LAK2D331MELB25

The LAK2D331MELB25 is a snap-in terminal aluminum electrolytic capacitor from Nichicon’s LAK series. It delivers 330 µF capacitance at a 200 V rating in a radial can (φ30 × 25 mm) with polarized snap-in mounting.

Designed for general-purpose use, this capacitor combines high-temperature endurance and safety features—making it suitable for equipment operating in environments with voltage fluctuation and elevated thermal stress.

Key Features

• Capacitance & Voltage — 330 µF rated capacitance with a 200 V working voltage and a tolerance of ±20% (120 Hz, 20°C).
• High-Temperature Endurance — Rated for operation from −25°C to +105°C with a guaranteed operational lifetime of 2000 hours at 105°C when subjected to rated ripple and D.C. bias.
• Loss and Leakage Characteristics — Tangent of loss angle (tan δ) 0.20 max at 120 Hz and 20°C; leakage current meets I ≤ 3√CV (μA) after 5 minutes at 20°C as specified in the datasheet.
• Ripple Current Capability — Specified ripple handling of 1.05 A at 120 Hz and 1.26 A at 10 kHz for robust performance under AC stress.
• Package & Mounting — Radial can, snap-in terminal type, physical dimensions φ30 × 25 mm for secure PCB mounting and space-efficient placement.
• Safety Features — Series-level design includes improved safety measures for abnormally excessive voltage and a pressure relief vent to mitigate hazardous conditions.
• Environmental Compliance — RoHS directive compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• General Purpose Equipment — Suited for a wide range of general-purpose power and electronic equipment that require 330 µF at 200 V and operation within −25°C to +105°C.
• Voltage-Fluctuating Environments — The LAK series is described as ideally suited for equipment used in areas with voltage fluctuation due to its extended voltage handling and safety measures for abnormal voltage.
• High-Temperature, High-Ripple Modules — Withstanding 2000 hours application of rated ripple current at 105°C makes this part appropriate where sustained thermal and ripple stress are expected.

Unique Advantages

• Proven Endurance: 2000 hours at 105°C under rated ripple and D.C. bias verifies long-term stability for demanding thermal conditions.
• Measurable Ripple Performance: Rated ripple currents at both 120 Hz and 10 kHz give clear, application-relevant data for power design trade-offs.
• Designed for Abnormal Voltage Safety: Series-level improvements for abnormally excessive voltage and a pressure relief vent reduce risk in fluctuating-voltage environments.
• Clear Electrical Specifications: Explicit tan δ, leakage current formula, and tolerance data support reliable design calculations and margining.
• Regulatory Compliance: RoHS compliance supports use in products that must meet current environmental directives.
