LAQ2D681MELC25

The LAQ2D681MELC25 from Nichicon is a snap-in terminal aluminum electrolytic capacitor in the LAQ series, rated at 680 µF and 200 V. Designed for general-purpose applications, it delivers high-voltage capacitance in a compact radial can with snap-in mounting and tray packing for production environments.

This component combines a 105°C permissible operating window and a 2000-hour endurance rating at 105°C with robust ripple handling, making it suitable where stable bulk capacitance and long-term thermal endurance are required within the specified data sheet limits.

Key Features

• Capacitance & Voltage — 680 µF capacitance at a 200 V rated voltage with ±20% tolerance, providing predictable bulk energy storage within the specified tolerance band.
• High Temperature Endurance — Rated for continuous operation from -25°C to +105°C with a specified endurance of 2000 hours at 105°C under rated conditions.
• Ripple Current Capability — Handles 1.75 A (rms) at low frequency (120 Hz) and 2.10 A (rms) at high frequency (10 kHz), supporting applications with moderate ripple loads.
• Leakage Current — Specified leakage current of 1100 µA, measured in accordance with the product’s test conditions.
• Package & Mounting — Snap-in radial can package (φ35 × 25 mm) for secure PCB mounting and automated assembly; supplied in tray packing for mass production.
• Polarized Design — Polarized aluminum electrolytic construction for use where polarity is observed.

Typical Applications

• General-purpose power electronics — Bulk capacitance and smoothing in power supplies and power-conditioning circuits within the 200 V rating.
• Industrial equipment — Energy storage and ripple filtering in industrial control and power modules requiring 105°C endurance.
• Commercial power systems — Support for higher-voltage DC bus and secondary filtering where compact, snap-in radial cans are preferred.

Unique Advantages

• High-voltage capability: 200 V rating enables use in higher-voltage DC circuits while maintaining 680 µF bulk capacitance.
• Temperature-hardened design: Rated operation to 105°C with a 2000-hour endurance, offering predictable long-term performance in elevated-temperature environments.
• Robust ripple handling: Separate ripple ratings for low and high frequency (1.75 A at 120 Hz, 2.10 A at 10 kHz) allow designers to assess suitability across a range of switching environments.
• Production-ready packaging: Tray packing suited for mass production streamlines handling and assembly for volume manufacturing.
• Compact radial form factor: φ35 × 25 mm snap-in can provides a space-efficient solution for boards requiring secure mechanical retention.
