LAQ2P391MELB30ZB

The LAQ2P391MELB30ZB is a Nichicon LAQ series aluminum electrolytic capacitor in a snap‑in terminal, radial can package. It provides 390 µF capacitance at a 220 V rated voltage with polarized design and is intended for general‑purpose applications.

This part is optimized for board‑level, high‑ripple environments with specified low‑frequency and high‑frequency ripple current ratings, a wide operating temperature range of −25°C to +105°C, and a 2000‑hour endurance at 105°C.

Key Features

• Capacitance & Voltage — 390 µF rated capacitance with a 220 V rated voltage and ±20% tolerance (at 120 Hz, 20°C).
• Snap‑in Radial Can Package — Snap‑in terminal mounting in a radial can (φ30 × 30 mm) for secure board installation and mass production handling (tray packing).
• High Ripple Current Capability — Rated ripple current of 1.35 A at 120 Hz (low frequency) and 1.62 A at 10 kHz (high frequency), specified for the part.
• Low Leakage — Specified leakage current of 0.87 mA after application of rated voltage.
• Wide Temperature & Endurance — Operating temperature range −25°C to +105°C with endurance of 2000 hours at 105°C under rated DC bias plus rated ripple current.
• Polarized Design — Polarized aluminum electrolytic capacitor for DC applications requiring electrolytic polarity.

Typical Applications

• General‑Purpose Board Designs — Use where a 390 µF, 220 V polarized snap‑in capacitor is required for general‑purpose applications.
• High‑Ripple Environments — Suitable where specified ripple handling is needed: 1.35 A at 120 Hz and 1.62 A at 10 kHz.
• High‑Temperature Endurance Requirements — For designs that require capacitor endurance at elevated temperatures (2000 hours at 105°C) within general‑purpose equipment.

Unique Advantages

• High ripple tolerance: Explicit ripple ratings at both 120 Hz and 10 kHz ensure the capacitor’s suitability where alternating current ripple is a design constraint.
• Compact snap‑in form factor: φ30 × 30 mm radial can with snap‑in terminals enables secure mechanical mounting and efficient board layout for production builds.
• Long high‑temperature life: 2000 hours endurance at 105°C under rated conditions supports reliability in thermally demanding assemblies.
• Controlled leakage current: Specified leakage of 0.87 mA gives predictable standby and operating leakage characteristics for power budget planning.
• Production‑friendly packaging: Tray packing and mass production readiness simplify procurement and assembly flow for volume builds.
