LGU2C561MELB

The LGU2C561MELB from Nichicon is a snap-in, polarized aluminum electrolytic capacitor in the LGU series, rated 560 µF at 160 V. It is a tray-packed, radial can (snap-in) device engineered for general-purpose electronic equipment that requires stable bulk capacitance in a compact footprint.

Key value propositions include rated endurance under sustained ripple at elevated temperature, defined high- and low-frequency ripple current capability, low leakage, and a temperature range suitable for industrial and commercial applications up to 105°C.

Key Features

• Capacitance & Tolerance — 560 µF nominal capacitance with ±20% tolerance (measured at 120 Hz, 20°C).
• Rated Voltage & Polarization — 160 V rated voltage; polarized aluminum electrolytic design for DC applications.
• Endurance & Temperature Range — Specified lifetime of 3000 hours at 105°C; operating temperature range −40°C to +105°C.
• Ripple Current & Frequency Response — Low-frequency ripple current of 1.67 A at 120 Hz and high-frequency ripple current of 2.505 A at 50 kHz. Frequency coefficients for the 160–250 V range: 50 Hz = 0.81, 60 Hz = 0.85, 120 Hz = 1.00, 300 Hz = 1.17, 1 kHz = 1.32, 10 kHz = 1.45, 50 kHz or more = 1.50.
• Leakage & Dissipation — Measured leakage current 890 µA; tangent of loss angle (tan δ) max. 0.15 at 120 Hz, 20°C for the 160–420 V range.
• Package & Mounting — Snap-in terminal type in a radial, can-style package; physical size approximately φ30 × 25 mm (diameter × length); tray packing for board-level assembly.
• Regulatory Compliance — Compliant with RoHS (2011/65/EU, (EU)2015/863).

Typical Applications

• General-purpose electronic equipment — Where a 560 µF, 160 V polarized snap-in aluminum electrolytic capacitor is required for bulk capacitance.
• High-ripple environments — Suitable for applications that use specified ripple current levels, with defined endurance for 3000 hours at 105°C and frequency-dependent ripple handling.
• Space-constrained assemblies — Compact φ30 × 25 mm footprint and snap-in mounting for assemblies requiring radial can capacitors with tray packing.

Unique Advantages

• Defined high-temperature endurance — Endurance rated for 3000 hours at 105°C, providing predictable long-term behavior under sustained ripple and elevated temperature.
• Frequency-aware ripple capability — Manufacturer-provided frequency coefficients let designers scale rated ripple current across 50 Hz to 50 kHz+ for accurate thermal and reliability planning.
• Low leakage characteristic — Measured leakage current of 890 µA supports stable DC performance after voltage application.
• Compact snap-in form factor — φ30 × 25 mm radial can with snap-in terminals and tray packing simplifies board-level assembly in constrained layouts.
• Clear electrical limits — Specified tan δ (0.15 at 120 Hz, 20°C) and ±20% capacitance tolerance enable predictable AC and DC behavior for design validation.
• RoHS compliant — Conforms to applicable RoHS directives for regulatory alignment in commercial and industrial products.
