LAK2G820MELZ30

The LAK2G820MELZ30 is an aluminum electrolytic capacitor in a snap-in terminal, radial can package designed for general-purpose high-voltage applications. It provides 82 µF capacitance at a 400 V rated voltage in a compact 22 mm × 30 mm form factor.

Engineered for use in equipment operating in voltage-fluctuating environments, this Nichicon LAK series part combines high-voltage capability, extended endurance at elevated temperature, and built-in safety features to support reliable power filtering and energy storage tasks.

Key Features

• Capacitance and Voltage — 82 µF nominal capacitance at a 400 V rated voltage, ±20% tolerance.
• Snap‑in Radial Can Package — Snap-in terminal type provides secure board mounting for power assemblies and filter banks.
• High Temperature Endurance — Designed to withstand 2000 hours application of rated ripple current at 105°C, maintaining capacitance within ±20% after endurance testing.
• Ripple Current Performance — Rated ripple current: 500 mA at 120 Hz and 575 mA at 10 kHz, supporting AC ripple handling in power circuits.
• Safety Features — Improved safety for abnormally excessive voltage; pressure relief vent is designed to operate without flames, ignition, or dispersion of case fragments under tested conditions.
• Operating Temperature Range — −25°C to +105°C suitable for elevated-temperature environments.
• RoHS Compliant — Conforms to RoHS directive (2011/65/EU, (EU)2015/863).
• Compact Dimensions — Size approximately 22 mm diameter × 30 mm length for space-conscious designs.

Typical Applications

• Industrial and utility equipment — General-purpose high-voltage filtering in equipment used in voltage-fluctuating areas where endurance and safety matter.
• Power supply filtering — Bulk and smoothing capacitance for high-voltage power supplies and converter front-ends operating up to 400 V.
• Power conversion modules — Energy storage and ripple suppression in assemblies that require sustained ripple current at elevated temperatures.

Unique Advantages

• Proven high-temperature endurance: Rated to withstand 2000 hours of rated ripple current at 105°C, delivering predictable capacitance stability over extended use.
• High-voltage capability: 400 V rating with the LAK series offering extended voltage options (200 V and 420 V) for design flexibility across voltage rails.
• Built-in safety venting: Pressure relief vent designed to operate safely under abnormal voltages to reduce risk of flames or case dispersion.
• Compact, secure mounting: Snap-in radial can package enables robust mechanical retention for power assemblies and cabinet installations.
• Measurable ripple handling: Specified ripple currents at 120 Hz and 10 kHz allow designers to match component selection to target operating conditions.
• Regulatory compliance: RoHS conformity supports usage in designs requiring restricted-substance compliance.
