LAK2G820MELZ30ZB

The LAK2G820MELZ30ZB is a Nichicon LAK series aluminum electrolytic capacitor in a snap‑in radial can package. It provides 82 µF capacitance at a 400 V rated voltage and is designed for general-purpose power applications that require high-voltage filtering and energy buffering.

Built for robust thermal and electrical performance, this part offers a 2000‑hour endurance at 105°C and enhanced safety features for abnormal overvoltage conditions, making it suitable for equipment operating in environments with voltage fluctuations.

Key Features

• Capacitance & Voltage — 82 µF nominal capacitance with a 400 V rated voltage and ±20% tolerance.
• Package & Mounting — Snap‑in radial can construction (φ22 × 30 mm) for secure chassis mounting and high‑current board connections.
• Operating Temperature & Endurance — Rated for −25°C to +105°C with a guaranteed lifetime of 2000 hours at 105°C.
• Ripple Current Capability — Specified ripple current of 500 mA at 120 Hz and 575 mA at 10 kHz to support AC ripple and switching applications.
• Safety Features — Designed with improved safety for abnormally excessive voltage and a pressure relief vent that operates under abnormal conditions to prevent dangerous failures.
• Compliance & Packaging — RoHS‑compliant and supplied in tray packing for mass production handling.
• Polarized — Polarized aluminum electrolytic suitable for DC energy storage and smoothing applications.

Typical Applications

• Power supply filtering — Bulk smoothing and ripple reduction on high‑voltage DC rails where 400 V rating is required.
• Industrial equipment — Energy buffering and decoupling in equipment subject to fluctuating supply voltages.
• Power conversion modules — DC bus and intermediate circuit support in converters and inverters operating at elevated DC voltages.
• General-purpose high-voltage circuits — Reliable high‑voltage capacitance for a wide range of electronic systems requiring polarized aluminum electrolytics.

Unique Advantages

• High-voltage endurance: 400 V rating combined with 2000 hours endurance at 105°C provides predictable life under elevated temperature and voltage stress.
• Designed for fluctuating voltages: Series‑level design and safety features reduce risk in equipment exposed to abnormal voltage conditions.
• Robust ripple handling: Defined ripple current specs at both low and high frequencies (500 mA @120 Hz, 575 mA @10 kHz) help maintain performance in switching environments.
• Secure mounting: Snap‑in radial can provides strong mechanical retention for chassis and cabinet installations.
• Production ready: Tray packing and mass‑production availability support assembly line throughput and inventory management.
• Regulatory compliance: RoHS‑compliant construction supports conformance to environmental restrictions.
