LLG2W561MELC40

The LLG2W561MELC40 from Nichicon is a snap-in terminal aluminum electrolytic capacitor in the LLG series, designed as a one-rank smaller case size than the LLS series to support equipment downsizing. It provides 560 µF capacitance at a 450 V rating and is intended for general-purpose applications where a compact, high-voltage electrolytic capacitor is required.

Key value propositions include a compact snap-in radial can package, RoHS compliance, defined endurance at elevated temperature, and published ripple-current capability for effective power filtering and energy storage in compact designs.

Key Features

• Capacitance & Voltage — 560 µF capacitance rated for 450 V, suitable where high voltage capacitance is required.
• Compact Snap-In Package — Radial, can-type snap-in mounting designed to save board space; one rank smaller case size than LLS to aid equipment downsizing.
• Operating Temperature — Rated for operation from −25 °C to +85 °C consistent with the 450 V class in the LLG series.
• Endurance — Specified lifetime of 2000 hours at 85 °C under rated conditions, with post-test limits on capacitance, tan δ, and leakage current.
• Ripple Current Performance — Rated ripple current of 2.66 A at 120 Hz and 3.804 A at 100 kHz to support AC ripple handling in power circuits.
• Tolerance & Polarization — Capacitance tolerance of −20% to +20% and polarized construction for proper DC application.
• Regulatory — Compliant with RoHS directives (2011/65/EU, (EU)2015/863).
• Physical Dimensions — Body dimensions approximately L: 4 × D: 3.5 cm with a maximum seated height of 1.575 inch for mechanical planning.

Typical Applications

• General-purpose power filtering — Provides bulk capacitance and ripple absorption in circuits that require a compact, high-voltage electrolytic solution.
• Equipment downsizing — The one-rank smaller case size supports designs where reduced component footprint is a priority.
• Energy storage for power circuits — Used where polarized high-voltage capacitance and defined ripple-current capability are needed for transient energy buffering.

Unique Advantages

• Space-efficient form factor: One-rank smaller case size than LLS enables reduced board footprint without sacrificing rated capacitance.
• High-voltage capability: 450 V rating supports higher-voltage system designs that require reliable electrolytic capacitance.
• Documented endurance: 2000 hours at 85 °C provides a defined reliability baseline for thermal stress planning.
• Measured ripple performance: Published ripple-current values at 120 Hz and 100 kHz allow designers to size the capacitor against expected AC loads.
• RoHS compliance: Conforms to current RoHS directives for regulatory and environmental alignment.
• Snap-in mounting: Radial snap-in terminals simplify PCB mounting for through-hole assembly while ensuring secure mechanical retention.
