LGM2W561MELB45

The LGM2W561MELB45 is a snap‑in terminal aluminum electrolytic capacitor from Nichicon's LGM series, offering a 560 µF capacitance at a 450 V rating. It is an ultra‑smaller‑sized snap‑in radial can—one rank smaller than the LGL series—designed to support general‑purpose equipment where compact, high‑voltage capacitors are required.

Key value comes from its combination of 450 V dielectric strength, 105°C operating temperature, and a rated endurance of 2000 hours at 105°C, providing reliable high‑temperature performance in space‑constrained designs.

Key Features

• Electrical — Capacitance & Voltage: 560 µF nominal capacitance with a 450 V rated voltage and ±20% tolerance at 120 Hz, 20°C.
• High‑Temperature Operation: Rated operating temperature range of –25°C to +105°C, with endurance specified at 2000 hours at 105°C under DC bias plus rated ripple current.
• Ripple Current Capability: Rated ripple current of 1.2 A (1200 mArms) at 105°C, 120 Hz; specified higher‑frequency ripple current of 1.716 A at 50 kHz.
• Reliability Criteria: Endurance limits specify capacitance change within ±20%, tan δ ≤ 200% of initial, and leakage current not exceeding initial specified values after the endurance test.
• Compact Snap‑In Package: Radial, can style with snap‑in terminals in an ultra‑smaller case (size: L 4.5 × D 3.0 cm / 30 × 45 mm for this part), suited for equipment downsizing relative to the LGL series.
• Polarized Type & Leakage: Polarized aluminum electrolytic construction; leakage current specification I ≤ 3√(C·V) µA after 5 minutes at 20°C (per datasheet formula).
• RoHS Compliance: Compliant to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General Purpose Equipment: Intended for general‑purpose applications that require a 560 µF, 450 V snap‑in electrolytic capacitor.
• Space‑Constrained Designs: The LGM series is ultra‑smaller‑sized and one rank smaller than LGL, making this part suitable where cabinet or PCB space is limited.
• High‑Temperature Environments: Suitable for equipment operating up to +105°C with a specified 2000‑hour endurance at that temperature.

Unique Advantages

• Compact high‑voltage solution: 450 V rating combined with a 560 µF value in a reduced case (30 × 45 mm) supports downsized designs without sacrificing capacitance.
• Designed for elevated temperatures: Rated to +105°C with a 2000‑hour endurance specification, enabling reliable performance in hotter operating conditions.
• Robust ripple handling: 1.2 A rated ripple at 120 Hz (105°C) and a specified higher‑frequency ripple current figure provide quantifiable AC stress capability.
• Clear reliability specs: Endurance and shelf‑life criteria are defined (capacitance, tan δ, leakage), allowing predictable qualification in designs.
• RoHS compliant: Meets current RoHS directives for use in compliant assemblies.
• Snap‑in mounting: Radial, snap‑in terminals simplify board retention and mechanical stability in upright installations.

Why Choose LGM2W561MELB45?
