LAQ2P331MELB25ZB

The LAQ2P331MELB25ZB is a Nichicon LAQ series aluminum electrolytic capacitor in a snap-in terminal configuration. It provides 330 µF capacitance at a 220 V rating in a compact φ30 × 25 mm can, targeted for general-purpose power applications that require high ripple handling and extended endurance.

Built for applications exposed to voltage fluctuation and elevated operating temperatures, this part combines a high-voltage rating, measurable ripple current capability across low and high frequencies, and a 2000-hour endurance at 105°C for reliable long-term performance.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance with ±20% tolerance and a 220 V rated voltage for high-voltage smoothing and energy-storage roles.
• Ripple Current Performance — Rated for 1.2 A ripple at 120 Hz and 1.44 A ripple at 10 kHz, supporting both low-frequency and higher-frequency filtering tasks.
• High-Temperature Endurance — Designed for 2000 hours of operation at 105°C under rated conditions, enabling reliable performance in thermally demanding environments.
• Low Leakage — Specified leakage current of 800 µA to control standby losses and maintain predictable behavior in DC circuits.
• Snap-In Radial Can Package — Snap-in terminal mounting simplifies board assembly for power modules; package is specified as radial, can - snap-in with tray packing for mass-production handling.
• Operating Range & Safety — Rated for operation from −25°C to 105°C and incorporates safety features (pressure relief vent) intended to mitigate hazardous conditions under abnormal voltage.
• Series Compliance — LAQ series is stated as compliant to RoHS directives, aligning with common environmental requirements.

Typical Applications

• Power supply filtering — Smoothing and bulk filtering in AC/DC and DC/DC power supplies operating around 220 V where both low- and high-frequency ripple attenuation are required.
• Industrial equipment — DC-link/filtering in industrial control and equipment that experience voltage fluctuation and require capacitors rated for elevated temperatures and long life.
• General-purpose power electronics — Use in general-purpose assemblies and power modules where a compact, high-voltage electrolytic capacitor with snap-in mounting is preferred.

Unique Advantages

• High ripple-handling capability: Dual ripple ratings (1.2 A at 120 Hz, 1.44 A at 10 kHz) support effective filtering across a range of switching frequencies.
• Extended high-temperature life: 2000 hours at 105°C provides predictable ageing characteristics for designs exposed to elevated ambient temperatures.
• Compact, serviceable package: φ30 × 25 mm snap-in can reduces board footprint while enabling straightforward insertion and secure electrical connection for mass-production assembly.
• Controlled leakage: Specified 800 µA leakage current supports stable DC performance and predictable system power budgets.
• Safety features: Pressure relief vent design reduces the risk of dangerous failure modes under abnormal voltage conditions.
• Series-level environmental compliance: LAQ series RoHS compliance supports deployment in environments with regulatory requirements for restricted substances.
