LAK2D391MELA30ZB

The LAK2D391MELA30ZB is a snap‑in terminal aluminum electrolytic capacitor from Nichicon's LAK series. It is a polarized, radial can snap‑in device rated at 390 µF and 200 V, designed for general purpose applications requiring high ripple handling and extended endurance at elevated temperature.

Key value propositions include robust ripple current capability, 2000 hours endurance at 105°C, and safety features for abnormal voltage conditions — making it suitable for equipment operating in environments with voltage fluctuation.

Key Features

• Capacitance & Voltage — 390 µF nominal capacitance with a 200 V rated voltage and ±20% tolerance, suitable where mid‑range bulk capacitance at 200 V is required.
• Snap‑in Radial Can Package — Snap‑in terminal mounting in a radial can (D: 25 mm × L: 30 mm) for secure PCB installation and mechanical stability; supplied in tray packing for production assembly.
• High Ripple Current Capability — Rated ripple current of 1.2 A at 120 Hz (low frequency) and 1.44 A at 10 kHz (high frequency) for sustained AC loading conditions.
• Endurance at Elevated Temperature — 2000 hours life specification at 105°C when subjected to rated ripple and DC bias, enabling reliable operation in high‑temperature environments.
• Leakage and Dissipation — Specified leakage current of 830 µA and a tangent of loss angle (tan δ) up to 0.20 max at 20°C/120 Hz for predictable electrical behavior.
• Safety and Abnormal Voltage Handling — LAK series improvements include enhanced safety features for abnormally excessive voltage and a pressure relief vent designed to operate without flames or dispersion under test conditions.
• Environmental Compliance — RoHS compliant formulation for regulatory compatibility.

Typical Applications

• General Purpose Power Equipment — Used where a 390 µF, 200 V snap‑in capacitor is required for bulk capacitance in power circuits within equipment exposed to fluctuating voltages.
• High‑Temperature Environments — Applications that require sustained performance at up to 105°C, benefiting from the 2000 hour endurance rating.
• High Ripple Current Circuits — Circuits that impose continuous ripple stress where the specified 1.2 A (120 Hz) and 1.44 A (10 kHz) ratings are needed.

Unique Advantages

• Extended Endurance at 105°C — 2000 hours rated life under rated ripple and DC bias provides predictable long‑term performance in hot operating conditions.
• Robust Ripple Handling — Defined ripple current ratings at both low and high frequencies support designs with significant AC stress across the capacitor.
• Designed for Voltage Fluctuation — Series features and construction target safer behavior under abnormally excessive voltage, helping mitigate risk in variable supply environments.
• Snap‑in Mounting for Production — Radial snap‑in package and tray packing streamline assembly for high‑volume manufacturing.
• Predictable Electrical Characteristics — Specified tan δ (0.20 max at 20°C/120 Hz) and a measured leakage current value aid in margining and thermal design.
• Regulatory Compliance — RoHS conformity for use in regulated product lines.
