LAQ2G151MELA35ZB

The LAQ2G151MELA35ZB is a snap‑in terminal aluminum electrolytic capacitor from Nichicon’s LAQ series. It is a polarized, radial can package designed for general‑purpose power applications that require a 400 V rated voltage and 150 µF capacitance.

Engineered for high‑temperature endurance and voltage‑fluctuating environments, this part withstands 2000 hours of D.C. bias plus rated ripple current at 105°C and incorporates enhanced safety features for abnormal overvoltage conditions. It is RoHS compliant.

Key Features

• Capacitance & Voltage: 150 µF nominal capacitance with a 400 V rated voltage and ±20% tolerance.
• High‑temperature Endurance: Rated for 2000 hours of operation at 105°C under D.C. bias plus rated ripple current per series endurance specification.
• Ripple Current Capability: 850 mA at 120 Hz and 977.5 mA at 10 kHz, supporting effective ripple suppression in power circuits.
• Package & Mounting: Snap‑in radial can (snap‑in terminal type) for secure, PCB‑mounted power applications; nominal dimensions L: 3.5 × D: 2.5 cm.
• Temperature Range: Operating range from −25°C to +105°C.
• Leakage & Loss Characteristics: Leakage current meets I ≤ 3√C µA after 5 minutes at 20°C; tan δ ≤ 0.20 at 120 Hz, 20°C.
• Safety Features: Pressure relief vent and design provisions to mitigate dangerous conditions under abnormal excessive voltage.
• RoHS Compliance: Conforms to RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Power Supplies: Smoothing and filtering in high‑voltage power supplies where 400 V rated capacitors and elevated ripple handling are required.
• Equipment in Voltage‑Fluctuating Areas: Suitable for electronic equipment exposed to unstable line voltages due to its allowable abnormal voltage characteristics and safety vent.
• General‑Purpose Power Electronics: Bulk decoupling and energy storage in general commercial and industrial electronic systems requiring robust 105°C performance.

Unique Advantages

• Long Endurance at High Temperature: 2000‑hour rated life at 105°C under rated ripple current provides predictable ageing for demanding thermal environments.
• High Voltage Support: 400 V rating enables use in higher‑voltage power rails without series stacking.
• Strong Ripple Performance: Specified ripple current values at both low and high frequencies reduce heating and extend service life in AC‑ripple heavy applications.
• Compact Snap‑In Form Factor: Smaller case sizes (compared to earlier LAK series) allow tighter power supply layouts while maintaining high performance.
• Built‑in Safety Measures: Pressure relief vent and permissible abnormal voltage design reduce risk of hazardous failure modes under overvoltage conditions.
• Regulatory Compliance: RoHS compliance supports deployment in regions requiring restricted substances conformity.
