LAK2G680MELA25ZB

The LAK2G680MELA25ZB from Nichicon is a snap‑in terminal aluminum electrolytic capacitor designed for general‑purpose power applications. It features a 68 µF capacitance at a 400 V rating in a compact radial can (φ25 × 25 mm) and is polarized for DC applications.

Engineered for environments with fluctuating supply voltages, this part delivers extended voltage range options, built‑in safety performance for abnormal overvoltage conditions, and endurance for elevated operating temperatures.

Key Features

• Snap‑in terminal package — Radial, can‑style snap‑in mounting (φ25 × 25 mm) for secure board retention and ease of installation.
• 400 V rated voltage, 68 µF capacitance — Provides energy storage and smoothing at high DC voltages for demanding power circuits.
• High temperature endurance — Withstands 2000 hours of rated ripple current at 105 °C, supporting reliable operation in elevated ambient conditions.
• Ripple current capability — Rated ripple current: 450 mA at 120 Hz and 517.5 mA at 10 kHz, enabling effective AC ripple handling in DC power rails.
• Safety performance for abnormal voltage — Improved safety features and a pressure relief vent designed to operate without flames or dangerous dispersion under test conditions.
• Wide operating temperature range — Specified for −25 °C to +105 °C to cover a broad set of operating environments.
• Leakage current specification — Leakage current follows I ≤ 3√(C·V) µA after 5 minutes at 20 °C, providing a measurable baseline for design verification.
• RoHS compliant — Conforms to the RoHS directive (2011/65/EU, (EU)2015/863).
• Capacitance tolerance — ±20% at 120 Hz, 20 °C for predictable design margins.

Typical Applications

• Power supply smoothing — Energy storage and ripple attenuation on DC rails where supply voltages may fluctuate.
• Industrial equipment — General‑purpose use in machinery and control equipment operating in environments with variable line voltages.
• Commercial electronic equipment — Bulk capacitance and filtering for commercial power electronics that require high voltage capability.

Unique Advantages

• Robust high‑temperature endurance: 2000 hours at 105 °C under rated ripple current supports long service life in hot operating conditions.
• Extended voltage options: Part of a series that includes 200 V, 400 V and 420 V ratings, providing flexibility for different system voltages.
• Designed for voltage fluctuation environments: Improved safety features and pressure relief venting reduce risk during abnormal overvoltage events.
• Measured ripple handling: Specified ripple current values at 120 Hz and 10 kHz help quantify thermal and lifetime margins during design.
• Compact, serviceable form factor: φ25 × 25 mm snap‑in can simplifies layout in power assemblies while ensuring secure board attachment.
• Regulatory compliance: RoHS conformity supports environmental and supply‑chain requirements.
