LGN2W561MELC50

The LGN2W561MELC50 is a snap‑in terminal aluminum electrolytic capacitor rated 560 µF at 450 V, designed for general‑purpose power applications that require a compact, high‑voltage polarized capacitor. It is a smaller‑sized “snailer” style from the LGN series, offering high ripple tolerance and extended endurance at elevated temperatures.

Built for operation from −25 °C to +105 °C with a guaranteed 3000 hours endurance under rated ripple current at 105 °C, this part targets designs that need high‑temperature reliability and secure snap‑in mounting.

Key Features

• Capacitance & Voltage — 560 µF nominal capacitance at a 450 V rated voltage with ±20% tolerance, suitable for high‑voltage energy storage and smoothing tasks.
• High‑Temperature Endurance — Rated to operate up to 105 °C and specified to withstand 3000 hours application of rated ripple current at 105 °C, providing long service life under thermal stress.
• Snap‑in Radial Can Package — Snap‑in terminal type (radial, can – snap‑in) enables robust PCB mounting and mechanical stability in power assemblies.
• Ripple Current Performance — Rated ripple currents of 1.99 A at 120 Hz and 2.846 A at 100 kHz, supporting applications with significant AC stress on the capacitor.
• Polarized Construction — Polarized electrolytic design for DC filtering and energy storage where polarity is defined.
• Smaller‑Sized Snailer — One rank smaller case size than LGU series units, allowing tighter packing in constrained enclosures.
• RoHS Compliance — Compliant to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General‑Purpose Power Supply Circuits — Polarized snap‑in construction and 450 V rating make it suitable for smoothing and bulk energy storage in high‑voltage power supplies.
• High‑Temperature Environments — Endurance at 105 °C for 3000 hours supports equipment that operates with elevated ambient or internal temperatures.
• High‑Ripple DC Systems — Specified ripple current at 120 Hz and 100 kHz addresses applications with significant AC components on DC rails.

Unique Advantages

• Extended High‑Temperature Life: 3000 hours endurance at 105 °C under rated ripple current reduces replacement frequency in thermally stressed designs.
• Compact Snailer Form Factor: One rank smaller case size than the LGU series enables denser board layouts without sacrificing voltage or capacitance.
• Robust Snap‑in Mounting: Snap‑in terminals provide secure mechanical retention for through‑hole PCB assemblies in power modules.
• Verified Ripple Capability: Published ripple current ratings at both low (120 Hz) and high (100 kHz) frequencies help designers match the part to converter and inverter stress profiles.
• Regulatory Compliance: RoHS conformance supports environmental and regulatory requirements for commercial and industrial products.
