LGW2W561MELC50

The LGW2W561MELC50 is a radial, can‑style aluminum electrolytic capacitor with snap‑in terminals, designed for high‑voltage, high‑ripple environments. It delivers 560 µF capacitance at a 450 V rating and is specified for continuous operation up to 105°C.

Engineered for general‑purpose power applications that require sustained ripple handling, this component combines high ripple current capability with a 3,000‑hour endurance under rated ripple at 105°C and RoHS compliance for regulated designs.

Key Features

• Electrical characteristics — 560 µF nominal capacitance with ±20% tolerance and polarized construction rated at 450 V.
• High ripple capability — Rated ripple current values include 2.85 A at 120 Hz and 4.075 A at 50 kHz; frequency coefficients for 400–450 V range from 0.77 (50 Hz) to 1.43 (50 kHz and above), with 120 Hz defined as 1.00.
• Thermal and endurance — Operating temperature range of −25°C to +105°C and qualified to withstand 3,000 hours of rated ripple current at 105°C; endurance limits specify capacitance change within ±20%, tan δ ≤ 200% of initial, and leakage current ≤ initial specified value after the test.
• Low‑temperature stability — Impedance ratio Z(−25°C)/Z(+20°C) up to 8 for 400–450 V units, aiding performance in cooler environments within the specified category temperature range.
• Leakage current specification — Leakage current after 5 minutes at 20°C follows I ≤ 3√CV (µA), where C is capacitance (µF) and V is voltage (V).
• Package & mounting — Radial, can‑snap‑in package with snap‑in terminal mounting for secure PCB installation; physical dimension L: 5 × D: 3.5 cm.
• Regulatory — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• High‑voltage power supplies — Bulk filtering and smoothing at up to 450 V with high ripple current capability for stabilized DC outputs.
• Industrial power conversion — DC link and energy‑buffer applications that require sustained ripple endurance at elevated temperatures (105°C, 3,000 hours).
• Backup and energy storage subsystems — High capacitance at 450 V for bulk energy support in UPS and related systems where long ripple‑current life is required.

Unique Advantages

• High ripple endurance: Specified to withstand 3,000 hours of rated ripple current at 105°C, reducing replacement frequency in high‑stress power designs.
• Wide thermal capability: Continuous operation to 105°C supports dense power assemblies and higher ambient installations.
• Verified leakage control: Leakage current limited by the I ≤ 3√CV formula provides predictable bias‑on behavior after voltage application.
• Frequency‑aware ripple rating: Published frequency coefficients and ripple current values allow designers to scale ripple handling across 50 Hz to >50 kHz applications.
• Robust package: Snap‑in, radial can design for reliable PCB mounting and mechanical retention in power modules.
• RoHS compliant: Meets RoHS (2011/65/EU, (EU)2015/863) requirements for regulated product lines.
