LAQ2G151MELZ40ZB

The LAQ2G151MELZ40ZB is an aluminum electrolytic capacitor from Nichicon's LAQ series, featuring a snap-in terminal radial can design. It delivers 150 µF capacitance at a 400 V rating in a compact φ22 × 40 mm package and is offered in tray packing for mass production.

Engineered for general-purpose high-voltage applications, this part combines a high operating temperature range and defined ripple-handling capability to support designs that require stable bulk energy storage and decoupling at elevated temperatures.

Key Features

• Capacitance & Voltage — 150 µF nominal capacitance with a 400 V rated voltage and ±20% tolerance, providing predictable high-voltage energy storage.
• Ripple Current Performance — Specified ripple handling of 850 mA at 120 Hz and 977.5 mA at 10 kHz to support AC ripple and switching load conditions within rated limits.
• Thermal and Endurance — Rated for operation from −25°C to 105°C with a 2000 hour endurance at 105°C under rated conditions, supporting sustained higher-temperature operation.
• Leakage and Loss — Low leakage current specified at 730 µA and a loss tangent (tan δ) spec consistent with LAQ series limits for predictable performance after voltage application.
• Package & Mounting — Snap-in terminal, radial can (φ22 × 40 mm) for secure board mounting; tray packing suited to production assembly.
• Safety Design — Includes a pressure relief vent feature as specified in the LAQ series safety performance for controlled venting under abnormal conditions.

Typical Applications

• High-voltage general-purpose circuits — Provides 150 µF at 400 V for general-purpose high-voltage capacitor needs where compact, snap-in mounting is required.
• Power electronics and supplies — Ripple current ratings and 105°C endurance make the part suitable for smoothing and energy storage in higher-temperature power modules and supplies.
• Industrial equipment — Robust operating temperature range and long endurance at 105°C support use in industrial assemblies requiring reliable bulk capacitance.

Unique Advantages

• High-voltage capability: 400 V rating enables use in higher-voltage DC circuits without series stacking.
• Compact snap-in form factor: φ22 × 40 mm radial can with snap-in terminals simplifies secure PCB mounting in production environments.
• Defined ripple performance: Dual-frequency ripple current specs (120 Hz and 10 kHz) give designers clear guidance for AC and switching environments.
• Extended high-temperature life: 2000 hours at 105°C provides predictable long-term behavior in elevated-temperature applications.
• Low leakage: 730 µA leakage current helps maintain efficiency and reduces standby losses in DC circuits.
• Production-ready packaging: Tray packing and mass production status support procurement and assembly scale-up.
