LGG2D681MELA30

The LGG2D681MELA30 is a Nichicon LGG series aluminum electrolytic capacitor in a snap-in terminal, designed for compact, high-voltage general-purpose applications. It provides 680 µF capacitance at 200 V in an ultra-smaller-sized snap-in can (φ25 × 30 mm), suited for equipment downsizing.

Engineered for durability, this part is rated for operation from −40 °C to 105 °C with a 2000-hour endurance at 105 °C, and is RoHS compliant. Key electrical characteristics include low-frequency ripple capability and controlled loss (tan δ), making it appropriate where stable bulk capacitance and ripple handling are required.

Key Features

• Core Electrical: 680 µF nominal capacitance with a rated voltage of 200 V and a tolerance of ±20% (120 Hz, 20 °C).
• Loss and Stability: tan δ specified at 0.15 (measurement at 120 Hz, 20 °C), supporting stable impedance performance within the rated conditions.
• Ripple Current Performance: Low-frequency ripple current 1.6 A at 120 Hz and high-frequency ripple current 2.4 A at 100 kHz, enabling effective smoothing and filtering under AC ripple load.
• Leakage Current: Specified leakage current of 1100 µA at rated conditions, consistent with series performance expectations.
• Reliability & Endurance: Life rating of 2000 hours at 105 °C under DC bias plus rated ripple; meets endurance criteria for capacitance change, tan δ, and leakage current after the test.
• Mechanical & Mounting: Snap-in terminal radial can package (φ25 × 30 mm) for secure PCB insertion and tray packing for production handling.
• Environmental: Compliant with RoHS (2011/65/EU,(EU)2015/863).

Typical Applications

• Power supplies and power conversion: Bulk smoothing and filtering in medium-voltage rail applications where 200 V rating and 680 µF capacitance are required.
• Industrial equipment: Energy storage and decoupling in general-purpose industrial power electronics demanding a compact, high-voltage electrolytic solution.
• Smaller footprint designs: Equipment and systems targeting size reduction, leveraging the LGG series' ultra-smaller-sized case to save board and chassis space.

Unique Advantages

• Compact snap-in package for downsizing: One rank smaller case size than the predecessor series, helping reduce enclosure and PCB space without compromising voltage or capacitance.
• High ripple handling: Combined low- and high-frequency ripple ratings (1.6 A at 120 Hz, 2.4 A at 100 kHz) support robust filtering across a range of operating conditions.
• Designed for elevated-temperature operation: Rated −40 °C to 105 °C with a 2000-hour endurance at 105 °C for sustained high-temperature performance.
• Predictable electrical behavior: Defined tan δ and leakage current figures enable straightforward inclusion in design margin and thermal budgets.
• Production-ready packaging and availability: Tray packing and mass-production status support efficient procurement and assembly.
• Regulatory compliance: RoHS-compliant construction for use in regulated markets.
