LAK2G820MELB20

The LAK2G820MELB20 is a Nichicon aluminum electrolytic, snap‑in terminal capacitor specified for 400 V operation with 82 µF nominal capacitance. It is a polarized, radial can device designed for general‑purpose high‑voltage applications where stable capacitance, controlled dissipation, and enhanced safety are required.

Key value propositions include a 105°C permissible operating range with 2000 hours endurance at 105°C, defined ripple current ratings at both low and high frequencies, and built‑in safety features for tolerance to abnormal voltages. The part is RoHS compliant and supplied in tray packing for production use.

Key Features

• Electrical Performance — 82 µF nominal capacitance at a rated voltage of 400 V with ±20% tolerance and a maximum tan δ of 0.20 (measured at 20°C, 120 Hz).
• Ripple Current Capability — Rated ripple current of 500 mA at 120 Hz (low frequency) and 575 mA at 10 kHz (high frequency) to support AC ripple and decoupling in high‑voltage circuits.
• Low Leakage — Specified leakage current of 540 µA, supporting stable performance after application of rated voltage.
• Thermal & Reliability — Operates from −25°C to +105°C with endurance tested to 2000 hours at 105°C (with DC bias plus rated ripple current applied), meeting the LAK series endurance criteria.
• Safety Features — Designed with improved safety measures for abnormally excessive voltage and a pressure relief vent that operates under abnormal conditions per series specifications.
• Mechanical & Packaging — Snap‑in radial can package, size φ30 × 20L (30 mm diameter × 20 mm length), supplied in tray packing and in mass production status for volume designs.
• Regulatory — RoHS compliant as specified in product data.

Typical Applications

• Industrial power systems — For high‑voltage circuits that require stable capacitance and controlled dissipation in environments with fluctuating supply voltage.
• General‑purpose high‑voltage electronics — Provides polarized capacitance and ripple handling in 400 V designs where long‑term endurance at elevated temperatures is required.
• Equipment operating in voltage‑fluctuating areas — The LAK series safety and voltage tolerance features suit applications exposed to abnormal voltage conditions.

Unique Advantages

• 400 V rating — Enables use in higher‑voltage designs without additional derating for nominal operation.
• Defined high‑temperature endurance — 2000 hours at 105°C under rated conditions provides predictable life performance for thermal stress environments.
• Dual‑frequency ripple specification — Ripple current ratings at both 120 Hz and 10 kHz give clear guidance for low‑ and high‑frequency applications.
• Enhanced safety design — Improved safety features for abnormal voltage and a functioning pressure relief vent help mitigate hazardous failure modes.
• Production‑ready packaging — Tray packing and mass production availability simplify BOM planning and assembly for volume designs.
• RoHS compliance — Meets RoHS directive requirements for restricted substances.
