LAK2G121MELA30ZB

The LAK2G121MELA30ZB is a Nichicon LAK series snap-in aluminum electrolytic capacitor specified at 120 µF and 400 V. It is a snap‑in terminal, radial can type designed for general-purpose electronic equipment that requires high-voltage bulk capacitance and robust thermal endurance.

Key value propositions include rated operation to 105°C with 2000 hours endurance under rated ripple current, engineered safety features for abnormally excessive voltage, and measurable ripple performance at both low and high frequencies—making it suitable for applications operating in environments with voltage fluctuation.

Key Features

• Capacitance and Tolerance — 120 µF nominal with tolerance of -20% to +20% (measured at 120 Hz, 20°C).
• High Voltage Rating — Rated for 400 V DC to support higher-voltage circuits within the LAK series extended voltage range.
• Temperature and Endurance — Operating temperature range of -25°C to 105°C with endurance of 2000 hours at 105°C under rated ripple current.
• Ripple Current Performance — Low-frequency ripple current: 600 mA at 120 Hz; high-frequency ripple current: 690 mA at 10 kHz, enabling effective operation under AC ripple stress.
• Leakage and Loss Characteristics — Specified leakage current of 650 µA and tanδ (loss tangent) of 0.20 max at 120 Hz, 20°C for predictable loss and leakage behavior.
• Snap-in Mounting — Snap-in terminal radial can package for secure PCB mounting and suitability for tray packing in mass-production environments.
• Safety Features — LAK series includes improved safety features for abnormally excessive voltage and a pressure relief vent design to mitigate hazardous conditions.
• RoHS Compliant — Compliant with RoHS directive (2011/65/EU, (EU)2015/863).
• Compact Form Factor — Size φ25 × 30 mm (diameter × length) for placement in constrained enclosures.

Typical Applications

• Industrial equipment subject to voltage fluctuation — Suitable for systems where supply voltages vary, leveraging the LAK series’ safety design and extended voltage options.
• Power conversion and supply modules — Used where high-voltage bulk capacitance and rated ripple handling are required to support DC bus and smoothing functions.
• General-purpose high-voltage circuits — Applicable wherever a 400 V, 120 µF polarized electrolytic capacitor with robust thermal endurance is needed.

Unique Advantages

• High-temperature endurance: 2000 hours at 105°C under rated ripple current provides longer operational life in hot environments.
• Dual-frequency ripple capability: Rated ripple current values at 120 Hz and 10 kHz allow specification for both low- and high-frequency ripple conditions.
• Enhanced safety under abnormal voltage: LAK series safety features and pressure relief vent reduce risk in the event of excessive voltage stress.
• Predictable loss and leakage: Specified tanδ (0.20 max) and leakage current allow reliable thermal and power-loss budgeting in designs.
• Production-ready packaging: Tray packing and snap-in terminals support automated assembly and secure chassis mounting for volume production.
• Regulatory compliance: RoHS compliance supports use in regions requiring restricted substances conformity.
