LAK2G680MELA25

The LAK2G680MELA25 is a snap-in terminal aluminum electrolytic capacitor rated 400 V with 68 µF capacitance and a φ25 × 25 mm can. It is a polarized, radial snap-in package designed for general-purpose power applications that experience voltage fluctuation.

Built for robust thermal and ripple endurance, this capacitor withstands rated ripple current for 2000 hours at 105°C and supports an extended voltage range used across the LAK series. It is RoHS compliant for environmental regulation alignment.

Key Features

• Snap-in terminal package — Radial, can-style snap-in mounting for secure mechanical retention and straightforward PCB assembly in power modules and filter banks.
• Electrical ratings — 68 µF nominal capacitance at a rated voltage of 400 V with capacitance tolerance of ±20% (−20% to +20%).
• High-temperature endurance — Rated for operation from −25°C to +105°C and endurance tested to 2000 hours at 105°C under rated ripple conditions.
• Ripple current capability — Specified ripple current values of 450 mA at 120 Hz and 517.5 mA at 10 kHz to support AC ripple handling in power supplies.
• Loss and leakage characteristics — Tangent of loss angle (tan δ) up to 0.20 max at 120 Hz, 20°C; leakage current specified as I ≤ 3√(C·V) (µA) after 5 minutes at 20°C.
• Enhanced safety design — Pressure relief vent and other safety measures that operate to prevent dangerous conditions under abnormal overvoltage, per series safety performance specifications.
• Regulatory compliance — RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• Power supply filtering — Bulk and smoothing capacitor for high-voltage DC rails where 400 V rating and high ripple endurance are required.
• Industrial equipment — Useful in machinery and control systems operating in areas with voltage fluctuation thanks to its extended voltage range and safety features.
• Energy conversion and inverters — Supports AC ripple and DC-bias conditions in converter and inverter front-ends where thermal endurance to 105°C is needed.

Unique Advantages

• Long ripple-life at elevated temperature — 2000-hour endurance at 105°C under rated ripple current provides predictable life for demanding thermal environments.
• High-voltage capability — 400 V rating (part of an extended 200/400/420 V series) enables use on higher-voltage DC rails without series stacking.
• Clear electrical specifications — Published ripple current, leakage current formula, and tan δ make design validation and lifetime estimation straightforward.
• Safety-focused construction — Pressure relief vent and controlled safety test ratings reduce the risk of hazardous failure modes under abnormal voltage stress.
• Compact, serviceable package — φ25 × 25 mm can with snap-in terminals provides a compact footprint with secure board mounting for power assemblies.
