LAQ2D331MELA25ZB

The LAQ2D331MELA25ZB is a 330 µF, 200 V aluminum electrolytic capacitor in Nichicon’s LAQ series featuring a snap-in terminal radial can. It is specified for general purpose use and provides a compact, high-voltage electrolytic solution in a φ25 × 25 mm package.

Designed for applications requiring reliable high-voltage capacitance, this part delivers defined ripple-handling, leakage, and endurance performance across a −25°C to +105°C operating range.

Key Features

• Capacitance and Tolerance: 330 µF nominal capacitance with ±20% tolerance (measured at 120 Hz, 20°C).
• Rated Voltage: 200 V DC rating for higher-voltage circuit requirements.
• Ripple Current Performance: 1.20 A rated ripple current at 120 Hz and 1.44 A at 10 kHz, enabling effective AC ripple handling within the specified frequencies.
• Low Leakage Current: Specified leakage current of 0.77 mA after voltage application, consistent with measured product values.
• Temperature Range and Endurance: Operates from −25°C to +105°C with a rated lifetime of 2000 hours at 105°C under DC bias plus rated ripple current; after this endurance test, capacitance change remains within ±20%, tan δ is 200% or less of initial value, and leakage current is at or below the initial specified value.
• Package and Mounting: Radial, snap-in can package (φ25 × 25 mm) for secure chassis or board mounting and mass-production tray packing.
• Safety Feature: Pressure relief vent design to operate under abnormal conditions without creating dangerous outcomes such as flames or case dispersion.
• Polarized Electrolytic: Polarized construction for DC applications where orientation is critical.

Typical Applications

• General Purpose Electronics: For general purpose circuits requiring a 200 V, 330 µF snap-in electrolytic capacitor in a compact package.
• Power Modules and Assemblies: As a high-voltage bulk or smoothing capacitor where defined ripple current handling and endurance at elevated temperature are required.
• Industrial Equipment: Where a durable, polarized aluminum electrolytic with a 2000-hour endurance at 105°C is needed for long-term operation.

Unique Advantages

• High-voltage capability: 200 V rating enables use in circuits with elevated DC voltages while maintaining compact φ25 × 25 mm dimensions.
• Measured ripple specifications: Defined ripple current ratings at both low (120 Hz) and high (10 kHz) frequencies support predictable thermal and performance behavior under AC stress.
• Endurance at high temperature: 2000 hours at 105°C under rated conditions with specified post-test limits gives designers quantifiable long-term performance metrics.
• Controlled leakage: 0.77 mA specified leakage current supports predictable standby and idle behavior in DC circuits.
• Snap-in package for production: Radial snap-in can and tray packing simplify handling and installation in high-volume assembly environments.
• Built-in safety venting: Pressure relief vent reduces risk under abnormal conditions without causing dangerous outcomes.
