LAKW6820MELA30

The LAKW6820MELA30 from Nichicon is a snap‑in terminal aluminum electrolytic capacitor in the LAK series, rated 420 V with 82 µF capacitance and ±20% tolerance. Engineered for general‑purpose power applications, it delivers high ripple endurance at elevated temperatures and includes safety features for use in environments with fluctuating or abnormal voltages.

This tray‑packed, mass‑production part is polarized, RoHS‑compliant and designed for systems that require stable capacitance, controlled leakage, and robust operation up to 105°C.

Key Features

• Capacitance & Voltage — 82 µF nominal capacitance at a rated voltage of 420 V with ±20% tolerance, suitable for higher‑voltage power systems.
• High‑Temperature Endurance — Rated for operation from -25°C to +105°C with a specified lifetime of 2000 hours at 105°C under rated ripple and DC bias.
• Ripple Current Performance — Specified ripple current handling of 640 mA at 120 Hz and 736 mA at 10 kHz to support AC ripple filtering and smoothing in power circuits.
• Safety Features — Designed with a pressure relief vent and enhanced safety measures for abnormally excessive voltage, reducing the risk of dangerous failure modes.
• Electrical Characteristics — Low leakage behavior defined by I ≤ 3√(C·V) µA after 5 minutes at 20°C, and tan δ ≤ 0.20 (120 Hz, 20°C) for predictable dissipation.
• Package & Mounting — Radial can, snap‑in terminal style (φ25 × 30 mm body), tray packing for efficient handling in production environments.
• RoHS Compliance — Meets RoHS directive requirements for lead‑free environmental compliance.

Typical Applications

• Voltage‑fluctuating power equipment — Suitable where supply voltages vary; extended voltage capability and safety design address abnormal voltage conditions.
• High‑temperature power modules — Use in modules operating up to 105°C where sustained ripple endurance (2000 hours at 105°C) is required.
• AC ripple filtering and smoothing — Handles specified ripple currents at both low and high frequencies (120 Hz and 10 kHz) for stable DC bus performance.
• General‑purpose industrial power systems — Polarized snap‑in mounting and tray packing support efficient assembly and reliable operation in production hardware.

Unique Advantages

• High‑voltage capability: 420 V rating provides margin for higher‑voltage power rails without changing capacitor family.
• Elevated temperature durability: 2000‑hour endurance at 105°C supports long‑term operation in hot‑running environments.
• Measured ripple performance: Published ripple current ratings at 120 Hz and 10 kHz allow designers to size capacitors against real workload conditions.
• Safety‑focused design: Pressure relief vent and improved abnormal‑voltage handling reduce risk in fluctuating supply environments.
• Production‑friendly packaging: Tray packing and snap‑in terminals simplify automated handling and assembly for volume manufacturing.
• Predictable electrical behavior: Defined limits for leakage current and tan δ help ensure stable performance and easier qualification in designs.
