LAK2G820MELA25ZB

The LAK2G820MELA25ZB is a snap‑in terminal aluminum electrolytic capacitor from Nichicon’s LAK series, offering 82 μF capacitance at a 400 V rating. Designed for general‑purpose power applications, it provides high‑voltage capability, elevated temperature endurance and improved safety characteristics for use in equipment exposed to fluctuating voltages.

Key value propositions include a 105°C rated operating range with proven 2000‑hour endurance, robust ripple handling at both low and high frequencies, and a compact φ25 × 25 mm snap‑in can for reliable mounting in production assemblies.

Key Features

• Capacitance & Voltage — 82 μF nominal capacitance with a 400 V rated voltage for bulk energy storage and smoothing in higher‑voltage power circuits.
• Endurance at Elevated Temperature — Rated for 2000 hours at 105°C under specified ripple conditions, supporting sustained operation in hot environments.
• Low Loss (tan δ) — Tangent of loss angle (tan δ) specified at 0.20 max measured at 20°C, 120 Hz, enabling predictable dissipation characteristics.
• Ripple Current Capability — Low‑frequency ripple current 500 mA (120 Hz) and high‑frequency capability 575 mA (100 kHz), for reliable performance across switching and line‑frequency conditions.
• Leakage Current — Specified leakage current of 540 μA for predictable standby and leakage behavior after voltage application.
• Robust Snap‑in Package — Radial, can snap‑in package (φ25 × 25 mm) for secure board mounting and high‑volume assembly; supplied in tray packing for production handling.
• Safety Features — LAK series design includes improved safety performance for abnormally excessive voltage and a pressure relief vent that operates without dangerous outcomes.
• Environmental Compliance — RoHS compliant.

Typical Applications

• Industrial Power Supplies — Bulk smoothing and energy storage for AC/DC converters and rectifier outputs where 400 V ratings and elevated temperature endurance are required.
• Commercial UPS and Backup Systems — Energy hold‑up and filtering in high‑voltage DC sections demanding dependable ripple handling and long endurance at 105°C.
• Power Conversion and Motor Drives — DC link smoothing and ripple attenuation in systems subject to switching and line frequency ripple.

Unique Advantages

• High‑voltage capability: 400 V rating allows use in higher‑voltage power rails without adding series components.
• Elevated temperature endurance: 2000‑hour rating at 105°C provides predictable life in thermally demanding installations.
• Dual‑frequency ripple performance: Specified ripple currents at 120 Hz and 100 kHz support both line‑frequency and switching applications.
• Compact, production‑friendly package: φ25 × 25 mm snap‑in can in tray packing simplifies assembly and board retention for automated manufacturing.
• Safety‑oriented design: Series‑level safety features and a pressure relief vent reduce the risk associated with abnormal overvoltage events.
• Regulatory compliance: RoHS‑compliant construction meets common environmental requirements for commercial and industrial products.
