LAKW6181MELC30

The LAKW6181MELC30 is a snap-in, radial can aluminum electrolytic capacitor designed for general-purpose power applications. It combines a high rated voltage (420 V) with 180 µF capacitance and a snap-in mounting style for secure chassis/board installation.

Engineered for operation from -25°C to 105°C and specified for 2000 hours of rated ripple-current endurance at 105°C, this part is targeted at equipment used in voltage-fluctuating environments where extended thermal and electrical durability and enhanced safety features are required. The part is RoHS compliant.

Key Features

• Electrical Rating — 180 µF capacitance with a rated voltage of 420 V and capacitance tolerance of ±20% (120 Hz, 20°C).
• High Ripple Capability — Rated ripple current: 900 mA at 120 Hz and 1.035 A at 10 kHz, suitable for continuous ripple-current applications within specified limits.
• High-Temperature Endurance — Specified to withstand 2000 hours of rated ripple current at 105°C with defined endurance criteria for capacitance, tan δ and leakage current.
• Safety Performance — Improved safety features including a pressure-relief vent designed to operate without flames, ignition, or scattering of parts under abnormal excessive voltage conditions.
• Leakage and Dissipation — Leakage current defined by I ≤ 3√(C·V) µA after 5 minutes at 20°C; tangent of loss angle (tan δ) 0.20 max at 120 Hz, 20°C.
• Package & Mounting — Radial can, snap-in terminal type with physical size approximately L: 3 cm × D: 3.5 cm and seated height up to 1.181 inch for secure mechanical installation.
• Environmental Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Power conversion and filtering — Bulk smoothing and energy storage in general-purpose power supplies where high voltage rating and ripple handling are required.
• Equipment in fluctuating-voltage environments — Designed for use in systems exposed to variable input voltages, leveraging endurance at 105°C and safety venting for abnormal overvoltage events.
• Industrial electronics — General-purpose use in industrial control and power electronics that require robust capacitors rated for elevated temperature and continuous ripple current.

Unique Advantages

• 420 V rating with substantial capacitance — Enables high-voltage DC link and smoothing applications without combining multiple lower-voltage units.
• Validated high-temperature endurance — 2000 hours at 105°C under rated ripple current demonstrates stability for long-term operation in hot environments.
• Defined leakage and dissipation characteristics — Leakage current formula and tan δ limit provide clear, verifiable performance expectations for designers.
• Built-in safety measures — Pressure-relief vent and improved safety design reduce risk under abnormal excessive voltage conditions.
• Snap-in mounting — Radial, snap-in package offers a mechanically secure installation option suited to high-vibration or chassis-mounted assemblies.
• RoHS compliant — Meets current restricted-substance requirements for regulated markets.
