LAKW6330MELZ25

The LAKW6330MELZ25 is a Nichicon LAK series aluminum electrolytic capacitor in a snap‑in terminal radial can designed for high‑voltage, high‑temperature applications. It provides 33 µF at a rated voltage of 420 V and is intended for general‑purpose use where voltage fluctuation and elevated operating temperatures are expected.

Built for endurance and safety, this snap‑in capacitor is specified for operation from −25 °C to +105 °C, withstands rated ripple current for 2000 hours at 105 °C, and includes improved safety features for abnormally excessive voltage. The part is RoHS compliant.

Key Features

• Voltage & Capacitance — Rated capacitance of 33 µF at 420 V for high‑voltage DC applications within the LAK series’ extended voltage range (200 V, 400 V, 420 V).
• High‑Temperature Endurance — Engineered to meet endurance requirements after 2000 hours of D.C. bias plus rated ripple current at 105 °C with capacitance change within ±20% of initial value.
• Broad Operating Temperature — Specified operating temperature range from −25 °C to +105 °C for use in elevated ambient conditions.
• Ripple Current Capability — Rated ripple current performance: 250 mA at 120 Hz and 287.5 mA at 10 kHz, supporting AC ripple handling in high‑voltage circuits.
• Safety Performance — Improved safety features and a pressure relief vent designed to operate under abnormal voltage without dangerous conditions such as flames or dispersion of parts.
• Mounting & Package — Snap‑in terminal, radial can package for secure board mounting and mechanical stability in PCB assemblies; size L: 2.5 × D: 2.2 cm.
• Leakage & Loss Characteristics — Leakage current controlled per datasheet (I ≤ 3√CV μA after 5 minutes at 20 °C) and tan δ ≤ 0.20 (120 Hz, 20 °C) for predictable performance.
• Compliance — Conforms to RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General‑purpose power filtering — Bulk smoothing and DC filtering in circuits requiring a 420 V, 33 µF electrolytic solution.
• High‑voltage DC link circuits — Use where extended voltage range and controlled ripple handling are required at elevated temperature.
• Equipment operating with supply fluctuations — Suited for devices and systems deployed in environments with fluctuating supply voltage due to its improved safety measures and endurance at 105 °C.

Unique Advantages

• High‑voltage capability: 420 V rating enables use in higher DC voltage systems within the LAK series’ extended voltage options.
• Validated high‑temperature endurance: Designed to withstand 2000 hours of rated ripple current at 105 °C, providing predictable long‑term behavior under thermal stress.
• Safety‑focused design: Pressure relief vent and improved safety features minimize hazardous failure modes under abnormal voltage conditions.
• Reliable ripple handling: Specified ripple currents at 120 Hz and 10 kHz support both low‑ and high‑frequency ripple environments.
• Measured leakage and dissipation: Leakage current and tan δ limits are specified (I ≤ 3√CV μA; tan δ ≤ 0.20) for controlled electrical behavior after voltage application.
• Regulatory compliance: RoHS conformity addresses material restriction requirements for modern electronics production.
