LGU2E821MELB

The LGU2E821MELB is a snap-in terminal aluminum electrolytic capacitor from Nichicon’s LGU series. It delivers 820 µF capacitance at a 250 V rating in a radial snap-in can designed for general-purpose power applications.

Engineered for extended operation at elevated temperatures, this part supports continuous operation up to 105°C with a 3000-hour endurance specification and is supplied in tray packing for production use.

Key Features

• Capacitance & Voltage: 820 µF rated at 250 V, offering bulk energy storage for power circuits.
• Tolerance: ±20% capacitance tolerance (measured at 120 Hz, 20°C) for predictable performance in design.
• High ripple current capability: 2.30 A at 120 Hz (low frequency) and 3.45 A at 50 kHz (high frequency), enabling effective filtering under ripple conditions.
• Loss characteristics: tan δ = 0.15 maximum at 20°C and 120 Hz, supporting stable dissipation behavior for the rated voltage range.
• Leakage current: Specified leakage current of 1350 µA after standard voltage application, aligned with expected electrolytic behavior.
• Endurance at elevated temperature: Rated for 3000 hours at 105°C with DC bias plus rated ripple current, meeting the LGU series endurance criteria.
• Operating temperature range: –40°C to +105°C to accommodate a wide range of thermal environments.
• Mechanical & packaging: Snap-in terminal radial can, size φ30 × 45 mm (L: 4.5 × D: 3 cm) and supplied in tray packing for streamlined assembly.
• Environmental compliance: RoHS compliant.

Typical Applications

• General-purpose power systems: Bulk energy storage and smoothing in circuits requiring a 250 V rated electrolytic capacitor.
• Power supply filtering: Filtering and ripple absorption where 820 µF capacitance and high ripple current ratings improve voltage stability.
• Industrial electronics: Applications that demand continuous operation at elevated temperatures, supported by a 3000-hour life at 105°C.

Unique Advantages

• High ripple current handling: 2.30 A (120 Hz) and 3.45 A (50 kHz) ratings reduce thermal stress and support robust filtering under dynamic loads.
• Long endurance at 105°C: 3000-hour rated life under rated ripple conditions provides predictable lifespan in hot environments.
• Wide operating temperature range: –40°C to +105°C covers many industrial and general-purpose applications.
• Compact snap-in package: φ30 × 45 mm radial can with snap-in terminals for secure mounting and straightforward board integration.
• Production-ready packaging: Tray packing and mass production status support high-volume assembly and supply continuity.
• Standards-aligned electrical behavior: Specified tan δ and leakage current values provide measurable parameters for design validation.
