LAQ2D331MELZ30ZB

The LAQ2D331MELZ30ZB is a Nichicon LAQ series aluminum electrolytic capacitor in a snap‑in terminal can, rated 330 µF ±20% at 200 V. Designed for general‑purpose power applications, it combines high DC voltage rating with robust ripple handling and long endurance for sustained operation in commercial and industrial equipment.

Key attributes include a 2000‑hour endurance at 105 °C, low leakage current, and snap‑in mounting in a compact φ22 × 30 mm package—features that support reliable filtering and energy storage in power subsystems.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance with a 200 V rated voltage and ±20% tolerance at 120 Hz, 20 °C.
• Ripple Current Performance — Handles 1.2 A (120 Hz) low‑frequency ripple and 1.44 A (10 kHz) high‑frequency ripple, allowing effective smoothing under varying switching conditions.
• Low Leakage — Specified leakage current of 0.77 mA for stable DC performance after voltage application.
• Endurance — 2000 hours rated life at 105 °C under DC bias plus rated ripple current, with capacitance change, tan δ, and leakage current meeting the LAQ series endurance limits.
• Temperature Range — Operational from −25 °C to +105 °C to accommodate typical industrial and commercial temperature environments.
• Package & Mounting — Snap‑in radial can package (φ22 × 30 mm) for secure, board‑mount installation; supplied in tray packing for production workflows.
• Polarized Device — Polarized construction for DC power applications where correct polarity is maintained.

Typical Applications

• Power supply filtering: Bulk smoothing and decoupling in switch‑mode and linear power supplies, leveraging the 200 V rating and high ripple current capability.
• Industrial power electronics: Energy buffering and filtering in industrial converters and controls where elevated voltage and sustained operating temperature are required.
• Commercial UPS and standby systems: DC link and reservoir capacitor use for energy storage and transient absorption in commercial uninterruptible power systems.

Unique Advantages

• High DC voltage capability: 200 V rating supports higher‑voltage power rails without additional series components.
• Robust ripple handling: 1.2 A (120 Hz) and 1.44 A (10 kHz) ripple ratings reduce temperature rise and extend operational stability under switching loads.
• Long endurance at elevated temperature: 2000 h at 105 °C provides clear life‑time expectation for designs deployed in warm environments.
• Compact snap‑in form factor: φ22 × 30 mm radial can with snap‑in terminals simplifies PCB integration and mechanical retention for high‑volume assembly.
• Low leakage current: 0.77 mA leakage supports DC stability and minimizes standby losses in power circuits.
• Production‑friendly packaging: Tray packing and mass‑production readiness streamline procurement and assembly for volume manufacturing.
