LGG2P681MELZ40

The LGG2P681MELZ40 is a 680 µF, 220 V aluminum electrolytic capacitor in a snap-in can package designed for general-purpose power applications. Built to the LGG series' ultra-smaller-sized snap-in format, it delivers high-temperature capability and long-term endurance for compact power system designs.

Key attributes include a 105 °C operating rating, RoHS compliance, a compact φ22×40 mm package (Size: L: 4 × D: 2.2 cm) and a rated lifetime of 2000 hours at 105 °C under rated conditions—making it suitable for applications that require reliable bulk capacitance and ripple handling in reduced footprints.

Key Features

• Capacitance & Tolerance — 680 µF nominal capacitance with ±20% tolerance at 120 Hz, 20 °C, providing predictable bulk energy storage and filtering performance.
• Rated Voltage — 220 V DC rating for medium-voltage power rails and converters.
• High Temperature Endurance — Rated to operate from −40 °C to +105 °C with an endurance specification of 2000 hours at 105 °C when DC bias plus rated ripple current are applied.
• Ripple Current Capability — Specified ripple performance: 1.65 A at 120 Hz (low frequency) and 2.475 A at 100 kHz (high frequency), supporting smoothing and decoupling under realistic ripple conditions.
• Snap-In, Radial Can Package — Snap-in terminal mounting and radial can construction for robust mechanical retention and straightforward PCB assembly in through-hole designs.
• Leakage and Loss Characteristics — Leakage current meets I ≤ 3√CV (µA) after 5 minutes at 20 °C; tangent of loss angle (tan δ) for the applicable voltage range is specified to ensure predictable dissipation (tan δ max. 0.15 for voltages in the 160–420 V range).
• Series Design Advantage — Part of the LGG series, which is described as one rank smaller in case size than LGN, enabling equipment downsizing where space is constrained.
• RoHS Compliant — Conforms to RoHS directive requirements for reduced hazardous substances.

Typical Applications

• Power Supply Filtering — Bulk smoothing and ripple reduction on medium-voltage DC rails in industrial and consumer power supplies.
• Power Conversion — Energy storage and decoupling in AC/DC and DC/DC converters where a 220 V rated capacitor and 680 µF value are appropriate.
• Industrial Electronics — Robust high-temperature performance for control equipment, inverters, and power modules operating up to 105 °C.

Unique Advantages

• Compact High-Voltage Bulk Capacitance: 680 µF at 220 V in a φ22×40 mm can offers substantial capacitance in a reduced footprint for space-constrained designs.
• Designed for Elevated Temperatures: 105 °C rating and 2000‑hour endurance provide predictable aging and performance under sustained thermal stress.
• Measured Ripple Performance: Explicit low- and high-frequency ripple current specifications (1.65 A @120 Hz and 2.475 A @100 kHz) enable selection based on actual operating ripple conditions.
• Reliable Electrical Characteristics: Leakage current defined by I ≤ 3√CV and a specified tan δ limit (applicable to the part’s voltage range) support predictable dissipation and insulation behavior.
• Easy Mechanical Integration: Snap-in radial can package simplifies through-hole mounting and provides durable mechanical retention for heavier power boards.
• Regulatory Compliance: RoHS compliance supports designs targeting regions with restricted substance requirements.
