 105°C supports long-life deployments in thermally demanding environments.
• Defined high-frequency performance — Specified ripple current at 50 kHz (1.35 A) gives designers clear performance expectations for switching and high-frequency applications.
• Predictable dissipation — tan δ specified at 120 Hz and 20°C (0.15) allows accurate assessment of dielectric losses under AC conditions.
• Compact snap-in form factor — φ20 × 25 mm can with snap-in terminals simplifies PCB mounting while delivering substantial capacitance for its size.
• Production-ready packaging — Tray packing and mass production availability support efficient procurement and assembly for volume builds.
• Regulatory compliance — RoHS status provides material compliance for environmentally conscious designs.
