LAQ2P471MELB30ZB

The LAQ2P471MELB30ZB from Nichicon is a snap‑in terminal aluminum electrolytic capacitor from the LAQ series. It delivers 470 µF capacitance at a 220 V rating in a compact radial can (φ30 × 30 mm) designed for general‑purpose applications that require high ripple handling and elevated temperature endurance.

Key value propositions include a wide operating range (-25 °C to +105 °C), rated endurance of 2000 hours at 105 °C, and measured ripple current performance for both low and high frequency environments.

Key Features

• Capacitance & Voltage — 470 µF nominal capacitance with ±20% tolerance and a 220 V rated voltage suitable for higher‑voltage DC circuits.
• Thermal and Endurance Rating — Designed for operation from -25 °C to +105 °C with an endurance rating of 2000 hours at 105 °C under DC bias plus rated ripple current.
• 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 filtering under varying ripple conditions.
• Low Leakage — Specified leakage current of 0.91 mA, supporting stable DC performance after voltage application.
• Package & Mounting — Snap‑in radial can package (φ30 × 30 mm) for board‑level insertion and secure mechanical mounting in high‑density assemblies.
• Safety Feature — Pressure relief vent design to prevent dangerous conditions under abnormal voltage as described in the series safety performance notes.

Typical Applications

• Power supply filtering — Filtering and smoothing in DC power rails where 220 V rating and high ripple current capacity are required.
• Industrial electronics — General‑purpose energy storage and decoupling in equipment operating within -25 °C to +105 °C and requiring 2000 h endurance at elevated temperature.
• High‑voltage DC circuits — Bulk capacitance and ripple management in circuits that require a 220 V rated electrolytic capacitor.

Unique Advantages

• High voltage capability — 220 V rated voltage supports higher DC applications without additional component complexity.
• Long-term high‑temperature reliability — 2000 hours endurance at 105 °C ensures sustained performance in elevated temperature environments.
• Dual-frequency ripple handling — Specified ripple currents at both 120 Hz and 10 kHz provide predictable behavior across low and high ripple frequency conditions.
• Compact snap‑in form factor — φ30 × 30 mm radial can with snap‑in terminals simplifies mechanical mounting while conserving board area.
• Controlled leakage — Low measured leakage current (0.91 mA) for stable DC characteristics after voltage application.
• Series safety design — Pressure relief vent operation is specified to avoid flames or dispersion under abnormal conditions per the LAQ series safety notes.
