LAK2G101MELA30ZB

The LAK2G101MELA30ZB is a Nichicon LAK series aluminum electrolytic capacitor in a snap‑in, radial can package. It provides 100 µF capacitance at a 400 V rating with ±20% tolerance and is designed for general‑purpose power applications.

Engineered for sustained operation in demanding environments, this snap‑in capacitor offers 2000 hours of endurance at 105°C, defined ripple current ratings at both low and high frequencies, and safety features for use in equipment exposed to fluctuating voltages.

Key Features

• Electrical Performance — 100 µF capacitance at 400 V nominal with ±20% tolerance and a maximum tanδ of 0.20 (measured at 20°C, 120 Hz) for predictable AC loss characteristics.
• High‑temperature Endurance — Rated to withstand 2000 hours of D.C. bias plus rated ripple current at 105°C, with specified limits on capacitance change, tanδ, and leakage after the endurance test.
• Ripple Current Capability — Low‑frequency ripple current 530 mA (120 Hz) and high‑frequency ripple current 609.5 mA (10 kHz) to support smoothing and filtering in power circuits.
• Leakage Current — Specified leakage current of 600 µA (after rated voltage application) to help quantify standby loss and discharge behavior.
• Package & Mounting — Snap‑in radial can (φ25 × 30 mm) designed for PCB snap‑in installation; supplied in tray packing for production assembly.
• Safety & Voltage Robustness — Part of the LAK series that includes improved safety features for abnormally excessive voltage and a pressure relief vent designed to operate without hazardous conditions.
• Compliance — RoHS‑compliant material composition.

Typical Applications

• General purpose power filtering — Bulk smoothing and decoupling in power supplies and converters where a 400 V rating and 100 µF capacitance are required.
• Equipment exposed to voltage fluctuations — Suited for systems operating in environments with variable supply voltages thanks to the LAK series’ enhanced voltage tolerance and safety design.
• High‑temperature systems — Applications that demand extended operation at elevated temperatures, leveraging the 2000 h endurance at 105°C.

Unique Advantages

• High‑voltage capability: 400 V rating provides headroom for high‑voltage DC link and filtering applications without compromising capacitance.
• Defined long‑term reliability: 2000 hours endurance at 105°C with measurable limits on capacitance, tanδ and leakage supports predictable lifetime performance.
• Measured ripple performance: Specified ripple currents at 120 Hz and 10 kHz let designers size thermal and ripple handling precisely for both low and high frequency stress.
• Safety‑oriented design: Series‑level pressure relief and improved abnormal‑voltage behavior reduce the likelihood of hazardous failures under extreme conditions.
• Production‑ready packaging: Tray packing and snap‑in mounting simplify handling and installation for mass production environments.
• Regulatory compliance: RoHS compliance supports deployment in regions requiring restricted‑substance conformance.
