LAQ2P391MELB30

The LAQ2P391MELB30 is a Nichicon aluminum electrolytic capacitor in a snap-in terminal format, rated 220 V with 390 µF nominal capacitance and ±20% tolerance. It is specified for general-purpose applications and mass-production assembly, offered in a compact φ30 × 30 mm can with tray packing.

Designed for applications needing elevated operating temperature capability and sustained ripple handling, this polarized capacitor combines a 2000-hour endurance rating at 105°C with defined low- and high-frequency ripple current performance.

Key Features

• Capacitance & Tolerance — 390 µF nominal capacitance with ±20% tolerance (measured at 120 Hz, 20°C).
• Rated Voltage — 220 V DC rating for mid-voltage circuit requirements.
• Mounting & Package — Snap-in radial can package (φ30 × 30 mm; L: 3 × D: 3 cm) optimized for chassis or PCB snap-in installation; supplied in tray packing for production workflows.
• Ripple Current Capability — 1.35 A at 120 Hz (low frequency) and 1.62 A at 100 kHz (high frequency), enabling continuous operation under AC ripple conditions.
• Operating Temperature & Endurance — Rated for −25°C to +105°C with a 2000-hour endurance specification at 105°C under DC bias plus rated ripple current.
• Leakage & Dissipation — Specified leakage current of 870 µA and tangent of loss angle (tan δ) up to 0.20 at 20°C and 120 Hz, supporting predictable dissipation characteristics.
• Polarized Construction & Safety — Polarized electrolytic design with a pressure relief vent that operates to avoid dangerous conditions under specified abnormal events.
• Production Ready — Listed as mass production status and packaged for tray-based handling to support volume assembly processes.

Typical Applications

• General-purpose electronics — Bulk capacitance in general-purpose designs requiring a 220 V, 390 µF electrolytic solution.
• General-purpose assemblies with snap-in mounting — Chassis or board assemblies where snap-in installation and tray packing support efficient production.
• General-purpose designs with ripple demands — Circuits that require defined ripple current performance at both low and high frequencies.

Unique Advantages

• Voltage and capacitance combination: 220 V rating with 390 µF provides substantial stored energy for mid-voltage general-purpose applications.
• Dual-frequency ripple specification: Explicit ripple ratings at 120 Hz and 100 kHz allow designers to size components for both mains-frequency and higher-frequency ripple conditions.
• High-temperature endurance: 2000 hours at 105°C gives a defined life expectation under elevated temperature and DC bias plus ripple current.
• Predictable dissipation and leakage: tanδ ≤ 0.20 and specified leakage current (870 µA) support thermal and leakage budgeting in designs.
• Production-friendly packaging: Tray packing and snap-in format simplify handling and mounting in volume assembly environments.
• Built-in safety venting: Pressure relief venting reduces risk of hazardous failure modes under specified abnormal conditions.
