LAQ2D681MELC25ZB

The LAQ2D681MELC25ZB from Nichicon is a snap‑in terminal aluminum electrolytic capacitor in the LAQ series, rated at 680 µF and 200 V. It is a polarized, radial can type designed for general‑purpose electronic applications that require high capacitance and sustained performance at elevated temperatures.

Key performance attributes include a 2000‑hour endurance at 105°C, specified ripple current ratings for both low and high frequency, and a compact φ35 × 25 mm form factor supplied in tray packaging for mass production environments.

Key Features

• Capacitance & Voltage — 680 µF nominal capacitance with a 200 V rated voltage and ±20% tolerance.
• Ripple Current Performance — Rated ripple current of 1.75 A at 120 Hz (low frequency) and 2.1 A at 10 kHz (high frequency) to support AC ripple on DC rails.
• Endurance & Temperature Range — 2000 hours life at 105°C with operating temperature range of −25°C to +105°C, as specified for LAQ series endurance testing.
• Leakage & Loss — Specified leakage current of 1100 µA; tan δ specified in the series datasheet for stability at 120 Hz and 20°C.
• Package & Mounting — Snap‑in radial can construction (φ35 × 25 mm) for secure board mounting and straightforward assembly.
• Safety Design — Pressure relief vent behavior specified in the LAQ series datasheet to avoid hazardous failure modes under abnormal conditions.
• Production‑ready Packaging — Supplied in tray packing suitable for volume manufacturing and automated handling.

Typical Applications

• General Purpose Electronics — Designed for applications requiring 680 µF at 200 V in a snap‑in radial can format.
• Power Rail Support — Suitable where defined ripple current handling and leakage characteristics are required across −25°C to +105°C.
• High‑Temperature Operation — Applicable to designs that need verified endurance at elevated temperatures (2000 hours at 105°C).

Unique Advantages

• High Voltage Rating: 200 V nominal rating supports higher voltage DC rail designs without series stacking.
• Substantial Capacitance: 680 µF provides significant bulk energy storage in a compact φ35 × 25 mm can.
• Dual‑Frequency Ripple Capability: Separate ripple current specifications for 120 Hz (1.75 A) and 10 kHz (2.1 A) indicate validated performance across typical low and high frequency ripple scenarios.
• Designed for Elevated Temperatures: 2000‑hour endurance at 105°C supports extended reliability in thermally demanding environments.
• Assembly‑Friendly Snap‑In Package: Radial snap‑in terminals enable robust mechanical mounting and are compatible with common through‑hole assembly processes.
• Production Packaging: Tray packing and mass production availability streamline procurement and volume assembly workflows.
