LAKW6151MELC25ZB

The LAKW6151MELC25ZB is an aluminum electrolytic, snap-in terminal capacitor designed for high-voltage, general-purpose power applications. It delivers 150 µF capacitance at a 420 V rating with polarized construction and snap-in radial can packaging for secure board mounting.

Engineered for durability in demanding environments, this part withstands rated ripple current at 105°C for 2000 hours, supports an extended voltage range (200 V, 400 V and 420 V series), and incorporates improved safety measures for abnormally excessive voltage. It is RoHS compliant.

Key Features

• High voltage rating — Rated at 420 V to support high-voltage DC circuits and systems within the LAK series' extended voltage range (200 V, 400 V, 420 V).
• 150 µF capacitance with ±20% tolerance — Provides energy storage and smoothing with standard electrolytic tolerance for general-purpose designs.
• 105°C endurance — Specified operating temperature range of -25°C to +105°C with endurance tested to 2000 hours at 105°C under rated ripple conditions.
• Robust ripple handling — Rated ripple current of 820 mA at 120 Hz and 943 mA at 10 kHz, supporting AC ripple and high-frequency stress within its ratings.
• Safety features for abnormal voltage — Designed with improved safety measures and a pressure relief vent to mitigate hazards under abnormally excessive voltage conditions.
• Snap-in radial can package — Snap-in terminal, radial can construction for secure mounting and serviceable installation on power PCBs; size specified as L: 2.5 × D: 3.5 cm.
• RoHS compliant — Meets RoHS directive requirements (2011/65/EU, (EU)2015/863).

Typical Applications

• Equipment in voltage-fluctuating areas — Designed specifically to perform in systems where supply voltage varies, thanks to improved safety measures and extended voltage range.
• General-purpose power circuits — Suitable for board-level smoothing and energy storage in general-purpose power electronics requiring 420 Vrated capacitors.
• High-temperature installations — With a -25°C to +105°C operating range and 2000-hour ripple endurance at 105°C, appropriate for applications exposed to elevated ambient temperatures.

Unique Advantages

• Long high-temperature endurance — 2000 hours of rated ripple current application at 105°C reduces maintenance and replacement frequency in hot operating environments.
• Extended high-voltage flexibility — Part of a family supporting 200 V, 400 V and 420 V nominal ratings, enabling consistent voltage-tier selection across designs.
• Enhanced safety design — Pressure relief and safety features limit hazardous outcomes under abnormal over-voltage conditions, improving system-level reliability.
• High ripple capability at multiple frequencies — Specified ripple current values at 120 Hz and 10 kHz support both line-frequency and higher-frequency ripple stress scenarios.
• Serviceable snap-in form factor — Radial snap-in can simplifies PCB mounting and replacement compared with non-snap packages.
• Regulatory compliance — RoHS compliance supports global environmental requirements for manufactured equipment.
