LGNW6561MELC45

The LGNW6561MELC45 is a snap‑in terminal aluminum electrolytic capacitor designed for general‑purpose power applications requiring high voltage and elevated temperature endurance. It delivers 560 µF capacitance at a 420 V rating in a smaller-sized snap‑in can, offering high ripple tolerance and sustained performance at up to 105°C.

Engineered for environments that demand sustained ripple handling and long endurance, this capacitor is suited to designs where robust DC bias performance and compact high‑voltage bulk capacitance are required.

Key Features

• Capacitance & Voltage — 560 µF nominal capacitance with a 420 V rated voltage and ±20% tolerance, providing substantial bulk energy storage for high‑voltage circuits.
• High‑Temperature Endurance — Specified for operation to 105°C and rated to withstand 3000 hours of rated ripple current at 105°C, supporting sustained operation in thermally demanding installations.
• Snap‑in Radial Can Package — Snap‑in terminal mounting in a radial can simplifies board assembly for power modules and allows secure mechanical retention.
• Ripple Current Performance — Rated ripple current of 2.1 A at 120 Hz and 3.003 A at 100 kHz, enabling effective ripple handling across a wide frequency range.
• Compact Size — One rank smaller case size than the LGU series; physical footprint measures L: 4.5 × D: 3.5 cm with a maximum seated height of 1.772 inch for space‑constrained designs.
• Reliability Characteristics — Meets leakage current specification and tan δ limits per series datasheet; shelf life and endurance requirements defined for practical lifecycle planning.
• RoHS Compliance — Compliant with RoHS directives (2011/65/EU, (EU)2015/863), supporting regulatory requirements for restricted substances.

Typical Applications

• Power Electronics — Bulk filtering and energy storage in high‑voltage power supplies where 420 V rating and 560 µF capacitance are required.
• Industrial Equipment — Use in industrial power modules and converters that operate at elevated temperatures up to 105°C and require sustained ripple endurance.
• General‑Purpose High‑Voltage Designs — Suitable for general‑purpose applications needing a compact, high‑voltage electrolytic capacitor with snap‑in mounting.
