LGL2G561MELB40

The LGL2G561MELB40 is a Nichicon snap-in terminal aluminum electrolytic capacitor designed for high-voltage, high-temperature general-purpose applications. It delivers 560 µF capacitance at a 400 V rating in a compact φ30 × 40 mm can with tray packing for mass production.

Engineered for durability in elevated-temperature environments, this radial, can-type snap-in capacitor is specified for continuous operation up to 105°C with a 2000-hour endurance rating and defined ripple-current capability across low and high frequencies.

Key Features

• Voltage & Capacitance — 560 µF nominal capacitance rated at 400 V, suitable where high DC smoothing or energy storage is required in a single component footprint.
• Snap-in Radial Can Package — Snap-in terminal type (radial, can - snap-in) for secure PCB mounting and streamlined assembly in production environments; supplied in tray packing for mass production.
• High-Temperature Endurance — Rated operating temperature range of −25°C to +105°C with a guaranteed lifetime of 2000 hours at 105°C under D.C. bias plus rated ripple current.
• Ripple Current Performance — Specified ripple current of 1.66 A at 120 Hz and 2.374 A at 50 kHz, with frequency coefficients provided in the product family data for frequency scaling of ripple capability.
• Leakage Current Specified — Leakage current defined by I ≤ 3√(C·V) (μA) after 5 minutes application of rated voltage at 20°C, allowing predictable power-loss budgeting.
• Electrical Stability — Capacitance tolerance ±20% (at 120 Hz, 20°C) and a tan δ limit of 0.15 (max) at 400 V measured at 120 Hz; defined low-temperature impedance ratio Z(–25°C)/Z(+20°C) ≤ 8.
• Endurance & Shelf Life Criteria — After 2000 hours at 105°C (with D.C. bias plus rated ripple) the capacitor meets capacitance, tan δ and leakage limits; shelf-life recovery procedures and limits are specified in the datasheet.

Typical Applications

• General-purpose power electronics — Used where a 400 V, high-capacitance solution is required for DC link smoothing or bulk energy storage in industrial and commercial designs.
• High-temperature environments — Suitable for assemblies that must maintain capacitance and leakage characteristics up to 105°C with long-term endurance.
• Mass-production assemblies — Tray-packed snap-in format facilitates automated handling and consistent mounting in production lines.

Unique Advantages

• High-voltage, high-capacity combination — 560 µF at 400 V in a φ30 × 40 mm package reduces the need for multiple smaller capacitors while conserving board space.
• Proven thermal endurance — 2000 hours at 105°C with defined post-test limits gives predictable long-term performance for thermal-stressed designs.
• Defined ripple handling across frequencies — Published ripple-current values at 120 Hz and 50 kHz allow designers to size the capacitor for both low- and high-frequency ripple conditions using the family’s frequency coefficients.
• Predictable leakage and dissipation — Leakage current formula and tan δ specification permit accurate loss and thermal management calculations during design.
• Production-ready packaging — Tray packing and snap-in terminals streamline assembly and handling for high-volume manufacturing.
