LAQ2D391MELZ35

The LAQ2D391MELZ35 is a Nichicon LAQ series aluminum electrolytic capacitor in a snap‑in terminal, radial can package. It provides 390 µF capacitance at a 200 V rating with polarized construction and is supplied in tray packing for mass production.

Designed for general purpose applications, this component combines a compact φ22×35 mm can size with specified ripple performance and a 2000‑hour endurance rating at 105°C to meet demanding power and filtering requirements in higher‑voltage designs.

Key Features

• Capacitance & Voltage — 390 µF nominal capacitance with a 200 V rated working voltage and ±20% tolerance.
• Snap‑In Radial Can Package — Snap‑in terminal mounting in a φ22×35 mm (D×L) radial can; supplied in tray packing for production handling.
• Ripple Current Performance — Rated ripple current of 1.35 A at 120 Hz (low frequency) and 1.62 A at 10 kHz (high frequency) for AC stress handling.
• Low Leakage — Specified leakage current of 0.83 mA, measured per product conditions in the datasheet.
• High‑Temperature Endurance — 2000 hours life rating at 105°C under DC bias plus rated ripple current; capacitance and leakage meet endurance criteria after restoration to 20°C.
• Operating Temperature Range — Rated for −25°C to +105°C operation.
• Polarized Component — Electrolytic, polarized design for DC applications where polarity is controlled.
• RoHS Compliant — Meets RoHS requirements as indicated in the product data.

Typical Applications

• General Purpose Systems — Suitable for general purpose applications requiring bulk capacitance and voltage handling in a snap‑in package.
• High‑Voltage DC Circuits — Applicable where a 200 V rated polarized capacitor is required for energy storage or DC smoothing.
• Production Assemblies — Tray packing and snap‑in terminals support automated handling and secure PCB mounting for mass production runs.

Unique Advantages

• 200 V Working Voltage: Enables use in higher‑voltage power designs without exceeding rated limits.
• High‑Temperature Life: 2000 hours at 105°C provides defined endurance for thermal stress scenarios and correlated lifetime planning.
• Dual‑Frequency Ripple Ratings: Specified ripple currents at both 120 Hz and 10 kHz allow designers to assess performance across mains‑frequency and higher‑frequency ripple conditions.
• Compact Snap‑In Form Factor: φ22×35 mm radial can with snap‑in terminals offers a balance of capacitance density and secure PCB mounting for production environments.
• Low Leakage Specification: 0.83 mA leakage current supports applications where low DC leakage is required after voltage application.
• RoHS Compliance: Supports environmental and regulatory requirements for lead‑restricted applications.
