LAQ2P391MELA35

The LAQ2P391MELA35 is a Nichicon LAQ series aluminum electrolytic capacitor in a snap-in, radial can package designed for general-purpose power applications. It provides 390 µF capacitance at a 220 V rating with a compact φ25 × 35 mm can and a snap-in mounting style for robust board retention.

Engineered for 105°C operation and endurance, this part delivers high ripple handling and controlled leakage for applications requiring stabilized DC filtering and energy buffering in commercial and industrial equipment.

Key Features

• Capacitance & Tolerance — 390 µF nominal capacitance with ±20% tolerance (measured at 120 Hz, 20°C), providing predictable bulk capacitance for power filtering and decoupling.
• Rated Voltage — 220 V DC rated voltage suitable for higher-voltage power rails and bulk energy storage.
• High Temperature Endurance — Specified lifetime of 2000 hours at 105°C; meets endurance criteria after DC bias plus rated ripple current is applied and parts are returned to 20°C.
• Ripple Current Performance — 1.35 A (120 Hz) low-frequency ripple current and 1.62 A (10 kHz) high-frequency ripple current to support smoothing under AC-to-DC and switching conditions.
• Low Leakage — Typical leakage current 0.87 mA after rated-voltage application, supporting low standby loss and improved power efficiency.
• Package & Mounting — Snap-in terminal radial can (φ25 × 35 mm) for secure mechanical mounting and straightforward through-hole assembly; tray packing for volume production handling.
• Operating Temperature Range — Rated for −25°C to +105°C to accommodate a wide range of commercial and industrial ambient conditions.

Typical Applications

• Power Supply Filtering — Bulk smoothing and decoupling on medium-voltage DC rails where 220 V rating and 390 µF capacitance provide energy reserve and ripple reduction.
• Industrial Power Electronics — Energy buffering and ripple handling in industrial converters and control equipment that operate within −25°C to +105°C.
• Commercial Equipment — General-purpose DC link and smoothing capacitor for commercial devices requiring reliable long-term operation at elevated temperatures.

Unique Advantages

• High Voltage Capability: 220 V rating enables use on higher-voltage rails without up-rating multiple lower-voltage parts.
• Robust Ripple Handling: Specified ripple currents at both low (1.35 A) and high (1.62 A) frequencies reduce heating and extend operational stability under ripple stress.
• Long High‑Temperature Life: 2000-hour endurance at 105°C supports designs requiring sustained elevated-temperature reliability.
• Compact Snap-In Package: φ25 × 35 mm radial can with snap-in terminals offers a space-efficient form factor and secure board retention for through-hole assembly.
• Controlled Leakage: Low leakage current (0.87 mA) helps maintain system efficiency and predictable standby behavior.
