LAQ2D471MELZ40ZB

The LAQ2D471MELZ40ZB from Nichicon is a snap‑in terminal aluminum electrolytic capacitor in the LAQ series, rated at 470 µF and 200 V. It is designed for general‑purpose electronic equipment requiring high capacitance, elevated voltage handling and board‑mounted snap‑in installation.

Key electrical characteristics include a ±20% capacitance tolerance, low leakage current, specified ripple current values at low and high frequency, and a 2000‑hour endurance rating at 105°C—offering a balance of performance and long‑term reliability in compact φ22 × 40 mm packaging.

Key Features

• Capacitance & Voltage — 470 µF nominal capacitance with a 200 V rated voltage and ±20% tolerance, suitable for applications that need substantial bulk capacitance at elevated voltage.
• Ripple Current Performance — Rated ripple current of 1.45 A at 120 Hz (low frequency) and 1.74 A at 10 kHz (high frequency), enabling effective AC ripple handling in filtering and decoupling roles.
• Low Leakage — Specified leakage current of 0.91 mA, supporting stable performance over time after voltage application.
• Endurance at Elevated Temperature — 2000 hours life at 105°C under DC bias plus rated ripple current, with defined limits for capacitance change, tan δ and leakage current after test.
• Operating Temperature Range — Rated for −25°C to +105°C operation, covering typical industrial and general‑purpose ambient conditions.
• Snap‑In Mounting & Package — Radial, can‑style snap‑in terminals for secure board mounting; compact dimensional footprint of φ22 × 40 mm (L: 4.0 cm × D: 2.2 cm).
• Safety Performance — Designed with a pressure relief vent that operates without producing flames, ignition, or dispersion of parts under the specified test conditions.

Typical Applications

• General‑purpose power systems — Bulk capacitance and ripple handling for power supply filtering in general electronic equipment where a 200 V, 470 µF capacitor is required.
• High‑voltage DC decoupling — Provides bulk energy storage and smoothing in circuits operating up to 200 V, benefiting from the specified ripple current ratings and low leakage.
• Industrial and commercial electronics — Use in board‑mounted designs that demand elevated temperature endurance (2000 h at 105°C) and reliable snap‑in mechanical retention.

Unique Advantages

• High working voltage with high capacitance: 200 V rating combined with 470 µF gives substantial energy storage for designs constrained by voltage and space.
• Dual‑frequency ripple specification: Published ripple currents at 120 Hz and 10 kHz allow designers to evaluate performance across both low and high frequency ripple environments.
• Long endurance at elevated temperature: 2000 hours at 105°C under DC bias plus rated ripple current supports extended in‑service life in warm operating conditions.
• Compact, board‑friendly snap‑in package: φ22 × 40 mm radial can with snap‑in terminals simplifies PCB mounting while preserving a small footprint.
• Controlled leakage and stability: Low leakage current (0.91 mA) and specified limits for capacitance and tan δ after endurance and shelf‑life tests help maintain predictable circuit behavior.
• Built‑in safety considerations: Pressure relief vent design mitigates hazardous outcomes under abnormal conditions per the LAQ series safety performance description.
