LAKW6330MELZ25ZB

The LAKW6330MELZ25ZB is a snap‑in terminal aluminum electrolytic capacitor from Nichicon’s LAK series, rated at 420 V with a capacitance of 33 µF. It is a radial, can‑style, polarized capacitor designed for general‑purpose power applications where high voltage tolerance and robust ripple handling are required.

This part is optimized for equipment operating in environments with fluctuating supply voltages: it offers extended voltage options (200 V, 400 V and 420 V), improved safety features for abnormally excessive voltage, and endurance under elevated temperature and ripple stress.

Key Features

• High Voltage Rating — Rated at 420 V and offered within an extended voltage range that includes 200 V and 400 V, supporting higher DC bus and power conversion requirements.
• Electrical Performance — 33 µF capacitance with ±20% tolerance at 120 Hz, leakage current specified by I ≤ 3√(C·V) (μA) after 5 minutes at 20°C, and tan δ ≤ 0.20 at 120 Hz, 20°C.
• Ripple Current Capability — Designed to tolerate rated ripple current with specified values of 250 mA at 120 Hz and 287.5 mA at 10 kHz, supporting smoothing and filtering under AC ripple stress.
• High‑Temperature Endurance — Endurance rating of 2000 hours at 105°C with D.C. bias plus rated ripple current; after the endurance test, capacitance change remains within ±20%, tan δ remains within 200% of initial specification, and leakage current stays at or below initial specified value.
• Safety Features — Includes a pressure relief vent designed to operate under abnormal excessive voltage conditions without dangerous outcomes such as flames or case dispersion.
• Package & Mounting — Radial, can‑type snap‑in package for secure board mounting and mechanical stability in high‑ripple applications; size L: 2.5 × D: 2.2 cm (radial can).
• Compliance — RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• Power Supplies — Bulk smoothing and decoupling in high‑voltage DC power supplies where extended voltage tolerance and ripple endurance are required.
• Industrial Equipment — Filtering and energy storage in industrial systems exposed to fluctuating or unstable supply voltages; improved safety features address abnormal overvoltage events.
• Power Conversion — Energy smoothing and DC link support in power converters and inverters that operate with elevated DC voltages and require durable high‑temperature performance.
• General Purpose Electronics — Applications that demand a polarized aluminum electrolytic with snap‑in mounting, compact can footprint, and validated high‑temperature ripple endurance.

Unique Advantages

• Extended voltage flexibility: Availability across 200 V, 400 V and 420 V options lets designers choose higher voltage margin for DC bus and conversion topologies.
• Verified high‑temperature endurance: 2000 hours at 105°C with rated ripple current provides predictable life behavior for designs subject to elevated thermal stress.
• Clear safety behavior: A pressure relief vent that operates under abnormal excessive voltage conditions reduces the risk of dangerous failures.
• Measured ripple performance: Specified ripple current ratings at 120 Hz and 10 kHz support use in both line‑frequency and higher‑frequency power stages.
• RoHS compliance: Conforms to RoHS directives (2011/65/EU, (EU)2015/863) for regulatory alignment in commercial and industrial products.
