LAQ2G330MELZ25ZB

The LAQ2G330MELZ25ZB is a snap-in terminal aluminum electrolytic capacitor from Nichicon’s LAQ series. It provides a 33 µF capacitance at a 400 V rating in a compact φ22 × 25 mm radial can with a snap-in mounting style.

Designed for general-purpose use, this capacitor combines high-voltage capability, defined ripple handling at both low and high frequencies, and a 2000-hour endurance at 105°C to support reliable performance in equipment that requires robust DC energy storage and decoupling.

Key Features

• Capacitance & tolerance — 33 µF nominal with ±20% tolerance at 120 Hz, 20°C.
• Rated voltage — 400 V DC rating for high-voltage applications within its class.
• Ripple performance — Rated ripple current of 250 mA at 120 Hz (low frequency) and 287.5 mA at 10 kHz (high frequency) to support AC ripple and smoothing duties.
• Leakage current — Specified leakage current of 340 µA (after standard voltage application conditions).
• Thermal and endurance — Operating temperature range −25°C to +105°C with endurance of 2000 hours at 105°C under rated conditions.
• Package & mounting — Radial, can-type snap-in terminals in a compact φ22 × 25 mm form factor (L: 25 mm × D: 22 mm) intended for tray packing and mass production.
• Safety — Series construction includes a pressure relief vent designed to operate without hazardous outcomes under abnormal conditions.
• Polarized design — Polarized electrolytic capacitor for DC applications requiring correct polarity handling.

Typical Applications

• General-purpose electronics — Suited to general-purpose circuits that require a 400 V, snap-in electrolytic capacitor for energy storage and smoothing.
• High-voltage DC modules — Applicable where compact, high-voltage filtering components with specified ripple handling and 2000 h endurance at 105°C are needed.
• Panel- and chassis-mounted assemblies — Snap-in radial can package (φ22 × 25 mm) for robust mechanical retention in tray-packed production assemblies.

Unique Advantages

• High-voltage capability: 400 V rating allows usage in higher-voltage DC circuits without up-rating multiple components.
• Defined ripple handling: Explicit ripple current ratings at both 120 Hz and 10 kHz give designers measurable limits for low- and high-frequency ripple environments.
• Endurance at elevated temperature: 2000 hours at 105°C provides predictable long-term performance for thermally demanding applications.
• Compact snap-in form factor: φ22 × 25 mm radial can with snap-in terminals simplifies board retention and assembly in mass-production environments.
• Clear electrical specs: Specified leakage current (340 µA) and ±20% capacitance tolerance enable accurate margining during system design.
• Safety venting: Built-in pressure relief vent reduces the risk of dangerous failure modes under abnormal conditions.
