LAQ2P331MELB25

The LAQ2P331MELB25 is an aluminum electrolytic capacitor in a snap-in terminal, radial can package designed for general-purpose power applications. It delivers 330 µF at a 220 V rating with polarized construction and a compact footprint for systems requiring bulk capacitance in a smaller case size.

Built to operate across -25°C to 105°C and rated for endurance under D.C. bias plus rated ripple current, this part is targeted at equipment exposed to fluctuating voltages where extended temperature tolerance, safety under abnormal voltage, and reliable ripple handling are required.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance with a 220 V rated voltage for bulk energy storage and smoothing in medium-voltage circuits.
• High Temperature Endurance — Rated operating range from -25°C to 105°C with a specified lifetime of 2000 hours at 105°C when subjected to D.C. bias plus rated ripple current.
• Snap-in Terminal, Radial Can — Snap-in mounting for secure PCB installation and quick assembly in power assemblies.
• Ripple Current Performance — Rated ripple current of 1.2 A at 120 Hz and 1.44 A at 10 kHz, supporting ripple handling across common power frequencies.
• Permissible Abnormal Voltage & Safety — Series-level design includes improved safety features for abnormally excessive voltage and a pressure relief vent designed to operate without flames or dispersion.
• Compact Footprint — Smaller-sized case with dimensions L: 2.5 × D: 3 cm, suitable where board space is constrained.
• Electrical Characteristics — Polarized device with ±20% capacitance tolerance and leakage/impedance characteristics specified per the LAQ series.

Typical Applications

• General-purpose power filtering — Bulk smoothing and energy storage in power conversion and distribution circuits requiring 220 V-rated capacitance.
• Equipment in fluctuating-voltage environments — Designed for use in systems where voltage variations occur, leveraging series safety features for abnormal voltages.
• Industrial and commercial power assemblies — Suitable for assemblies that need compact, high-temperature-capable capacitors with reliable ripple performance.

Unique Advantages

• High-temperature reliability: Rated to 105°C with a 2000-hour endurance specification under rated ripple and bias, enabling durable operation in hot operating environments.
• Designed for abnormal voltage scenarios: Series-level safety features and a pressure relief vent reduce risk in instances of excessive voltage.
• Strong ripple handling: Specified ripple currents at both 120 Hz and 10 kHz provide predictable performance across low- and high-frequency ripple conditions.
• Secure snap-in mounting: Snap-in terminals provide robust mechanical retention for power PCBs and simplify assembly.
• Compact sizing: Smaller case dimensions (L: 2.5 × D: 3 cm) help conserve board space while delivering 330 µF at 220 V.
• Manufacturer-backed series design: Part of Nichicon’s LAQ series, offering series-level specifications such as RoHS compliance and defined endurance/leakage limits.
