LAQ2G121MELA30ZB

The LAQ2G121MELA30ZB is a snap‑in terminal aluminum electrolytic capacitor from Nichicon’s LAQ series. It delivers 120 µF capacitance at a 400 V rating in a compact φ25 × 30 mm snap‑in can suited for general‑purpose power applications.

Designed for sustained high‑temperature operation, this part offers 2000 hours endurance at 105°C, elevated ripple current handling, and built‑in safety features for use in equipment exposed to voltage fluctuation. It is supplied in tray packing for mass production environments and is RoHS‑compliant.

Key Features

• Capacitance & Tolerance — 120 µF with ±20% tolerance (120 Hz, 20°C).
• High Voltage Rating — Rated for 400 V operation to support higher DC bus and power applications.
• Ripple Current Performance — 760 mA at 120 Hz and 874 mA at 10 kHz for robust ripple handling under varying frequency conditions.
• Endurance at Elevated Temperature — 2000 hours at 105°C when subjected to DC bias plus rated ripple current; capacitance, tan δ and leakage meet specified limits after the test.
• Leakage Current — Specified leakage current of 650 µA.
• Operating Temperature Range — −25°C to +105°C for broad environmental coverage.
• Package & Mounting — Snap‑in radial can (φ25 × 30 mm) for secure PCB mounting in high‑current assemblies; supplied in tray packing for production use.
• Safety Features — Improved safety design with a pressure relief vent to operate under abnormal voltage conditions without dangerous failure modes.
• Regulatory — Compliant to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General‑purpose power systems — Suitable where a 400 V, 120 µF capacitor is required for energy storage and DC link applications.
• Equipment in voltage‑fluctuating environments — LAQ series improvements and safety features make this part suitable for systems exposed to variable or abnormal voltages.
• Power supplies and converters — Designed for sustained ripple current operation, supporting smoothing and filtering in power conversion stages.

Unique Advantages
