LAQ2D471MELA30

The LAQ2D471MELA30 is a Nichicon LAQ series aluminum electrolytic capacitor in a snap-in terminal (radial can) package. It provides 470 µF capacitance at a 200 V rating and is designed for general-purpose power applications that require high-voltage handling, elevated ripple capability, and extended endurance.

Engineered for production use, this part is offered in tray packing and supports continuous operation across an operating temperature range of -25°C to 105°C with a rated endurance of 2000 hours at 105°C.

Key Features

• Capacitance & Voltage — 470 µF nominal capacitance with ±20% tolerance and a rated voltage of 200 V, suitable for higher-voltage DC rails.
• High Ripple Current — 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 filtering under varying load conditions.
• Loss and Leakage — Specified tangent of loss angle (tan δ) of 0.20 max at 20°C, 120 Hz, and a measured leakage current of 910 µA for predictable performance.
• Endurance & Temperature Range — Life rating of 2000 hours at 105°C and an operating temperature range from -25°C to 105°C for long-term stability in elevated-temperature environments.
• Snap-in Radial Can Package — Snap-in terminal mounting (radial, can-type) in a compact φ25 × 30 mm package for secure board attachment and high-density assemblies.
• Safety & Robustness — Series-level features include improved safety for abnormally excessive voltage and a pressure-relief vent designed to operate without flame or dangerous dispersion under fault conditions.
• Regulatory — LAQ series capacitors are compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Power Supplies — Bulk smoothing and ripple filtering on 200 V DC rails where high ripple current and elevated voltage capability are required.
• Inverters and UPS — Energy storage and filtering for intermediate DC links, leveraging the part’s 200 V rating and long endurance at 105°C.
• Power Conversion Modules — Support for DC–DC converters and line-powered converters that demand durable capacitors with predictable leakage and loss characteristics.
• Motor Drives — DC bus smoothing and transient absorption in motor control and drive assemblies that benefit from snap-in mounting and robust ripple handling.

Unique Advantages

• High-voltage capability: 200 V rated voltage enables use on elevated DC rails where lower-voltage capacitors would be unsuitable.
• Superior ripple handling: 1.45 A (120 Hz) and 1.74 A (10 kHz) ripple ratings reduce heating and extend service life under AC ripple conditions.
• Long elevated-temperature life: 2000 hours at 105°C provides design confidence for applications operating in warm environments.
• Predictable electrical loss and leakage: tan δ ≤ 0.20 and specified leakage current support stable filter and timing behavior in power electronics.
• Robust snap-in packaging: Radial snap-in can (φ25 × 30 mm) simplifies board mounting for high-current power assemblies.
• Safety-minded design: Pressure-relief venting and series safety features help mitigate abnormal-voltage stress scenarios.
