LAQ2D561MELB30ZB

The LAQ2D561MELB30ZB is a snap‑in terminal aluminum electrolytic capacitor from Nichicon’s LAQ series. It delivers 560 µF capacitance at a 200 V rating in a compact φ30×30 mm can, designed for general‑purpose power electronics requiring high ripple handling and robust high‑temperature endurance.

Engineered for equipment operating across fluctuating voltage conditions, this part combines high ripple current capability, a 105°C endurance rating and built‑in safety measures to support reliable bulk energy storage and smoothing in industrial and commercial systems.

Key Features

• Capacitance & Voltage: 560 µF rated capacitance with a 200 V working voltage and ±20% tolerance for bulk filtering on elevated DC rails.
• High‑temperature Endurance: Rated for operation over −25°C to +105°C with a life specification of 2000 hours at 105°C under D.C. bias plus rated ripple current.
• High Ripple Current: Supports 1.6 A ripple at 120 Hz (low frequency) and 1.92 A at 10 kHz (high frequency), suitable for smoothing and decoupling on both line‑frequency and switching sources.
• Low Loss: Tangent of loss angle (tan δ) ≤ 0.20 measured at 20°C, 120 Hz, minimizing dissipation in AC/RF ripple environments.
• Safety Features: Pressure relief vent and series improvements for abnormal overvoltage conditions to reduce risk of hazardous failure modes.
• Package & Mounting: Radial snap‑in terminal can (φ30×30 mm) for secure chassis or PCB mounting; supplied in tray packing for production handling.
• Compliance: RoHS‑compliant construction.

Typical Applications

• Switched‑mode power supplies (SMPS): Bulk smoothing and energy storage on 200 V rails where high ripple current and 105°C endurance are required.
• Industrial power conversion: DC link smoothing and ripple suppression in converters and inverters operating under fluctuating voltages.
• Commercial equipment: Energy buffering and decoupling in machinery and systems where compact, high‑voltage capacitors are needed.

Unique Advantages

• High ripple capability: Handles both low‑ and high‑frequency ripple (1.6 A @ 120 Hz, 1.92 A @ 10 kHz), reducing heating and extending system reliability under switching loads.
• Robust high‑temperature life: 2000 hours at 105°C under rated conditions provides predictable ageing and maintenance planning for high‑temperature deployments.
• Compact high‑voltage form factor: φ30×30 mm case offers high capacitance per volume for designs constrained by space but requiring 200 V rating.
• Snap‑in mounting: Secure terminal retention simplifies mechanical assembly and ensures reliable electrical connection in vibration‑prone environments.
• Safety‑oriented design: Pressure relief vent and improved series safety measures help mitigate risks from abnormal overvoltage events.
• RoHS compliant and production ready: Tray packing and mass‑production status support repeatable procurement and assembly processes.
