LAKW6181MELC30ZB

The LAKW6181MELC30ZB is a snap-in terminal aluminum electrolytic capacitor from Nichicon's LAK series, rated 180 µF at 420 V. It is designed for general-purpose power applications that require high-voltage bulk capacitance with snap-in mounting for secure chassis or PCB installation.

Key value comes from its high-voltage capability, extended thermal endurance (2000 hours at 105°C), and built-in safety features for abnormal over-voltage conditions—making it suitable for equipment operating in voltage-fluctuating environments. This part is offered in tray packing for mass production use.

Key Features

• Capacitance & Voltage — 180 µF nominal capacitance with a 420 V rated voltage for high-voltage DC link and smoothing applications.
• Thermal Endurance — Rated for 2000 hours at 105°C under specified ripple/current conditions, supporting demanding thermal environments.
• High Ripple Capability — Ripple current ratings of 900 mA at 120 Hz and 1.035 A at 10 kHz enable effective AC ripple handling in power circuits.
• Safety & Abnormal Voltage Resistance — LAK series improvements include enhanced safety features and a pressure relief vent designed to operate without dangerous outcomes under abnormal excessive voltage.
• Package & Mounting — Radial can, snap-in terminal type (φ35 × 30 mm), suitable for secure chassis/board mounting in production assemblies.
• Electrical Characteristics — Polarized capacitor with ±20% capacitance tolerance and leakage current specified per datasheet (I ≤ 3√CV μA after 5 minutes at 20°C).
• Environmental Compliance — RoHS compliant per provided product information.

Typical Applications

• Industrial power supplies — Bulk smoothing and energy storage for high-voltage DC rails where fluctuation-tolerant capacitors are required.
• Inverters and motor drives — DC link and ripple suppression in commercial and industrial motor control systems.
• Commercial power equipment — Energy buffering and voltage stabilization in equipment exposed to varying supply conditions.

Unique Advantages

• Extended high-temperature life: 2000 hours at 105°C provides predictable end-of-life performance for thermally demanding designs.
• High-voltage capability: 420 V rating allows use in higher-voltage DC systems without additional series stacking.
• Robust ripple handling: Specified ripple currents at both low and high frequency provide design flexibility for different power topologies.
• Improved safety measures: Series-level safety features and a pressure relief vent reduce risk during abnormal over-voltage events.
• Production-ready packaging: Tray packing and snap-in mounting streamline assembly for mass-production environments.
• Regulatory compliance: RoHS status supports environmental and regulatory needs for commercial projects.
