LAQ2P681MELB40

The LAQ2P681MELB40 is a 680 µF, 220 V aluminum electrolytic capacitor from Nichicon's LAQ series with a snap‑in terminal configuration. Designed for general‑purpose power applications, it provides high ripple handling and long endurance in a compact radial can package.

This snap‑in type capacitor is intended for use where robust DC bias and ripple performance, reliable mounting, and extended elevated‑temperature life are required. It is available in tray packing and is in mass production.

Key Features

• Capacitance and Voltage — 680 µF nominal capacitance with ±20% tolerance and a 220 V rated voltage, suitable for bulk energy storage and decoupling in medium‑voltage circuits.
• Ripple Current Performance — Rated ripple current of 1.75 A at 120 Hz (low frequency) and 2.10 A at 10 kHz (high frequency) to handle AC ripple under DC bias conditions.
• Thermal and Endurance — Rated for operation from −25°C to +105°C with an endurance of 2000 hours at 105°C when subjected to DC bias plus rated ripple current.
• Leakage Current — Specified leakage current of 1160 µA (measured after voltage application conditions), supporting stable performance in long‑term energized circuits.
• Package and Mounting — Snap‑in radial can package (φ30 × 40 mm length) for secure board mounting and simplified assembly.
• Safety Design — Built with a pressure relief vent to mitigate abnormal conditions without dangerous flame or dispersion of parts.

Typical Applications

• Power supply smoothing — Bulk energy storage and ripple filtering in power converters and supplies where 220 V rating and high ripple current capability are required.
• Industrial electronics — General‑purpose DC filtering and decoupling in industrial control and power systems operating up to 105°C.
• High‑density assemblies — Compact radial snap‑in form factor for applications requiring secure through‑hole mounting and tray packing for production assembly.

Unique Advantages

• High voltage capability: 220 V rating supports higher DC link and intermediate bus voltages compared with lower‑voltage electrolytics.
• Elevated temperature endurance: 2000 hours at 105°C under rated conditions provides predictable aging and reliability for demanding thermal environments.
• Robust ripple handling: Dual ripple current specifications (120 Hz and 10 kHz) allow designers to size the capacitor against both low‑ and high‑frequency ripple sources.
• Secure mechanical mounting: Snap‑in radial can simplifies board installation and improves mechanical retention in through‑hole assemblies.
• Controlled leakage: Specified leakage current value enables predictable standby and energized behavior in power circuits.
• Production ready: Tray packing and mass production availability streamline procurement and manufacturing logistics.
