LAQ2D471MELB25ZB

The LAQ2D471MELB25ZB is a snap-in terminal aluminum electrolytic capacitor offering 470 µF capacitance at a 200 V rating in a compact radial can. It is part of Nichicon's LAQ series, designed for general-purpose power applications that require high ripple handling and robust high-temperature endurance.

With a 25 mm diameter and 25 mm length (L: 2.5 × D: 3 cm), snap-in mounting and a 2000-hour rated life at 105°C, this component targets power-electronics and industrial equipment where compact bulk capacitance, reliable operation under fluctuating voltages, and predictable performance are needed.

Key Features

• Electrical Capacity and Rating — 470 µF nominal capacitance with ±20% tolerance at 120 Hz, rated for 200 V DC operation.
• High Ripple Current Capability — Rated ripple current of 1.45 A at 120 Hz (low frequency) and 1.74 A at 10 kHz (high frequency) to support smoothing and decoupling in power circuits.
• Low Leakage — Initial leakage current specified at 0.91 mA, supporting predictable standby and no-load behavior after voltage application.
• High-Temperature Endurance — Designed for 2000 hours life at 105°C under rated conditions, with post-test limits for capacitance, tan δ and leakage current defined by the series specification.
• Compact Snap-in Package — Radial, can-type snap-in terminals for robust board mounting and efficient assembly; tray packing suitable for mass production.
• Safety and Compliance — Pressure-relief venting designed to operate without flame or dispersion under abnormal conditions; LAQ series is compliant with the RoHS directive (2011/65/EU, (EU)2015/863) per series documentation.

Typical Applications

• Industrial Power Electronics — Bulk smoothing and energy storage in general-purpose industrial power supplies and control equipment operating at elevated temperatures.
• Equipment Subject to Voltage Fluctuations — Designs that require stable capacitance and safety features where supply voltages can vary or experience transients.
• Switching Power Supplies and Converters — Input/output filtering and ripple current management where higher-frequency ripple handling is required.

Unique Advantages

• 200 V Rating for Higher-Voltage Designs — Enables use in circuits requiring elevated DC working voltages without adding multiple components in series.
• Measured High-Frequency Performance — Specified ripple current at 10 kHz (1.74 A) provides quantifiable behavior for converter and switching applications.
• Proven High-Temperature Life — 2000-hour endurance at 105°C gives designers a clear baseline for thermal longevity and lifecycle planning.
• Compact Form Factor with Snap-in Mounting — 25 mm × 25 mm size and snap-in terminals reduce board footprint while providing secure mechanical attachment for high-reliability assemblies.
• Series-Level Safety Features — Pressure-relief vent operation and RoHS compliance provide both operational safety and regulatory alignment where applicable.
