LAK2G101MELB25

The LAK2G101MELB25 is a snap‑in terminal aluminum electrolytic capacitor from Nichicon’s LAK series, rated 100 µF at 400 V. It is designed for general‑purpose power applications where high voltage capability and robust thermal endurance are required.

This part supports operation across a broad temperature range (‑25°C to 105°C) and is engineered to withstand 2000 hours of rated ripple current at 105°C, making it suitable for equipment exposed to fluctuating voltages or demanding thermal conditions. The product is RoHS compliant.

Key Features

• Capacitance & Voltage: 100 µF nominal capacitance with a 400 V rated voltage for high‑voltage filtering and energy smoothing tasks.
• High Temperature Endurance: Rated for operation to 105°C with documented endurance of 2000 hours when subjected to rated ripple current at 105°C.
• Snap‑in Mounting: Radial, can snap‑in package for secure PCB retention in vertical assemblies and ease of assembly.
• Ripple Current Performance: Specified ripple current of 530 mA at 120 Hz and 609.5 mA at 10 kHz, supporting AC ripple handling across typical power system frequencies.
• Tolerance & Polarization: ±20% capacitance tolerance at 120 Hz, and polarized construction typical of aluminum electrolytic capacitors.
• Safety & Abnormal Voltage Handling: Improved safety features for abnormally excessive voltage and a pressure relief vent design to mitigate unsafe failure modes.
• Leakage & Loss Characteristics: Leakage current governed by I ≤ 3√CV (μA) after 5 minutes at 20°C; tan δ specified at 0.20 max (120 Hz, 20°C).
• RoHS Compliant: Conforms to applicable RoHS directives.

Typical Applications

• General‑Purpose Power Systems: High‑voltage filtering and bulk energy storage in equipment that requires 400 V capacitance.
• Equipment in Fluctuating‑Voltage Areas: Components exposed to variable input voltages where enhanced abnormal‑voltage safety features are advantageous.
• Industrial Power Assemblies: Applications requiring stable performance up to 105°C and documented endurance under rated ripple conditions.

Unique Advantages

• 400 V Rating for High‑Voltage Designs: Enables use in applications that require elevated DC voltage handling without series configurations.
• Thermal Endurance: 2000 hours at 105°C under rated ripple current supports long‑term reliability in hot operating environments.
• Secure Snap‑in Packaging: Radial snap‑in can simplifies mechanical retention on PCBs and supports vertical assembly profiles.
• Measured Ripple Performance: Published ripple current values at 120 Hz and 10 kHz aid thermal and lifetime calculations during design.
• Built‑in Safety Measures: Pressure relief vent and enhanced abnormal‑voltage handling reduce the risk of hazardous failures under overvoltage conditions.
• Regulatory Compliance: RoHS compliance reduces materials management overhead for regulated product lines.
