LAK2G470MELZ25ZB

The LAK2G470MELZ25ZB is a snap-in terminal aluminum electrolytic capacitor from Nichicon’s LAK series, specified for high-voltage, high-temperature operation. It provides 47 µF nominal capacitance at a 400 V rating with snap-in radial can packaging for robust mechanical mounting.

Designed for general-purpose power applications and equipment exposed to voltage fluctuations, this part emphasizes thermal endurance, safety features and defined ripple/ leakage performance for reliable operation in demanding environments.

Key Features

• Capacitance & Voltage — 47 µF nominal capacitance at a 400 V rated voltage, ±20% tolerance for predictable bulk energy storage and filtering.
• High-Temperature Endurance — Rated for operation from −25°C to +105°C with a lifetime of 2000 hours at 105°C when subjected to rated ripple current and DC bias.
• Snap-In Radial Can Package — φ22 × 25 mm can with snap-in terminals for secure board mounting and mechanical stability in mass-production assemblies.
• Ripple Performance — Specified ripple current capability of 350 mA at 120 Hz (low frequency) and 402.5 mA at 10 kHz (high frequency) to handle AC stress on the capacitor.
• Leakage & Loss Characteristics — Low leakage current specified at 410 µA and tanδ ≤ 0.20 (120 Hz, 20°C) for controlled dissipation and predictable behavior under bias.
• Safety Features — Designed with pressure relief venting and improved safety performance for abnormal over-voltage conditions as part of the LAK series specifications.
• Compliance & Packaging — RoHS-compliant and offered in tray packing for production use.

Typical Applications

• General-purpose power circuits — Bulk filtering and smoothing where 400 V rated capacitance and defined ripple capability are required.
• Equipment subject to voltage fluctuation — Suitable for systems operating in environments with varying supply conditions thanks to enhanced safety and voltage endurance.
• High-temperature installations — Use in designs that require continuous operation at elevated ambient temperatures up to +105°C with long endurance.

Unique Advantages

• High thermal endurance: 2000 hours at 105°C rated lifetime ensures stability in high-temperature applications.
• Defined ripple capability: Both low- and high-frequency ripple current ratings (350 mA at 120 Hz, 402.5 mA at 10 kHz) allow selection with quantitative stress margins.
• Compact snap-in format: φ22 × 25 mm radial can with snap-in terminals provides secure mounting and straightforward placement for automated assemblies.
• Controlled leakage and dissipation: Specified leakage current (410 µA) and tanδ ≤ 0.20 enable predictable DC bias performance and loss budgeting.
• Safety-oriented design: Pressure relief venting and series-level safety performance reduce risk under abnormal voltages.
• RoHS compliant and production-ready: Tray packing and mass-production availability support volume manufacturing and regulatory requirements.
