LAKW6820MELZ35

The LAKW6820MELZ35 is an aluminum electrolytic, snap‑in terminal capacitor designed for general‑purpose power applications. It delivers 82 µF capacitance at a 420 V rating with a robust high‑temperature endurance profile, making it suitable for equipment exposed to elevated operating temperatures and fluctuating voltages.

Configured in a radial, snap‑in can (φ22×35L) and supplied in tray packing for mass production, this component targets power filtering, smoothing and decoupling roles where durability, ripple handling and safety under abnormal voltage are important.

Key Features

• Capacitance & Voltage — 82 µF capacitance rated at 420 V for high‑voltage power applications.
• High‑Temperature Endurance — Specified lifetime of 2000 hours at 105°C when subjected to rated ripple current and DC bias, supporting sustained operation in hot environments.
• Ripple Current Capability — Rated ripple current of 640 mA at 120 Hz and 736 mA at 10 kHz to support power supply smoothing and transient handling.
• Electrical Stability — Capacitance tolerance ±20% and loss tangent (tan δ) ≤ 0.20 at 120 Hz, 20°C, with leakage current defined by I ≤ 3√CV μA (after 5 minutes at 20°C) according to the datasheet.
• Package & Mounting — Radial snap‑in can (φ22×35L) for secure board mounting and streamlined assembly; supplied in tray packing for production workflows.
• Safety & Abnormal Voltage Handling — Designed with improved safety features and a pressure‑relief vent for controlled response under abnormally excessive voltage conditions, supporting use in voltage‑fluctuating environments.
• RoHS Compliant — Conforms to RoHS requirements for lead‑free manufacturing environments.

Typical Applications

• General‑purpose power supply filtering — Bulk decoupling and smoothing in power stages where 420 V rating and 82 µF capacitance are required.
• Equipment in voltage‑fluctuating areas — Suitable for systems subject to supply variations thanks to enhanced safety handling for abnormal voltages.
• High‑temperature systems — Use in assemblies operating up to 105°C, leveraging the 2000‑hour endurance specification at that temperature.

Unique Advantages

• High voltage tolerance: 420 V rating enables application in elevated‑voltage circuits without compromise to capacitance value.
• Long high‑temperature life: 2000 hours at 105°C under rated conditions provides predictable endurance in hot environments.
• Strong ripple handling: Specified ripple currents at both 120 Hz and 10 kHz support performance across typical power conversion frequencies.
• Snap‑in mounting for production: Radial snap‑in can and tray packing simplify PCB assembly and handling in mass production.
• Defined electrical limits: Clear leakage current and tan δ specifications make it straightforward to design to expected leakage and loss budgets.
• Safety‑minded design: Pressure‑relief vent and abnormal voltage protections reduce risk in fluctuating voltage environments.
