LAQ2P391MELA35ZB

The LAQ2P391MELA35ZB is a snap‑in terminal aluminum electrolytic capacitor from Nichicon’s LAQ series. It provides 390 µF capacitance at a 220 V rating in a compact φ25 × 35 mm can with snap‑in mounting, targeted for general‑purpose electronic equipment.

Designed for applications that require high working voltage, defined ripple handling and elevated temperature endurance, this part delivers measurable performance metrics including ripple current ratings, leakage current, and a 2000‑hour endurance at 105°C.

Key Features

• Capacitance and Tolerance — 390 µF with ±20% tolerance (measured at 120 Hz, 20°C), suitable where specified bulk capacitance is required.
• Rated Voltage — 220 V DC rating for higher‑voltage circuits.
• Snap‑in Radial Package — φ25 × 35 mm (L: 3.5 × D: 2.5 cm) radial can with snap‑in terminals for secure chassis or PCB mounting and simplified assembly; supplied in tray packing and available in mass production.
• Ripple Current Specification — 1350 mA at low frequency (120 Hz) and 1620 mA at high frequency (10 kHz), enabling defined AC ripple handling for DC bus filtering and smoothing duties.
• Loss Tangent (tan δ) — 0.20 max at 20°C, 120 Hz, providing a specified dissipation factor for thermal and impedance planning.
• Leakage Current — 870 µA specified after rated voltage application, allowing predictable standby and leakage behavior.
• Temperature and Endurance — Operating range −25°C to +105°C with 2000 hours endurance at 105°C under rated conditions, per LAQ series endurance criteria.

Typical Applications

• General Purpose Electronics — Suitable for general‑purpose smoothing and energy storage in electronic equipment requiring a 220 V, 390 µF snap‑in capacitor.
• Power Supply Filtering — Used where defined ripple current ratings (1.35 A @120 Hz, 1.62 A @10 kHz) and 220 V capability are required for bulk decoupling and filtering.
• Industrial Equipment — Appropriate for industrial designs operating within −25°C to +105°C that need a high‑voltage electrolytic capacitor with specified endurance.

Unique Advantages

• High working voltage: 220 V rating supports higher‑voltage circuits without up‑rating multiple lower‑voltage parts.
• Defined ripple handling: Explicit low‑ and high‑frequency ripple current ratings (1350 mA / 1620 mA) allow precise thermal and reliability calculations.
• Compact snap‑in form factor: φ25 × 35 mm radial can with snap‑in terminals simplifies mechanical retention and assembly for through‑hole layouts.
• Known loss and leakage behavior: Specified tan δ (0.20 max at 20°C, 120 Hz) and leakage current (870 µA) enable predictable performance modeling.
• Extended endurance at elevated temperature: 2000 hours at 105°C under rated conditions provides a measurable reliability baseline for thermal stress planning.
• Mass production availability: Tray packing and mass production status support volume procurement and consistent supply for production programs.
