LAQ2D391MELA30ZB

The LAQ2D391MELA30ZB from Nichicon is a snap‑in terminal aluminum electrolytic capacitor in the LAQ series, rated 200 V with 390 µF nominal capacitance and ±20% tolerance. It is a radial can, snap‑in package designed for general‑purpose power electronics where compact high‑voltage bulk capacitance and robust ripple handling are required.

With an operating range from −25°C to +105°C and a specified 2000‑hour endurance at 105°C, this part targets applications that need stable capacitance, controlled leakage, and sustained ripple current performance on 200 V rails.

Key Features

• Capacitance & Tolerance — 390 µF nominal with ±20% tolerance at 120 Hz, 20°C, providing reliable bulk energy storage for 200 V systems.
• Rated Voltage — 200 V DC rating suitable for mid‑voltage power rails and energy storage stages.
• Snap‑In Radial Package — Snap‑in terminal type in a radial can package (φ25 × 30 mm), enabling secure board mounting and straightforward assembly.
• Ripple Current Capability — 1.35 A at 120 Hz (low frequency) and 1.62 A at 10 kHz (high frequency), supporting both mains‑frequency and switching ripple demands.
• Low Leakage — Specified leakage current of 0.83 mA (after rated voltage applied), helping maintain efficiency and predictable discharge behavior.
• High Temperature Endurance — Rated for 2000 hours at 105°C under D.C. bias plus rated ripple current, supporting durable operation in elevated temperature environments.
• Polarized Design — Polarized electrolytic suited for DC bulk and smoothing applications.
• Mass Production & Packaging — Tray packing, available for volume production and automated handling.

Typical Applications

• Industrial Power Supplies — Bulk smoothing and energy storage on 200 V rails where 390 µF capacitance and 1.35 A ripple at 120 Hz improve voltage stability under load.
• Switch‑Mode Power Supplies (SMPS) — DC link and output filter use, leveraging the 1.62 A ripple rating at 10 kHz for switching frequency ripple suppression.
• Motor Drives & Inverters — DC bus buffering and transient energy support on mid‑voltage drives, benefiting from the 200 V rating and 2000 h endurance at 105°C.
• General Purpose Industrial Electronics — Applications requiring compact high‑voltage capacitance with controlled leakage and long‑term thermal endurance.

Unique Advantages

• 200 V Energy Storage: 390 µF at 200 V provides substantial bulk capacitance for mid‑voltage rails without a large footprint (φ25 × 30 mm).
• Dual‑Band Ripple Performance: Rated ripple current values at 120 Hz and 10 kHz allow designers to address both mains and high‑frequency switching ripple with a single component.
• Designed for Elevated Temperatures: 2000‑hour endurance at 105°C under bias delivers predictable long‑term performance in hot operating environments.
• Low Standby Leakage: 0.83 mA leakage current after voltage application reduces standby losses and improves predictable discharge characteristics.
• Robust Mounting: Snap‑in radial can simplifies mechanical retention and PCB assembly for higher‑volume production runs.
• Manufacturer Series Consistency: Part of the Nichicon LAQ series, providing consistent family specifications for system design and inventory management.
