LGG2Z681MELZ35

The LGG2Z681MELZ35 is a snap‑in terminal aluminum electrolytic capacitor from Nichicon’s LGG series. It delivers 680 µF of capacitance at a 180 V rating in a compact φ22 × 35 mm radial can designed for high‑temperature operation up to 105°C.

Built for general‑purpose power applications, this part combines high ripple handling, low leakage, and a 2000‑hour endurance at 105°C to support reliable DC bus filtering and energy storage in dense assemblies where a smaller snap‑in case is required.

Key Features

• Capacitance & Voltage: 680 µF rated capacitance with a 180 V working voltage and ±20% tolerance for predictable bulk energy storage.
• High ripple capability: Supports 1.7 A ripple at 120 Hz and 2.55 A ripple at 100 kHz, enabling effective AC ripple smoothing across low and high frequency ranges.
• Controlled leakage: Specified leakage current of 1.04 mA, supporting stable long‑term performance after application of rated voltage.
• Thermal and endurance rating: Operates from −40°C to +105°C with a 2000 hour endurance specification at 105°C under rated conditions.
• Compact snap‑in package: Radial, can‑snap‑in mounting in a φ22 × 35 mm package for reliable board retention and simplified assembly (tray packing, mass production status).
• Polarized design & RoHS compliant: Polarized electrolytic construction suitable for DC applications and compliant with RoHS requirements.
• Series design note: LGG series offers an ultra‑smaller‑sized 105°C snap‑in option, noted as one rank smaller than the LGN series for space‑constrained designs.

Typical Applications

• General‑purpose power filtering — Bulk capacitance and rated voltage support smoothing and energy storage in standard DC power rails.
• DC bus decoupling — High ripple current capability at both 120 Hz and 100 kHz helps suppress AC ripple on intermediate DC link buses.
• Embedded power modules — Compact φ22 × 35 mm snap‑in package fits tighter layouts while providing required capacitance and thermal endurance.

Unique Advantages

• Space‑saving snap‑in form factor: One rank smaller than LGN series enables downsized power assemblies without foregoing capacitance.
• Wide operating temperature range: −40°C to +105°C operation with 2000 hour endurance at 105°C provides predictable performance in elevated temperature environments.
• Dual‑frequency ripple resilience: Rated ripple currents at 120 Hz and 100 kHz offer designers flexibility across low and high frequency filtering needs.
• Manufacturing readiness: Tray packing and mass production availability support volume assembly workflows and consistent supply.
• Regulatory compliance: RoHS‑compliant construction aligns with common environmental requirements for commercial equipment.
