LAK2G101MELB25ZB

The LAK2G101MELB25ZB from Nichicon is a snap‑in terminal aluminum electrolytic capacitor in the LAK series, rated for 400 V and 100 µF. It is designed for general‑purpose power applications where extended voltage range, high ripple endurance and enhanced safety under abnormal voltage conditions are required.

Key value comes from its 105 °C permissible abnormal voltage design, the ability to withstand rated ripple current for 2000 hours at 105 °C, and series-level safety measures intended for equipment operating in fluctuating-voltage environments.

Key Features

• Electrical: 100 µF, 400 V — Rated capacitance 100 µF with a 400 V rated voltage for higher-voltage power circuits.
• High‑temperature endurance — Specified to withstand 2000 hours of rated ripple current at 105 °C, supporting long-term operation in elevated-temperature applications.
• Ripple current performance — Rated ripple current: 530 mA at 120 Hz and 609.5 mA at 10 kHz, suitable for applications with continuous AC ripple loads.
• Safety performance — Improved safety features for abnormal excessive voltage; pressure relief vent operation is specified to avoid dangerous conditions in normal test scenarios.
• Limited DC current rating (series test) — For the 400 V range and capacitance group 100 ≤ C < 220 µF the series limited DC current rating is specified as 4 A under test conditions included in the datasheet.
• Polarized, snap‑in radial can package — Snap‑in terminal mounting for secure chassis or board attachment in radial, can‑style packaging.
• Operating range & tolerance — Operating temperature −25 °C to +105 °C and capacitance tolerance ±20% (measured at 120 Hz, 20 °C).
• RoHS compliant — Meets RoHS directive (2011/65/EU,(EU)2015/863).
• Leakage current specification — Series leakage current defined as I ≤ 3√(C·V) µA after 5 minutes at 20 °C (C: µF, V: V), enabling predictable leakage behavior for design calculations.
• Compact footprint — Size: L: 2.5 × D: 3 cm, providing a space-conserving solution for power assemblies.

Typical Applications

• Equipment in fluctuating‑voltage environments — Suited for systems exposed to supply variations where enhanced abnormal‑voltage handling and safety are important.
• General‑purpose power circuits — Bulk filtering and energy storage in power conversion stages requiring 400 V components and elevated temperature endurance.
• High‑ripple circuits — Where sustained ripple current at elevated temperature is a design requirement, the LAK2G101MELB25ZB provides specified ripple ratings at both low and high frequencies.

Unique Advantages

• Designed for high-temperature endurance: 2000 hours rated ripple endurance at 105 °C reduces risk of premature degradation in hot operating environments.
• Extended high‑voltage capability: 400 V rating supports higher-voltage power designs without up‑rating multiple lower‑voltage parts.
• Measured ripple performance: Published ripple current values at 120 Hz and 10 kHz allow engineers to size capacitors against real operating ripple conditions.
• Series safety test coverage: Specified limited DC current and pressure relief behavior under abnormal voltage test conditions improve predictable failure modes and safety handling.
• Compact snap‑in package: Radial snap‑in can simplifies mechanical mounting for chassis or board assemblies while maintaining secure electrical connection.
• Regulatory conformity: RoHS compliance supports environmentally regulated product designs.
