LAK2G151MELC25

The LAK2G151MELC25 is a snap-in terminal aluminum electrolytic capacitor designed for general-purpose power applications. It delivers 150 µF capacitance at a 400 V rating with snap-in mounting in a radial can package, and is intended for equipment operating in environments with fluctuating voltages.

Engineered for endurance at elevated temperature, this part withstands rated ripple current for 2000 hours at 105°C, offers improved safety features against abnormal over-voltage, and is RoHS compliant.

Key Features

• Rated Capacitance and Voltage — 150 µF nominal capacitance with a 400 V rated DC voltage suitable for high-voltage power rails.
• Snap-In Radial Can Package — Snap-in terminal type in a radial can package for secure mechanical mounting and easy installation into power assemblies.
• High-Temperature Endurance — Qualified for 2000 hours of rated ripple current application at 105°C, supporting sustained operation in hot operating environments.
• Permissible Abnormal Voltage / Safety — Designed with improved safety features and a pressure relief vent that operates without dangerous conditions under abnormal excessive voltage.
• Ripple Current Capability — Rated ripple currents of 700 mA at 120 Hz and 805 mA at 10 kHz to support smoothing and filtering in noisy power systems.
• Operating Range and Tolerance — Operating temperature range −25°C to +105°C and capacitance tolerance of ±20% (at 120 Hz, 20°C).
• Leakage and Loss Characteristics — Leakage current defined by I ≤ 3√(C·V) µA after 5 minutes at 20°C; tan δ ≤ 0.20 (120 Hz at 20°C).
• Compact Size — Dimensions approximately L: 2.5 × D: 3.5 cm for space-conscious power designs.
• RoHS Compliant — Meets RoHS directive requirements (2011/65/EU, (EU)2015/863).

Typical Applications

• Power supply smoothing — Provides bulk capacitance and ripple handling for DC power rails in equipment exposed to fluctuating input voltages.
• Industrial power equipment — Suited for general-purpose industrial systems where high-temperature endurance and over-voltage safety are required.
• High-ripple circuits — Applicable where sustained ripple current capability at elevated temperature is needed for filtering and decoupling.

Unique Advantages

• Long-duration high-temperature reliability: 2000-hour rated ripple endurance at 105°C supports sustained operation in hotter environments, reducing replacement frequency.
• Enhanced safety under abnormal voltage: Improved safety features and a pressure relief vent mitigate hazardous failure modes when exposed to excessive voltages.
• High-voltage capability: 400 V rating (part of an extended range including 200 V and 420 V in the series) enables use on higher-voltage power rails without series stacking.
• Robust ripple performance: Defined ripple current ratings at both 120 Hz and 10 kHz support performance across common power-conversion frequencies.
• Board-ready snap-in mounting: Snap-in radial can package simplifies mechanical retention and assembly in power modules and chassis-mounted designs.
• Regulatory compliance: RoHS conformity supports use in designs targeting current environmental directives.
