LGN2Z681MELZ35

The LGN2Z681MELZ35 is a snap‑in terminal, large‑can aluminum electrolytic capacitor from Nichicon’s LGN series. It provides 680 µF capacitance at a 180 V rating in a compact φ22 × 35 mm can designed for snap‑in PCB mounting.

Built for general‑purpose power electronics, this part combines high ripple handling, extended endurance at elevated temperature, and RoHS compliance to support reliable AC and DC smoothing, bulk energy storage, and power conversion functions.

Key Features

• Capacitance and Voltage — 680 µF nominal capacitance rated at 180 V for bulk filtering and energy storage in medium‑voltage circuits.
• High Ripple Capability — Low‑frequency ripple current 1.7 A (120 Hz) and high‑frequency ripple current 2.55 A (100 kHz) to support demanding ripple environments.
• High Temperature Endurance — Rated endurance of 3000 hours at 105 °C when subjected to rated ripple current and DC bias, supporting long life under elevated operating temperatures.
• Loss Characteristics — Tangent of loss angle (tan δ) max 0.15 measured at 20 °C, 120 Hz, for predictable dissipation performance.
• Leakage Current — Specified leakage current of 1040 µA to allow accurate system leakage budgeting.
• Mechanical and Mounting — Radial, snap‑in can package (φ22 × 35 mm) for secure snap‑in PCB mounting and straightforward assembly; packaged in trays for production handling.
• Wide Operating Range — Operational temperature range from −40 °C to 105 °C for use across varied thermal environments.
• Compliance and Availability — RoHS compliant and in mass production for predictable sourcing and regulatory alignment.

Typical Applications

• Industrial Power Supplies — Bulk filtering and smoothing at 180 V where 680 µF capacitance and 1.7 A to 2.55 A ripple handling stabilize supply rails.
• Power Conversion Modules — DC link and energy storage in converters and inverters that require high ripple tolerance and 105 °C endurance.
• Motor Drives and Controls — DC bus smoothing and transient energy buffering in motor control electronics operating across wide temperature ranges.

Unique Advantages

• Long High‑Temperature Life: 3000 hours endurance at 105 °C provides extended service life in thermally stressed applications.
• Strong Ripple Performance: Combined low‑ and high‑frequency ripple ratings (1.7 A @120 Hz, 2.55 A @100 kHz) reduce the need for parallel components to handle AC stress.
• Compact Snap‑in Form Factor: φ22 × 35 mm snap‑in can offers a smaller case footprint while enabling robust mechanical retention on the PCB.
• Predictable Electrical Losses: tan δ specified at 0.15 (20 °C, 120 Hz) aids thermal and efficiency calculations during design.
• Production‑Ready Packaging: Tray packing and mass‑production status simplify procurement and assembly planning.
• RoHS Compliant: Meets RoHS directive requirements for environmentally regulated designs.
