LAQ2D681MELA40

The LAQ2D681MELA40 is an aluminum electrolytic capacitor from the Nichicon LAQ series featuring a snap‑in terminal (radial can) package. It provides 680 µF capacitance at a 200 V rated voltage with ±20% tolerance and is specified for general‑purpose applications.

Designed for elevated‑temperature operation, this LAQ part supports continuous operation up to 105°C with a rated endurance of 2000 hours, and offers robust ripple handling for smoothing and power conditioning in general‑purpose power applications.

Key Features

• Capacitance & Voltage — 680 µF nominal capacitance with ±20% tolerance, rated at 200 V for medium‑voltage bulk energy storage and filtering.
• High‑Temperature Endurance — Rated for operation from −25°C to +105°C with a guaranteed life of 2000 hours at 105°C under DC bias plus rated ripple current.
• Ripple Current Performance — Handles 1.75 A (rms) at 120 Hz and 2.10 A (rms) at 10 kHz, useful where AC ripple rejection and smoothing are required.
• Low Leakage — Specified leakage current of 1.1 mA, supporting low‑loss operation after voltage application at 20°C.
• Package & Mounting — Snap‑in terminal, radial can (φ25 × 40 mm) for secure PCB mounting and mechanical stability in assemblies.
• Polarized Electrolytic — Polarized design for DC bulk and smoothing applications.

Typical Applications

• General‑purpose power supplies — Bulk smoothing and ripple suppression where 200 V rating and high ripple current capacity are required.
• Industrial equipment — Power conditioning in industrial control and power conversion systems that demand operation up to 105°C for extended durations.
• Power modules and assemblies — Snap‑in radial package enables secure mounting in power assemblies and chassis‑mounted boards.

Unique Advantages

• 200 V rated voltage: Supports higher‑voltage DC applications without overspecifying component voltage.
• High ripple capability: 1.75 A @120 Hz and 2.10 A @10 kHz ratings reduce heating and improve longevity under AC ripple stress.
• 105°C endurance: 2000‑hour life at 105°C provides predictable performance in elevated‑temperature environments.
• Compact snap‑in form factor: φ25 × 40 mm radial can with snap‑in terminals simplifies board layout and mechanical retention.
• Measured low leakage: 1.1 mA specified leakage current supports efficiency and minimizes standby losses after voltage application.
