LGU2Z561MELB

The LGU2Z561MELB is a snap‑in terminal aluminum electrolytic capacitor designed for general‑purpose power electronics. Built to operate up to 105°C with a rated voltage of 180 V and a capacitance of 560 µF, it targets systems requiring robust bulk energy storage and high ripple handling in compact radial can packages.

Key value propositions include high ripple current capability, long endurance at elevated temperature, and a compact φ30 × 25 mm can with snap‑in mounting for reliable board retention in high‑stress environments.

Key Features

• Capacitance & Voltage: 560 µF nominal capacitance at a rated voltage of 180 V, with ±20% tolerance for predictable energy storage and filtering.
• High‑temperature Endurance: Rated for operation from −40°C to +105°C, with an endurance of 3000 hours at 105°C under rated ripple and DC bias.
• Snap‑in Radial Package: φ30 × 25 mm radial can with snap‑in terminals for secure board mounting and ease of assembly; supplied in tray packing for mass production.
• Low Loss Characteristics: Specified tan δ of 0.15 (measurement conditions per series specification) to help maintain stable AC behavior and lower heating under ripple conditions.
• High Ripple Current Capability: 1.67 A at 120 Hz (low frequency) and 2.505 A at 50 kHz (high frequency) to support demanding smoothing and decoupling duties.
• Leakage Current: Low leakage current specified at 950 µA to minimize standby losses and maintain system efficiency.
• Environmental Compliance: RoHS compliant for regulated‑market use.

Typical Applications

• Industrial Power Supplies: Bulk filtering and energy storage in high‑voltage DC rails where 180 V rating and high ripple current are required.
• Motor Drives and Inverters: DC‑link smoothing and transient buffering in drive electronics benefiting from the capacitor’s high ripple capability and 105°C endurance.
• Uninterruptible Power Supplies (UPS) and Backup Systems: Energy storage and smoothing for intermediate DC stages where long life at elevated temperature matters.
• Power Conversion Modules: Smoothing and decoupling in isolated and non‑isolated converters used in industrial and infrastructure equipment.

Unique Advantages

• High thermal endurance: 3000 hours at 105°C ensures stable performance in high ambient temperature installations and during sustained ripple stress.
• Strong ripple handling: Specified ripple currents at both low and high frequencies reduce the need for parallel components and simplify thermal design.
• Compact, secure mounting: Snap‑in radial can (φ30 × 25 mm) offers a space‑efficient footprint with robust mechanical retention for automated assembly.
• Predictable electrical behavior: ±20% capacitance tolerance and a defined tan δ value support reliable circuit design and predictable filtering performance.
• Low leakage: 950 µA leakage current helps minimize standby losses and supports longer service intervals for systems with low idle power budgets.
• Manufacturing ready: Tray packing and mass production status facilitate volume procurement and consistent supply chain handling.
